Infertility, Male: The inability of the male to effect FERTILIZATION of an OVUM after a specified period of unprotected intercourse. Male sterility is permanent infertility.Infertility, Female: Diminished or absent ability of a female to achieve conception.Infertility: Inability to reproduce after a specified period of unprotected intercourse. Reproductive sterility is permanent infertility.Signal Transduction: The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.Reproductive Techniques, Assisted: Clinical and laboratory techniques used to enhance fertility in humans and animals.Fallopian Tube Diseases: Diseases involving the FALLOPIAN TUBES including neoplasms (FALLOPIAN TUBE NEOPLASMS); SALPINGITIS; tubo-ovarian abscess; and blockage.Spermatozoa: Mature male germ cells derived from SPERMATIDS.

In addition to reproductive organ secretions, it contains SPERMATOZOA and their nutrient plasma.Semen Analysis: The quality of SEMEN, an indicator of male fertility, can be determined by semen volume, pH, sperm concentration (SPERM COUNT), total sperm number, sperm viability, sperm vigor (SPERM MOTILITY), normal sperm morphology, ACROSOME integrity, and the concentration of WHITE BLOOD CELLS.Reproductive Techniques: Methods pertaining to the generation of new individuals, including techniques used in selective BREEDING, cloning (CLONING, ORGANISM), and assisted reproduction (REPRODUCTIVE TECHNIQUES, ASSISTED).Pregnancy Rate: The ratio of the number of conceptions (CONCEPTION) including LIVE BIRTH; STILLBIRTH; and fetal losses, to the mean number of females of reproductive age in a population during a set time period.Testis: The male gonad containing two functional parts: the SEMINIFEROUS TUBULES for the production and transport of male germ cells (SPERMATOGENESIS) and the interstitial compartment containing LEYDIG CELLS that produce ANDROGENS.Clomiphene: A triphenyl ethylene stilbene derivative which is an estrogen agonist or antagonist depending on the target tissue. Note that ENCLOMIPHENE and ZUCLOMIPHENE are the (E) and (Z) isomers of Clomiphene respectively.Asthenozoospermia: A condition in which the percentage of progressively motile sperm is abnormally low. In men, it is defined as Anovulation: Suspension or cessation of OVULATION in animals or humans with follicle-containing ovaries (OVARIAN FOLLICLE). Depending on the etiology, OVULATION may be induced with appropriate therapy.Sperm Injections, Intracytoplasmic: An assisted fertilization technique consisting of the microinjection of a single viable sperm into an extracted ovum.

Its wall consists of three histologic layers: serous, muscular, and an internal mucosal layer lined with both ciliated and secretory cells.Ovary: The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.Orchitis: Inflammation of a TESTIS. It has many features of EPIDIDYMITIS, such as swollen SCROTUM; PAIN; PYURIA; and FEVER.

Follicle-stimulating hormone stimulates GAMETOGENESIS and the supporting cells such as the ovarian GRANULOSA CELLS, the testicular SERTOLI CELLS, and LEYDIG CELLS. FSH consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity.Chlamydia Infections: Infections with bacteria of the genus CHLAMYDIA.Endometrium: The mucous membrane lining of the uterine cavity that is hormonally responsive during the MENSTRUAL CYCLE and PREGNANCY. The endometrium undergoes cyclic changes that characterize MENSTRUATION. After successful FERTILIZATION, it serves to sustain the developing embryo.Fertility Agents: Drugs used to increase fertility or to treat infertility.Ovarian Diseases: Pathological processes of the OVARY.Chlamydia trachomatis: Type species of CHLAMYDIA causing a variety of ocular and urogenital diseases.Epididymis: The convoluted cordlike structure attached to the posterior of the TESTIS.

Major gonadotropins are glycoproteins produced primarily by the adenohypophysis (GONADOTROPINS, PITUITARY) and the placenta (CHORIONIC GONADOTROPIN). In some species, pituitary PROLACTIN and PLACENTAL LACTOGEN exert some luteotropic activities.Sertoli Cells: Supporting cells projecting inward from the basement membrane of SEMINIFEROUS TUBULES. They surround and nourish the developing male germ cells and secrete ANDROGEN-BINDING PROTEIN and hormones such as ANTI-MULLERIAN HORMONE. The tight junctions of Sertoli cells with the SPERMATOGONIA and SPERMATOCYTES provide a BLOOD-TESTIS BARRIER.Reproductive Behavior: Human behavior or decision related to REPRODUCTION.Contraception, Immunologic: Contraceptive methods based on immunological processes and techniques, such as the use of CONTRACEPTIVE VACCINES.Social Alienation: The state of estrangement individuals feel in cultural settings that they view as foreign, unpredictable, or unacceptable.Tissue Adhesions: Pathological processes consisting of the union of the opposing surfaces of a wound.Live Birth: The event that a FETUS is born alive with heartbeats or RESPIRATION regardless of GESTATIONAL AGE. Such liveborn is called a newborn infant (INFANT, NEWBORN).Cryopreservation: Preservation of cells, tissues, organs, or embryos by freezing. In histological preparations, cryopreservation or cryofixation is used to maintain the existing form, structure, and chemical composition of all the constituent elements of the specimens.Spermatids: Male germ cells derived from the haploid secondary SPERMATOCYTES. Without further division, spermatids undergo structural changes and give rise to SPERMATOZOA.Vasovasostomy: Surgical anastomosis or fistulization of the spermatic ducts to restore fertility in a previously vasectomized male.Seminiferous Tubules: The convoluted tubules in the TESTIS where sperm are produced (SPERMATOGENESIS) and conveyed to the RETE TESTIS. Spermatogenic tubules are composed of developing germ cells and the supporting SERTOLI CELLS.Cryptorchidism: A developmental defect in which a TESTIS or both TESTES failed to descend from high in the ABDOMEN to the bottom of the SCROTUM. Testicular descent is essential to normal SPERMATOGENESIS which requires temperature lower than the BODY TEMPERATURE. Cryptorchidism can be subclassified by the location of the maldescended testis.Sperm-Ovum Interactions: Interactive processes between the oocyte (OVUM) and the sperm (SPERMATOZOA) including sperm adhesion, ACROSOME REACTION, sperm penetration of the ZONA PELLUCIDA, and events leading to FERTILIZATION.Marriage: The social institution involving legal and/or religious sanction whereby individuals are joined together.Menstruation Disturbances: Variations of menstruation which may be indicative of disease.Menotropins: Extracts of urine from menopausal women that contain high concentrations of pituitary gonadotropins, FOLLICLE STIMULATING HORMONE and LUTEINIZING HORMONE.

The FSH:LH ratio and degree of purity vary in different preparations.Sperm Tail: The posterior filiform portion of the spermatozoon (SPERMATOZOA) that provides sperm motility.Sertoli Cell-Only Syndrome: A type of male infertility in which no germ cells are visible in any of the biopsied SEMINIFEROUS TUBULES (type I) or in which germ cells are present in a minority of tubules (type II). Clinical features include AZOOSPERMIA, normal VIRILIZATION, and normal chromosomal complement.Laparoscopy: A procedure in which a laparoscope (LAPAROSCOPES) is inserted through a small incision near the navel to examine the abdominal and pelvic organs in the PERITONEAL CAVITY. If appropriate, biopsy or surgery can be performed during laparoscopy.Oocyte Donation: Transfer of preovulatory oocytes from donor to a suitable host. Oocytes are collected, fertilized in vitro, and transferred to a host that can be human or animal.Time-to-Pregnancy: Time interval, or number of non-contraceptive menstrual cycles that it takes for a couple to conceive.Oceania: The islands of the central and South Pacific, including Micronesia, Melanesia, Polynesia, and traditionally Australasia. (Random House Dictionary, 2d ed)Diagnostic Techniques, Obstetrical and Gynecological: Methods and procedures for the diagnosis of conditions related to pregnancy, labor, and the puerperium and of diseases of the female genitalia. It includes also demonstration of genital and pregnancy physiology.Reproductive Health Services: Health care services related to human REPRODUCTION and diseases of the reproductive system. Services are provided to both sexes and usually by physicians in the medical or the surgical specialties such as REPRODUCTIVE MEDICINE; ANDROLOGY; GYNECOLOGY; OBSTETRICS; and PERINATOLOGY.Follicle Stimulating Hormone, Human: A major gonadotropin secreted by the human adenohypophysis (PITUITARY GLAND, ANTERIOR). Follicle-stimulating hormone stimulates GAMETOGENESIS and the supporting cells such as the ovarian GRANULOSA CELLS, the testicular SERTOLI CELLS, and the LEYDIG CELLS. FSH consists of two noncovalently linked subunits, alpha and beta. The alpha subunit is common in the three human pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity.Gonadal Disorders: Pathological processes of the OVARIES or the TESTES.Oocyte Retrieval: Procedures to obtain viable OOCYTES from the host. Oocytes most often are collected by needle aspiration from OVARIAN FOLLICLES before OVULATION.Testosterone: A potent androgenic steroid and major product secreted by the LEYDIG CELLS of the TESTIS. Its production is stimulated by LUTEINIZING HORMONE from the PITUITARY GLAND. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to DIHYDROTESTOSTERONE or ESTRADIOL.Spiritual Therapies: Mystical, religious, or spiritual practices performed for health benefit.Insemination, Artificial, Heterologous: Human artificial insemination in which the semen used is that of a man other than the woman's husband.Zona Pellucida: A tough transparent membrane surrounding the OVUM. It is penetrated by the sperm during FERTILIZATION.Salpingitis: Inflammation of the uterine salpinx, the trumpet-shaped FALLOPIAN TUBES, usually caused by ascending infections of organisms from the lower reproductive tract. Salpingitis can lead to tubal scarring, hydrosalpinx, tubal occlusion, INFERTILITY, and ectopic pregnancy (PREGNANCY, ECTOPIC)Sperm Retrieval: Procedures to obtain viable sperm from the male reproductive tract, including the TESTES, the EPIDIDYMIS, or the VAS DEFERENS.

According to clinical studies, around 35% of all infertility cases are related to male fertility issues. Male infertility can be caused due to several factors. Fortunately, male infertility treatment is now available at the top Fertility Treatment Clinic, Pacific Reproductive Center in Los Angeles. Male infertility can be divided into four main categories.. Pre-testicular causes. These are problems that occur due to some form of hormone deficiency, such as a problem with the pituitary gland or hypothalamus. Men who have this type of infertility often have underdeveloped male characteristics. As part of male infertility ...
Male infertility is defined as a condition where the male partner is unable to make his female partner pregnant even after a year of sexual intercourse without using birth control. It is found that 20% of the total infertility i.e. male and female is because of male induced factors. One or more than one medical conditions or factors can contribute to male infertility. The significant causes include low sperm production, hormonal imbalance, abnormal sperm function or blockages in male reproductive systems. However, sometimes the symptoms or conditions causing male infertility are simply not identifiable. Although, presently, limited number of medical treatments exist at ...
Infertility in Men. Infertility is the medical term for a couples inability to become pregnant after one year of sexual intercourse. Based on current statistics, around 15% of couples in the U.S. and Europe have problems with conception. Fertility depends upon several factors, for both the man and the woman. Male factors contribute to 30% of infertility. In the past, men with infertility had few options. However, improvements in technology have now gave hope to many couples.. Causes of Male Infertility. For a man to be fertile, he must have a normal functioning pituitary gland and hypothalamus (hormone-producing structures of the brain), as well as adequate testicular function. Around 35% of cases of male ...

The most common female infertility cause is an ovulation disorder. Other causes of female infertility include blocked fallopian tubes, which can occur when a woman has had pelvic inflammatory disease or endometriosis (a sometimes painful condition causing adhesions and cysts). Congenital anomalies (birth defects) involving the structure of the uterus and uterine fibroids are associated with repeated miscarriages. In females, possible factors implicated include an active sexual life starting at a very young age, an increased number of pregnancy terminations and multiple sexual partners (sexually transfered diseases as chlamydia etc). Most importantly, concern has been expressed about the decision some women have made in postponing having a baby, giving reasons such as education, career advancement and not yet finding the "right" man until ...

Book Review by: Sonu Chandiram. Hope has been increasing in recent years for infertile males, write the editors of this book - Drs. Marc Goldstein and Peter Schlagel - in the Preface. The write: "Dramatic advances in the diagnosis and treatment of male infertility allow conception for couples previously considered untreatable," pointing out to gains from tests of sperm function, contributing to better understanding of the causes.. The editors also write that in vitro fertilization combined with intracytoplasmic sperm injection (IVF/ICSI) of a human oocyte, as discussed and illustrated in chapter 28, has revolutionized the treatment of male factor infertility.. Sixty-seven urologists, many of whom are professors of urology and reproductive medicine, or surgeons with specialist knowledge and surgical experience on male ...
In this study, we have aimed to determine the hormonal profile of infertile women undergoing diagnostic laparoscopy as well as the presence of other hormonal abnormalities associated with PCOS. Measurement of hormone level is an essential part of investigation of infertility. Measurement of serum LH and serum FSH is done invariably in all infertile patients especially those with irregular menstruation. Most common hormonal disorder observed in female infertile patient is polycystic ovarian syndrome (PCOS). The findings of one large series of 1700 women with PCOS shown to have serum LH concentration was significantly higher in primary infertility women than those of secondary infertility [14]. In our study, mean level of serum LH was 10.66±18.90 in primary ...

BACKGROUND Although FIVET and ICSI efficacy and efficiency are continuously increasing, intrauterine insemination (IUI) is a very used technique for many different types of sterility. It is also used in male sterility for its cost/benefit positive rate. Pregnancies frequency obtained after IUI in male factor infertility cases, with or without ovarian stimulation, shows the value of this work. METHODS We evaluated 149 insemination cycles in 34 couples with a male infertility diagnosis confirmed after at least 2 semen analysis, according to OMS criteria. All the 34 patients had at least one Fallopian tube open and some spontaneous ovulatory cycle to enter in this study. The patients without biochemical pregnancy signs after 6 intrauterine insemination cycles were induced to multiple ovulations through oral administration of 50 mg of Clomifene citrate from ...
Infertility affects 1 in 6 couples and approximately 1 in 25 men. Male factor infertility is a major cause of spermatogenic anomalies, the causes of which are largely unknown. Impaired repro-ductive functions in men might result from physiological, genetic, and/or environmental factors such as xenobiotics. The multi-drug re-sistance1 (MDR1) gene encodes a P-glycoprotein which has a role in the active transport of various substrates providing protection of somatic cells from potentially toxic substances, including xenobi-otics. MDR1 is highly expressed at the luminal surface of capillary endothelial cells, and is expressed in Leydig cells, testicular mac-rophages, and Sertoli cells. We performed genotype and haplotype analyses of MDR1 in 192 infertile and 102 fertile Turkish men for the genetic markers C1236T and C3435T, ...

Sadly, we sometimes see couples where the female has undergone infertility treatment only to learn that there is a male infertility component "missed" by the semen analysis. Sometimes we see couples where the semen analysis was not performed. "Miss diagnosed" male infertility is very frustrating and a waste of time, money, and emotions.. Given the importance of the semen analysis, it must be performed by a highly qualified infertility laboratory with trained andrologists (the study of sperm and semen). Commercial laboratories may perform far fewer analyses than reproductive labs and some personnel do not have advanced training in diagnosing the often subtle causes of male infertility.. ...
Male infertility is most commonly due to problems with sperm; either quantity, motility, or size and shape can impacts ones ability to conceive. One of the most common cause of male infertility is a varicocele, which is found in 40 percent of infertile men. A varicocele is a group of dilated veins in the scrotom. For most men they dont cause any issues and thus require no intervention. Some, however, can experience pain or impaired fertility. The dilated vessels increase the temperature of the scrotum, resulting in testicular damage and impaired sperm production. For that reason, when a couple is having difficulty conceiving and all other causes of an abnormal sperm analysis have been ruled out repair of the varicocele is recommended ...
Low sperm count is the most common reason for male infertility. Structural causes of male infertility include issues with sperm delivery and varicoceles.
The level of nerve growth factor (NGF) in the blood and seminal plasma of asthenozoospermia and oligoasthenozoospermia patients were compared to normozoospermic males and the relationship between NGF with sperm parameters and seminal antioxidant capacity were estimated to determine the role of NGF in the etiology of male infertility. Eighty-one infertile males and 40 normospermic control subjects were included in this stud. NGF levels were measured in the blood and seminal plasma, and its correlation with total antioxidant capacity (TAC), catalase (CAT) and glutathione (GSH) levels and sperm parameters were studied. There was a general trend of decreased in serum and seminal NGF concentrations of asthenozoospermic and oligoasthenozoospermic when compared to the normozoospermic samples. There was no significant association between NGF and seminal antioxidant status in asthenozoospermia and ...
PINA-NETO, J.M. et al. Somatic cytogenetic and azoospermia factor gene microdeletion studies in infertile men. Braz J Med Biol Res [online]. 2006, vol.39, n.4, pp.555-561. ISSN 1414-431X. http://dx.doi.org/10.1590/S0100-879X2006000400017.. The objective of the present study was to determine the frequency of somatic chromosomal anomalies and Y chromosomal microdeletions (azoospermia factor genes, AZF) in infertile males who seek assisted reproduction. These studies are very important because the assisted reproduction techniques (mainly intracytoplasmic sperm injection) bypass the natural selection process and some classical chromosomal abnormalities, microdeletions of AZF genes or some deleterious genic mutations could pass through generations. These genetic abnormalities can cause in the offspring of these patients male infertility, ambiguous external genitalia, mental ...

... occurs when a man cannot produce enough sperm of adequate quality to establish a pregnancy. Sperm are sensitive to temperature changes and the body has evolved means to insure constant testicular temperature. Interestingly, sperm require three months to develop so a semen analysis done today reflects conditions three months prior. This prolonged development period also makes drug treatment of male infertility difficult.. The testicles are contained within the scrotum which expands or contracts in response to temperature. When testicular temperature is "too hot" the scrotum expands to move the testicles away from the body. When the temperature is "too cold" the scrotum contracts bringing the testicles closer to the body. Any activity that interferes with testicular temperature control can lead to decreased fertility.. For example, tight fitting clothes do not allow the scrotum to expand and perform its ...
Intracytoplasmic sperm injection (ICSI) is a process requiring only one single sperm to be injected into each egg. It is considered by many to be the greatest advance for the treatment of male infertility.
Introduction: Y chromosomes are genetically highly variable due to frequent structural rearrangements. The variations may create a genetic background for the susceptibility to Y-related spermatogenic impairment, although few data have been accumulated about the possible correlation between the Y-chromosome haplotype and the predisposition of men to spermatogenic failure.. Objective: To investigate the possible association of Y-chromosome background with spermatogenic failure.. Methods: The distribution of 18 Y-chromosome haplogroups was compared between 414 infertile men with azoospermia or oligozoospermia and 262 normozoospermic men with or without AZFc deletions in a Han population of Southwest China.. Results: A significant population difference in Y-haplogroup distribution was found between the groups of normozoospermia and azoospemia or oligozoospermia, and between the patient groups with oligozoospermia and azoospermia ...

Although structural autosomal abnormality that effaced on azoospermia/oligospermia patient not cleared on previous study we found numbers of this abnormality in cases with low sperm count. Pericentric inversion of the chromosome 9 usually considered as a normal variable feature of this chromosome in general population, but maybe appears to play some important roles in the infertility development. In the present study, 4 cases were found with pericentric inv(9), in which three patients with 46,XY,inv(9)(p12q13) and a 47,XXY,inv(9)(p11q13) as a variant of KS were oligospermic and azoospermic, respectively. A relationship between infertility and autosomal translocation has been observed among severely-oligo / azoospermic patients. In this study, reciprocal translocation t(16;20), rob(2;21), rob(13;15) and rob(15;21) were detected in oligospermic males, while t(Y;19) did in one azoospermic male. ...
Diagnosis of varicocele is based on physical exam and at least two semen analyses. Scrotal ultrasound may be ordered to document size of the testicles.. Treatment. Treatment of the varicocele should be considered when all of the following conditions are met: 1) the varicocele can be felt on physical examination of the scrotum; 2) the couple has known infertility; 3) the female partner has normal fertility or a potentially treatable cause of infertility; and 4) the male partner has an abnormal semen analysis.. Adult men who have a palpable varicocele and abnormal semen analyses but are not currently attempting to conceive should also be offered varicocele repair.. Young men who have a varicocele and normal semen analyses should be followed with ...
In this large, prospective and well-controlled study of semen quality of annual cohorts of young men from the general population, statistically significant increases in sperm concentration and total sperm counts over the past 15 years were detected. However, it is of concern that these men from the general population in the new millennium had significantly lower sperm concentrations and total sperm counts than recently examined fertile men and men of a historical cohort of male partners of infertile couples. Both sperm concentration and sperm morphology measures according to strict criteria are known to be informative semen measurements for discriminating between fertile and infertile men.41 Therefore, there is reason to be concerned about future fertility of young Danish men. Smaller cross-sectional studies of men from the ...
Background: The L68Q variant of cystatin C is highly amyloidogenic forming aggregates in individuals with HCCAA. Results: Spermatozoa from mice expressing human L68Q cystatin C exhibit fertility defects and increased levels of amyloid. Conclusion: L68Q epididymal fluid containing cystatin C amyloid is harmful for sperm function. Significance: Amyloid in the reproductive tract may contribute to male factor infertility. Hereditary cystatin C amyloid angiopathy is an autosomal dominant disorder in which a variant form of cystatin C (L68Q) readily forms amyloid deposits in cerebral arteries in affected individuals resulting in early death. L68Q protein deposits in human cystatin C amyloid angiopathy patients have also been found in tissues outside of the brain including the testis, suggesting possible effects on fertility. Heterozygous transgenic mice (L68Q) that express the human L68Q variant of cystatin C under the control of the mouse ...
To provide indicators for the likelihood of sperm retrieval in patients undergoing testicular sperm extraction is a major issue in the management of male infertility by TESE. The aim of our study was to determine the impact of different parameters, including testicular histopathology, on sperm retrieval in case of reoperation in patients undergoing testicular sperm extraction. We retrospectively analyzed 486 patients who underwent sperm extraction for intracytoplasmic sperm injection and testicular biopsy. Histology was classified into: normal spermatogenesis; hypospermatogenesis (reduction in the number of normal spermatogenetic cells); maturation arrest (absence of the later stages of spermatogenesis); and Sertoli cell only (absence of germ cells). Semen analysis and serum FSH, LH and testosterone were measured. Four hundred thirty patients had non obstructive azoospermia, 53 severe oligozoospermia and 3 necrozoospermia. ...

Terms oligospermia and oligozoospermia refer to semen with a low concentration of sperm and is a common finding in male infertility. Often semen with a decreased sperm concentration may also show significant abnormalities in sperm morphology and motility (technically oligoasthenoteratozoospermia). There has been interest in replacing the descriptive terms used in semen analysis with more quantitative information. The diagnosis of oligozoospermia is based on one low count in a semen analysis performed on two occasions. For many decades sperm concentrations of less than 20 million sperm/ml were considered low or oligospermic, recently, however, the WHO reassessed sperm criteria and established a lower reference point, less than 15 million sperm/ml, consistent with the 5th percentile for fertile men. Sperm concentrations fluctuate and oligospermia may be temporary or permanent. ...
Assisted Reproductive Technology (ART) is an advanced method used to treat infertility in both men and women. It is important to discuss with the fertility specialist about pros and cons of ART treatment. Most common ART treatments for men are explained below:. Intracytoplasmic Sperm Injection (ICSI). Intracytoplasmic sperm injection (ICSI) can be performed in conjunction with in vitro fertilization (IVF). ICSI may be recommended for men who suffer from sperm disorders such as low sperm count, complete absence of sperm cells in semen, poor sperm motility or abnormal sperm morphology. These disorders prevent sperm from successfully penetrating and fertilizing an egg. ICSI can also be used to treat infertility in men caused by premature ejaculation, erectile dysfunction or if previous attempts ...
Background: AZFc on human Y chromosome has been found to be functionally important in spermatogenesis. Complete AZFc deletion is one of the most frequent causes of male infertility, while roles of partial AZFc deletions (gr/gr deletion and b2/b3 deletion) in spermatogenesis are controversial. Methods: To further study the roles of partial AZFc deletions in spermatogenic impairment and the relationship between complete and partial AZFc deletions, we typed these deletions, did quantitative analysis of DAZ gene copies, and performed Y chromosome haplogrouping in seven pedigrees of complete AZFc deletion carriers, 296 infertile and 280 healthy men in Chinese. Results: Neither gr/gr deletion nor b2/b3 deletion was found to be associated with spermatogenic failure. In one pedigree, we observed that a complete AZFc deletion was derived from gr/gr deletion, suggesting that complete deletions of AZFc can be preceded with partial ...
Cleveland Clinic is one of the first institutions in the United States to offer a clinical fellowship in Male Infertility. We have been training clinical and research fellows in this program for more than 20 years. More than 60 percent of our graduates have gone on to academic positions.. This one-year program (minimum) focuses on the development of clinical excellence in all aspects of male fertility management and basic science techniques in andrology. The clinical fellow will spend the majority of his/her time in the clinic and in the operating room, evaluating and managing patients with infertility problems. There is an opportunity for a second-year or research fellowship for interested candidates.. At the start of the fellowship, the fellow completes a comprehensive microsurgery course given by the Department of Plastic Surgery. In addition, he/she has ...
In this study, the semen analysis results of a fertile population were compared with those from a subfertile population, in order to establish normal cut-off values for the standard semen parameters with the aid of receiver operating characteristic (ROC) curve analysis. The fertile group comprised healthy males (n = 107) without any history of fertility problems, the partners of whom had had a spontaneous pregnancy within one year of unprotected intercourse and were pregnant at the time of the males inclusion into the study. A total of 103 males from couples attending the infertility clinic, and with an initial sperm count of <20 × 106/ml were recruited to form the subfertile population. The best discriminating parameter between the two populations was sperm morphology evaluated according to WHO criteria at a cut-off point of 31% normal spermatozoa. The other cut-off values were at 8% for ...

Routine use of sperm storage started in the 60s for patients who undergo gonadotoxic treatment [12, 13]. More recently, sperm storage has also been proposed to patients presenting a very low sperm count or suspected at high risk of rapid decrease in the sperm count (possibly linked to several genetic origins of the oligozoospermia) and asking for Assisted Reproductive Techniques [13]. This practice was also reinforced in our center by several cases of severe male infertility which led to azoospermia even before the first ICSI had been done. Nevertheless, it is a time consuming practice and only few studies were available so far to evaluate the real benefit for the patients. The first important one was by Lahav-Baratz et al and described the interest of sperm pooling and cryopreservation before the ICSI [8].. When comparing our sperm storage data to the literature, we see that the amount of samples per patient is not different from those ...
A varicocele is a dilatation of the veins of the pampiniform (venous) plexus in the spermatic cord in the male. It is a very common finding in infertile men being associated with 15% of men with primary infertility and 80% of men with secondary infertility. Though varicocele repair in infertility has always been a point of semantics, it has been proven that repair can improve pregnancy rates. Azoospermia due to testicular failure is classified as non obstructive Azoospermia (NOA) and the tteatment usually entails testicular sperm extraction(TESE) with ICSI. Though varicocelectomy can produce motile sperm in these patients the benefits remain unclear.. Various researchers have been studying the effects of Microsurgical varicocelectomy in NOA patients. Most findings concluded that if Azoospermia is not too long standing, then ...
Various hormones have been studied as regards prediction of pregnancy outcome after infertility treatment, but no ideal candidate has been found. Folate and genetic variations in folate metabolism have also been associated with infertility, but it remains unclear how these factors affect IVF pregnancy outcome. It is known that infertility is associated with active folic acid supplement use, but the effect of socioeconomic and lifestyle factors on folic acid supplement use in infertile women has not been well investigated. The overall aim of this work was to obtain information on the prediction of live birth, and to study factors affecting the role of folate and folic acid intake in relation to IVF pregnancy outcome. Infertile women with various ...
Infertility cases which involve only the male partner amount to 20% of the causes for infertility. Male infertility causes are broadly categorized as: impaired production of the sperm and impaired delivery of sperm. Impaired production of sperm is because of low sperm count, impaired shape and the movement of the sperm, varicocele, testosterone deficiency, genetic defects, infections and undescended testicles. Impaired delivery of sperm is due to cystic fibrosis, presence of anti-sperm antibodies, hypospadias, blockage of ejaculatory ducts or blockage of epididymis, retrograde ejaculation and other sexual issues.

article{7cc3097b-22b4-448a-9bce-4c18189ec61f, abstract = {BACKGROUND: The sperm chromatin structure assay (SCSA) provides an objective assessment of sperm chromatin integrity, which is essential for normal sperm function. SCSA is valuable as a fertility marker in epidemiological studies and in the clinical situation. Little is known about the impact of testicular and post-testicular function on SCSA parameters. METHODS: Ejaculates from 278 military conscripts of median age 18.1 (range 18-21) years were included. Levels of reproductive hormones, the length of the CAG repeat of the androgen receptor gene, sperm concentration, abstinence period and biochemical parameters of epididymal and accessory sex gland secretions were correlated to the SCSA parameters, DNA fragmentation index (DFI) and highly DNA stainable (HDS) cells. RESULTS: Negative correlations were found between sperm concentration and DFI (r = -0.119, P = 0.049) and HDS (r = -0.513, P < 0.0001). DFI was ...
This is a very large retrospective review from a single andrology lab studying the impact of BMI on semen parameters with ,10,000 infertile subjects - one of the largest studies to date. The findings demonstrate the impact of obesity on semen analysis and subsequently fertility status. As BMI increased, there was a statistically significant decline in volume, concentration, count, viability, and progressive motility. Interestingly, morphology was not different. There were no comments on medical conditions of the subjects (ie hypogonadism, varicocele, diabetes, hypothyroid/hyperthyroid, medications taken, etc.) It would be interesting to see if the BMI effects on semen analysis would be the same for fertile men divided into respective BMI categories in this study.. ...
Numerous reports have suggested that disturbances in nuclear condensation may result in male infertility. This notion has been supported by the observation of infertile individuals with a decrease or absence of the male sperm-specific chromatin packaging protamine proteins. To date, no correlation between the absence of protamine proteins and a mutation within the coding regions of the protamine genes has been documented. To address this issue, PCR-based mutation scanning analysis has been performed across the human male haploid expressed PRM1--|PRM2--|TNP2 domain in several oligozoospermic infertile individuals. This analysis identified a candidate mutation in a region of contact with the sperm nuclear matrix from 2 of 5 affected individuals. This is the first report of a mutation scan covering the entire PRM1--|PRM2--|TNP2 locus in affected individuals.
Introduction: Currently, there exists no serum biomarker to predict patients likely to benefit from varicocelectomy. The purpose of this study was to assess the association between baseline follicle-stimulating hormone (FSH) and semen parameter changes after subinguinal microscopic varicocelectomy.. Methods: We retrospectively reviewed all men who underwent microscopic subinguinal varicocelectomy between August 2015 and October 2018. Pre- and postoperative semen analyses were stratified per total motile sperm count (TMSC): TMSC ,5, 5-9, and ,9 million (based on TMSC required for in vitro fertilization, intrauterine insemination [IUI], and natural conception, respectively). Then, variables were analyzed to determine the correlation with postoperative TMSC values and upgrade in TMSC category.. Results: Among the 66 men analyzed, 55 (83.3%) and 11 (16.7%) had a preoperative TMSC of ,5 million and 5-9 million, respectively. A total of 33 (50%) ...
When conception does not occur after one year of unprotected intercourse, after six months in women over age 35, or if there are known problems causing infertility, a medical evaluation of both the male and female is recommended. Some obstetrician/gynecologists (OB/GYNs), certified nurse midwives (CNMs), and nurse practitioners (NPs) are able to provide basic infertility evaluation and treatment. However, many causes of infertility are best treated by a board-certified reproductive endocrinologist. This is an OB/GYN who has had additional education and training in infertility and is certified with the American Board of Obstetrics and Gynecology in the sub-specialty of Reproductive Endocrinology and Infertility.. Generally, the OB/GYN or reproductive ...

Egg infertility is a predisposition to miscarriages, infertility, and trisomic pregnancies caused by increased frequency of chromosome segregation errors in the eggs of women of advanced maternal age (AMA). Egg infertility is now a significant public health issue, with 1 in 5 US women now attempting her first pregnancy after age 35. Increased rates of egg infertility temporally coincide with rising levels of FSH that occur with age. By age 42, up to 87% of embryos are aneuploid, and 40-50% of women experience egg infertility. An Introductory Editorial will present an overview of causative factors and potential therapeutic strategies to prevent egg aneuploidy and infertility. Papers in series will be comprised of data drawn from studies ...
Even relatively minor errors in chromatin remodeling during spermiogenesis are associated with sperm DNA damage and infertility, yet little is known about the etiology. Mice with severe NPYq deletions are infertile due to severe sperm differentiation defects (Ward and Burgoyne, 2006; Yamauchi et al., 2009). We have recently observed that sperm from these mice presented abnormal chromatin packaging and DNA damage. Moreover, when these sperm were injected into the oocytes, a significant increase of oocyte arrest at pronuclei stage and of chromosome aberrations in the fertilized eggs were noted (Yamauchi et al., 2010). Here we provide evidence that the deficiency of NPYq encoded gene Sly is associated with sperm DNA damage and poor sperm chromatin condensation, and propose that SLY plays a role in spermatid-specific chromatin remodeling.. How can Sly/SLY be involved in sperm DNA damage phenotype? SLY protein has been shown to control the postmeiotic expression of ,100 genes, ...
Anovulatory cycles and endometriosis are the main causes of female infertility. The most frequently anovulatory cycles are related to polycystic ovary syndrome (PCOS) commonly associated with obesity and hormonal disturbances in the course of obesity. Recently published studies revealed that infertility affects about one in six couples during their lifetime and is more frequent in obese. Obesity is also associated with male infertility related to erectile dysfunction, hormonal disturbances and lower semen quality. Any of these above mentioned disorder is the important risk factor of psychological disturbances and poor quality of life among women and men in the reproductive age. On the other hand the mood disorders may exacerbate the hormonal disturbances and worsen the effectiveness of ...

In Vitro Fertilization (IVF) and embryo transfer. In Vitro Fertilization (IVF) is one of the most effective ART treatments. In IVF, fertilization of multiple eggs by sperm take place in a laboratory setting and one or more embryos formed are then transplanted into mothers womb (uterus). This method is used to treat infertility in women suffering from damaged or blocked fallopian tubes, cervical mucus defect, endometriosis, ovulatory disorders, sperm allergy or unexplained infertility. IVF is also used to treat infertility caused by male factors such as sperm disorders, blocks in vas deferens or ejaculatory duct, ...
Sperm morphology, shape of sperm, is important to a successful IVF cycle. A Semen Analysis report with abnormal sperm morphology may point to IVF with ICSI
A low sperm count, or in scientific terms oligospermia/ azoospermia, refers to a condition where the concentration of sperm in ejaculated semen is below normal or not existing. That begs the question - What is normal sperm concentration supposed to be? World Health Organization (WHO), acclaims that concentration of ,15 million sperm/ml is a low sperm count. If there appears to be no sperm in the sperm analysis it is called azoospermia.. ...
The association between semen quality and male infertility has been known for more than 40 years.. Having reviewed the literature, it seems clear that strict morphology has a clinical relevance, being an excellent biomarker of sperm fertilizing capacity, in vivo and in vitro, independent of motility and concentration (27).. Sperm morphology evaluation is considered to be a highly subjective procedure because, unlike the haematopoietic cells for example, the difficulty in classifying human sperm morphology is caused by the large variety of abnormal forms found in the semen of infertile and fertile men. Only certain types of abnormality can be quantitated objectively (11).. Normal sperm morphology needs to consider two points. The first one is the proportion of spermatozoa with normal morphology in semen and the second is the definition and the characterization of the normal spermatozoa.. ...

Men who undergo vasectomy reversal and have low testosterone should not be treated with testosterone replacement, as it will suppress sperm production. There is no clear answer in the scientific research on whether Clomiphene Citrate, a commonly used medication to treat low testosterone in men who want to maintain fertility potential in a way that is not detrimental for sperm, actually improves semen parameters on not. Some research have shown some improvement in some semen parameters, and other studies have shown no impact. At the 2017 American Society for Reproductive Medicine annual expo and scientific meeting, Dr. Kavoussis research was presented on factors that might potentially predict which patients may respond to Clomiphene Citrate with an improvement in semen parameters. Ultimately, the data showed no significant difference in sperm ...
Congenital bilateral absence of vas deferens (CBAVD)is diagnosed in 1.3 % of the men referred for infertility evaluation. Moreover, CBAVD accounts for 27% of the men with primary obstructive azoospermia. An almost equal number of men with other causes of surgically unreconstructable obstructive azoospermia are referred for evaluation.
According to the National Institute of Mental Health, depressive disorders afflict over six million U.S. men annually. Most cases of moderate or severe depression are treated with antidepressants, including monoamine oxidase inhibitors, tricyclic antidepressants, and, more recently, selective serotonin reuptake inhibitors (SSRIs) and antidepressants with modest serotonin and norepinephrine reuptake inhibition but unknown mechanism-of-action. Over the past two years, prescribing data show a steady increase in antidepressant dispensing rates (especially including serotonin reuptake inhibitors) for adults. SSRIs are known to have an effect on ejaculatory function and are therapeutically used for treatment of premature (rapid) ejaculation. However, few studies have evaluated the potential impact of antidepressant medications on male fertility, and no studies have been published with respect to the impact of newer antidepressants, such as SSRIs, ...

The objective of the present longitudinal descriptive study was to extend previous observations on the benefit of in-vitro fertilization (IVF) in cases of anejaculatory infertility due to spinal cord injuries (SCI) and to report results achieved by intracytoplasmic sperm injection (ICSI). The study was performed in a national referral unit for SCI, Spinalis SCI Research Unit, the Karolinska Institute. The patient material consisted of couples with SCI men seeking treatment for their infertility. The inclusion criteria were: stable relationship, motile spermatozoa in a diagnostic sample and no female contraindications. Spermatozoa were retrieved through electroejaculation or vibratory stimulation. If the sperm quality was judged to be sufficient, standard IVF was performed. ICSI was employed if the semen quality was extremely poor. We have treated 25 couples in 52 cycles, ...
Azoospermia is the medical term used for nil sperm count or absent of sperm. It is the major cause of male infertility and should be treated immediately.

Background: Some medicinal plants with their antioxidant properties have protective effects on sperm parameters and neutralize the harmful effects of lead exposure. Objectives: The present study aimed to determine the effects of Melissa on sperm parameters and spermatogenesis quality in adult rats exposed to lead. Methods: This animal experimental study was conducted on 45 male Wistar rats weighing 180 ± 20 g, which were allocated randomly into five groups (n=9): distilled water gavages (control) (0.5 ml); intraperitoneal distilled water (i.p. control) (0.5 ml); Melissa (100 mg/kg/bw); lead acetate (10 mg/kg/bw); and lead acetate (10 mg/kg/bw) plus Melissa (100 mg/kg/bw). After a 30-day treatment, the animals were sacrificed. Sperm parameters (count, motility, morphology, and chromatins assay) and weighing of the epididymis and testis were performed. Results: The results showed that in the lead acetate plus Melissa group, epididymis weight (0.37gr vs. ...
Azoospermia factor (AZF) refers to one of several proteins or their genes, which are coded from the AZF region on the human male Y chromosome. Deletions in this region are associated with inability to produce sperm. Subregions within the AZF region are AZFa (sometimes AZF1), AZFb and AZFc (together referred to as AZF2). AZF is the term used by the HUGO Gene Nomenclature Committee. AZF1 (Azoospermia Factor 1) gene is likely located in the euchromatic part of the long arm in Yq11.23. AZF1 is 792kb long and just distal to the centromere of the Y chromosome. AZF1 genes are involved in spermatogenesis in the testes. Originally, an AZFb and AZFc genes were identified and thought to be separate regions. They were later found to be overlapping and are now referred to as AZF2. AZFc is one of the most genetically dynamic regions in the human genome, possibly serving as counter against the genetic degeneracy associated with the lack of a partner ...

132 male partners were normozoospermic with count , 20X106 sperm per ml, ,50% motile with forward progression (categories a and b) within 60 min of ejaculation and , 60% morphologically normal spermatozoa (WHO criteria) [7]. Male partners with sperm count ranging from 10X106 to 20X106 were asked to produce a second semen sample within 2 hours of the first sample on the day of insemination. Sixty-eight males having sub fertility as per WHO criteria did consent to the study. However 04 could not produce a second sample at the time of IUI, and 1 patient had total sperm immotility and was excluded from the study. A fresh ejaculate was delivered in a sterile 60 ml jar by masturbation on the day of insemination. Neat semen was left at room temperature for liquefaction for 30 minutes.The liquefied semen samples were analyzed for density and motility using a fixed-depth counting chamber (Makler). The liquefied ...
What is Surgical Sperm Retrieval?. This is a treatment option for men with Azoospermia (absence of sperm in the ejaculate) due to obstruction or poor production (non-obstructive).. Sperm can be collected directly from the epididymis where sperm are usually stored and matured. The sperm can be collected using a fine needle and syringe. This is known as (percutaneous epididymal sperm aspiration) or PESA. Sperm can also be retrieved from the testicles, a procedure known as (testicular sperm extraction) or TESE.. Surgical sperm retrieval is carried out by an experienced surgeon, usually a Consultant Uroandrologist, or a fertility specialist. The procedure needs to be timed to coincide with the female partners egg collection. If enough sperm is retrieved, it may be possible to freeze small amounts for use at a later stage. The sperm collected is then used to inject the eggs using ICSI.. ...

There are two methods for performing sperm morphological evaluations during a semen analysis. Most clinical laboratories perform a crude estimation of the percentage of sperm in the ejaculated specimen that appear to have normal shape. Only specialized andrology laboratories have trained technicians that can perform a strict sperm morphological evaluation during a semen analysis. Only these strict criteria (also known as Krueger criteria) have been studied with regard to fertilization success or failure. If a man has a decreased number of normally shaped sperm on the Krueger strict morphology analysis, he is at risk of fertilization failure or at least low rates of fertilization. However, an increased number of abnormally shaped sperm with non-strict criteria may indicate a fertilization problem, but to be certain this test should probably be repeated in a laboratory that performs strict criteria semen analysis. Strict morphology is a useful ...
Introduction. Low ovarian response to stimulation protocol in intracytoplasmic sperm injection (ICSI) is frustrating to physicians and patients especially when the initial evaluation seems to be fair. Regarding this emerging problem, different measures usually taken trying to rescue the cycle and avoid cancelation. It was estimated that about 9-18% of cycles result in this low response with small number of follicles and low estradiol level.1. The term "poor responder" has been used to determine women who require large doses of stimulation medications and who make less than an optimal number of eggs. The definition of low responders differs from center to other, but the most used one is that less than four dominant follicles on day of human chorionic gonadotropin (hCG) administration.2. The occurrence of low response to ovarian stimulation is usually suspected in old age, although it could occur at any age. Ovarian reserve is the main factor affecting response to stimulation, ...
There are many fertility clinic options in New York city and surrounding boroughs. Choosing one may seem rather difficult. One way to begin comparing the fertility clinics is to look at their success rates. Fertility clinic success rates for New York City fertility clinics, as well as for clinics across the United States, can be found in the Assisted Reproductive Technology (ART) Report. The ART Report, which is compiled by the CDC, lists success rates for every fertility clinic in the United States for IVF procedures using fresh and frozen non-donor eggs, and fresh and frozen donor eggs. The success rates for non-donor egg IVF cycles are broken out by age group.
The metabolic syndrome (MetS) is a collection of various metabolic, hormonal and immunological risk factors that cluster together, closely related to poorly understood phenomena such a hyperinsulinaemia (insulin resistance), hyperleptinaemia (leptin resistance), a low grade, systemic and chronic inflammation and, in males, hypogonadism. Infertility is increasing globally, and male factor infertility accounts for a large percentage of couples who are not able to conceive. The relationship between components of MetS and male reproductive health is not clear, and requires further investigation, as does the impact of MetS on male reproductive health in a case controlled study. The impact of hyperinsulinaemia, hyperleptinaemia and inflammatory cytokines on the male reproductive tract also requires investigation. ...
Background: Varicocele therapy is a controversial issue. No single approach is adopted as the best therapeutic option. Testes get blood supply from testicular artery, cremasteric artery and artery to the vas deference. So ligation of testicular artery in the abdomen do not cause ischemia to the testis. This was already demonstrated in many studies. Classical Palomo varicocelectomy also consists of open ligation of testicular vessels in the retroperitoneum. En mass ligation of testicular vein and artery is technically easy and fast in laparoscopic varicocelectomy (LV). Chance of missing some veins are also less. Henceforth recurrence is also less. Recurrence and post-operative complications are high when only testicular vein is ligated by laparoscopy in the retroperitoneum. We wanted to see the outcome of laparoscopic varicocelectomy by mass ligation technique.. Methods: 56 patients of symptomatic varicoceles were included in the study from the outpatient services. Symptomatic varicoceles of ...

MATERIALS AND METHODS: Sixty male rats were divided into five experimental groups: a normal control group (CTR + vehicle), a control group administered MOTILIPERM 200 mg/kg (CTR + M 200), a varicocele-induced control group (VC + vehicle) and two varicocele-induced groups administered MOTILIPERM 100 (VC + M 100) or 200 (VC + M 200) mg/kg for 4 weeks ...
Sperm concentration, total number and viability. The major part of the ejaculate volume is contributed by secretions from the accessory glands (seminal vesicles and prostate), so the ejaculate volume is not directly related to spermatogenesis and hence the sperm cell concentration (sperm cells/ml) varies according to the ejaculate volume. The total number of spermatozoa per ejaculate reflects the spermatogenesis and is related to the time of sexual abstinence before collection. In normal situation spermatogenesis is considered to be a constant process over time and therefore the total number of sperm per ejaculate should increase with abstinence time. The ejaculate volume is related to the secretory function of the seminal vesicles and prostate. Decreased ejaculate volume and increased sperm concentration reflects impaired accessory glands function. Vital staining of the spermatozoa allows to quantitate the fraction of living cells independently from their motility.. Spermatozoa motility. The ...
Sperm antibodies are present in 6% of infertile men. They have sperm coated with antibodies to the extent that sperm function is impaired, particularly sperm-mucus penetration and sperm-zona pellucida binding, resulting in severe infertility.. Natural pregnancy rates without treatment are very low, and fertilization rates with standard IVF are low or zero. Other men have positive Antibodies test, sometimes with tail tip-only binding and normal or only marginally impaired mucus penetration. These low-level sperm antibodies are probably irrelevant to the infertility, and other causes of the couples infertility should be sought. Sperm antibodies can be treated by steroids in immunosuppressive doses. Antibody levels fall, and semen quality improves in about 50% of patients; about 25% produce natural conceptions during a 4- to 6-month course of ...
A recent meta-analysis by Levine and colleagues1 showing significant declines in sperm counts among men in the Western world caught considerable media attention.2 The Levine study followed a similar report in The BMJ 25 years ago.3 Should we be concerned? Is male reproductive health really at risk?. Meta-analyses have some inherent limitations. However, an important and often overlooked point about data on the quality of semen is that trend data should be interpreted with a holistic view of male reproductive health problems, including parallel trends in testicular germ cell cancer (TGCC). Incidence of this cancer has risen substantially over the past few decades, particularly in young men.4 Increases seem to be occurring even in countries that have had low incidence. TGCC is linked to risk of poor semen quality: reports suggest that countries with a high incidence of … ...
