Male infertilityUnexplained infertility: Unexplained infertility is infertility that is idiopathic in the sense that its cause remains unknown even after an infertility work-up, usually including semen analysis in the man and assessment of ovulation and fallopian tubes in the woman.merckmanuals > Unexplained Infertility Last full review/revision November 2008 by Robert W.Low Fertility Cohorts Study: The Low Fertility Cohorts Study, 1978: A Survey of White, Ever-Married Women Belonging to the 1901-1910 United States Birth Cohorts,Data Sharing For Demographic Research consists of personal interviews of white, ever-married women born between July 1, 1900, and June 30, 1910. In 1978, a national survey of 1,049 married women between the ages of 68 and 78 were interviewed between the months of March and July in order to investigate low fertility during the 1920s and 1930s and the women of childbearing age during those decades.Endosalpingiosis: In gynecology, endosalpingiosis is a condition in which fallopian tube-like epithelium is found outside of the fallopian tube. It is unknown what causes this condition.Spermiogenesis: Spermiogenesis is the final stage of spermatogenesis, which sees the maturation of spermatids into mature, motile spermatozoa. The spermatid is more or less circular cell containing a nucleus, Golgi apparatus, centriole and mitochondria.Prenatal nutrition: Nutrition and weight management before and during :pregnancy has a profound effect on the development of infants. This is a rather critical time for healthy fetal development as infants rely heavily on maternal stores and nutrient for optimal growth and health outcome later in life.AzoospermiaNatural cycle in vitro fertilization: Natural Cycle IVF is in vitro fertilisation (IVF) using either of the following procedures:Sperm: Sperm is the male reproductive cell and is derived from the Greek word (σπέρμα) sperma (meaning "seed"). In the types of sexual reproduction known as anisogamy and its subtype oogamy, there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell.FNA Mapping: Fine needle aspiration (FNA) cytology has been used to examine pathological human tissue from various organs for over 100 years.,Posner C.Hyperactivation: Hyperactivation is a type of sperm motility. Hyperactivated sperm motility is characterised by a high amplitude, asymmetrical beating pattern of the sperm tail (flagellum).EndometriosisHysterosalpingographyVaricoceleSemen quality: Semen quality is a measure of the ability of semen to accomplish fertilization. Thus, it is a measure of fertility in a man.Pregnancy rate: Pregnancy rate is the success rate for getting pregnant. It is the percentage of all attempts that leads to pregnancy, with attempts generally referring to menstrual cycles where insemination or any artificial equivalent is used, which may be simple artificial insemination (AI) or AI with additional in vitro fertilization.Isodemis: Isodemis is a genus of moths belonging to the subfamily Tortricinae of the family Tortricidae.Blood–testis barrier: The blood–testis barrier is a physical barrier between the blood vessels and the seminiferous tubules of the animal testes. The name "blood-testis barrier" is misleading in that it is not a blood-organ barrier in a strict sense, but is formed between Sertoli cells of the seminiferous tubule and as such isolates the further developed stages of germ cells from the blood.AnovulationReproductive technology: Reproductive technology (RT) encompasses all current and anticipated uses of technology in human and animal reproduction, including assisted reproductive technology, contraception and others.Reproductive toxicity: Reproductive toxicity is a hazard associated with some chemical substances, that they will interfere in some way with normal reproduction; such substances are called reprotoxic. It includes adverse effects on sexual function and fertility in adult males and females, as well as developmental toxicity in the offspring.Sexual motivation and hormones: Sexual motivation is influenced by hormones such as testosterone, estrogen, progesterone, oxytocin, and vasopressin. In most mammalian species, sex hormones control the ability to engage in sexual behaviours.Embryo transfer: Embryo transfer refers to a step in the process of assisted reproduction in which embryos are placed into the uterus of a female with the intent to establish a pregnancy. This technique (which is often used in connection with in vitro fertilization (IVF)), may be used in humans or in animals, in which situations the goals may vary.Fallopian tube obstructionPCDHY: PCDH11Y is a gene unique to human males which competes with FOXP2 for the title of the "language gene." PCDH11Y is the gene for making Protocadherin 11Y, a protein that guides the development of nerve cells.Uterus transplantation: The uterine transplant is the surgical procedure whereby a healthy uterus is transplanted into a female organism of which the uterus is absent or diseased. As part of normal mammalian sexual reproduction, a diseased or absent uterus does not allow normal embryonic implantation, effectively rendering the female infertile.CAP protein family: In molecular biology, the CAP protein family (cysteine-rich secretory proteins, antigen 5, and pathogenesis-related 1 proteins (CAP)) is a large family of proteins that are found in a wide range of organisms, including prokaryotes and non-vertebrate eukaryotes. The nine subfamilies of the mammalian CAP 'super'family include: the human glioma pathogenesis-related 1 (GLIPR1), Golgi associated pathogenesis related-1 (GAPR1) proteins, peptidase inhibitor 15 (PI15), peptidase inhibitor 16 (PI16), cysteine-rich secretory proteins (CRISPs), CRISP LCCL domain containing 1 (CRISPLD1), CRISP LCCL domain containing 2 (CRISPLD2), mannose receptor like and the R3H domain containing like proteins.OrchitisFitz-Hugh–Curtis syndromePrimary ovarian insufficiency: Primary Ovarian Insufficiency (POI), formerly known as premature ovarian failure, is defined as the cessation of normal ovarian function before age 40 years. It is the scientifically accurate term for the condition that was previously referred to as premature menopause or premature ovarian failure.Infertility in polycystic ovary syndrome: Polycystic ovary disease (PCOS) is a hormonal imbalance in women that is thought to be one of the leading causes of female infertility.Palacio JR et,al.Chlamydia antibodies: Chlamydia antibodies are antibodies targeting bacteria of the Chlamydia genus, but it generally refers specifically to antibodies targeting Chlamydia trachomatis, which is the cause of Chlamydia infection in humans.Oocyte selection: Oocyte selection is a procedure that is performed prior to in vitro fertilization, in order to use oocytes with maximal chances of resulting in pregnancy. In contrast, embryo selection takes place after fertilization.Endometrium: The endometrium is the inner mucous membrane of the mammalian uterus.Orchialgia: Orchialgia is long-term pain of the testes. It is considered chronic if it has persisted for more than 3 months.Ovarian diseaseGenitourinary medicine: Genitourinary medicine is a portmanteau that includes aspects of andrology, gynecology and urology. It is primarily related to medicine dealing with sexually transmitted diseases.QRISK: QRISK2 (the most recent version of QRISK) is a prediction algorithm for cardiovascular disease (CVD) that uses traditional risk factors (age, systolic blood pressure, smoking status and ratio of total serum cholesterol to high-density lipoprotein cholesterol) together with body mass index, ethnicity, measures of deprivation, family history, chronic kidney disease, rheumatoid arthritis, atrial fibrillation, diabetes mellitus, and antihypertensive treatment.Chlamydia trachomatisEstradiol cypionate: Estradiol cypionate (INN, USAN) (brand names Depo-Estradiol, Depofemin, Estradep, and many others), or estradiol cipionate, is a synthetic ester, specifically the 3-cyclopentylpropanoyl ester, of the natural estrogen, estradiol. It was first introduced in 1952 by Upjohn in the United States, and has been in widespread use since.Canga's bead symptom: In radiology, Canga's bead symptom is the irregular appearance of uterus and nodular structures in tuba uterina observed in patients with genital tuberculosis.Canga, S: Kadýn Hastalýklarý Jinekoloji.Epididymis: The epididymis (; plural: epididymides or ) is a tube that connects a testicle to a vas deferens in the male reproductive system. It is present in all male reptiles, birds, and mammals.Female genital diseaseNested case-control study: A nested case control (NCC) study is a variation of a case-control study in which only a subset of controls from the cohort are compared to the incident cases. In a case-cohort study, all incident cases in the cohort are compared to a random subset of participants who do not develop the disease of interest.Prenatal testosterone transfer: Prenatal Testosterone Transfer (also known as prenatal androgen transfer or prenatal hormone transfer) refers to the phenomenon in which testosterone synthesized by a developing male fetus transfers to one or more developing fetuses within the womb and influences development. This typically results in the partial masculinization of specific aspects of female behavior, cognition, and morphology, though some studies have found that testosterone transfer can cause an exaggerated masculinization in males.Temporal analysis of products: Temporal Analysis of Products (TAP), (TAP-2), (TAP-3) is an experimental technique for studyingXueren: Xueren (English: The ScholarThe Scholar was the translation preferred by the editors of Xueren, appearing thus in their journal, but the title is sometimes also translated Scholars.) was an influential Chinese independent intellectual journal that ran from 1991 to 2000.Age adjustment: In epidemiology and demography, age adjustment, also called age standardization, is a technique used to allow populations to be compared when the age profiles of the populations are quite different.Gursaran Talwar: Gursaran Prasad Talwar is a medical researcher working in the area of vaccines and immunocontraception. In a 1994 paper, his group demonstrated that women could be vaccinated to prevent pregnancy.Retrograde ejaculationMercian Way: The Mercian Way is a long cycle path that runs from Salisbury in Wiltshire to Chester in Cheshire. Operated by Sustrans, it is part of National Cycle Route 45, but is also well used by walkers.Hyalobarrier: Hyalobarrier is a substance to keep tissue apart post surgery and therefore prevent adhesions. It contains autocross-linked hyaluronan.Sertoli cell nodule: A Sertoli cell nodule, also Pick's adenoma, testicular tubular adenoma and tubular adenoma of the testis, is a benign proliferation of Sertoli cells that arises in association with cryptorchidism (undescended testis). They are not composed of a clonal cell population, i.Screening of potential sperm bank donors: In sperm banks, screening of potential sperm donors typically includes genetic diseases, chromosomal abnormalities and sexually transmitted infections that may be transmitted through sperm. The screening procedure generally also includes a quarantine period, in which the samples are frozen and stored for at least 6 months after which the donor will be re-tested for the STIs.Ovarian tissue cryopreservation: Ovarian tissue cryopreservation is cryopreservation of tissue of the ovary of a female.Closed-ended question: A closed-ended question is a question format that limits respondents with a list of answer choices from which they must choose to answer the question.Dillman D.Postcoital test: The postcoital test (PCT) (also known as Sims test, Huhner test or Sims-Huhner test) is a test in the evaluation of infertility. The test examines interaction between sperm and mucus of the cervix.ClomifeneVaginal septumJean-Baptiste-Maximien Parchappe de Vinay: Jean-Baptiste-Maximien Parchappe de Vinay (October 21, 1800 – March 12, 1866) was a French psychiatrist who was a native of Épernay, Marne.
