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 retardation, and other birth defects. We studied 165 infertile men whose infertility was attributable to testicular problems (60 ...

Complex Chromosomal Rearrangements (CCRs) are rare structural abnormalities that are usually associated with infertility or subfertility in male carriers. We described clinical and chromosomal features of a non-obstructive azoospermic male that has been referred for infertility. Cytogenetic analysis showed three chromosomes, i.e. 3, 8 and 16, which have been involved and caused spermatogenesis failure ...

It is a simple, minimal invasive procedure that allows the clinician to gain information regarding spermatogenesis..

It helps in differentiating between obstructive and non obstructive azoospermia. Testicular biopsy can provide a definitive diagnosis of non obstructive azoospermia.. Non obstructive azoospermia present with abnormal spermatogenesis.. It can be used to retrieve sperm in men with azoospermia. It can be performed under local or general anesthesia.. ...

Spermatogenesis and oogenesis specific basic helix-loop-helix 1 (SOHLH1) and spermatogenesis and oogenesis specific basic helix-loop-helix 2 (SOHLH2) play essential roles for both spermatogenesis and oogenesis. The aim of this study was to evaluate the association of SOHLH1 and SOHLH2 single nucleotide polymorphisms (SNPs) with non-obstructive azoospermia (NOA) in the Chinese population. In this study, we assessed 7 single nucleotide polymorphisms (SNPs) of SOHLH1 and SOHLH2 with Sequenom iplex technology in 361 NOA cases and 368 fertile controls. We found that the SNPs rs1328626 and rs6563386 of SOHLH2 were significantly associated with NOA risk, of which, a protective effect of minor allele T of rs1328626 on NOA (P = 0.038, odds ratio [OR] = 0.799, 95% confidence interval [CI] = 0.645-0.988) and a significantly increased risk of the SNP rs6563386 with the minor allele G to NOA (P = 0.029, OR = 1.402, 95% CI = 1.034-1.9) were observed, respectively. Our data indicated that the haplotype GC of ...

Distinction between obstructive and non-obstructive azoospermiaPrior to initiating treatment for a couple, in whom the man has azoospermia, it is important to distinguish whether the lack of sperm in the ejaculate is from an obstructive or non-obstructive process. In addition, careful evaluation of the post-ejaculate urinalysis is necessary to rule out retrograde ejaculation, common in diabetics.

Round spermatid injection (ROSI) is a technique of assisted reproduction whereby a round spermatid is injected into oocyte cytoplasm in order to achieve fertilization. This technique can be used to enable genetic fatherhood to some men who have no spermatozoa in the ejaculate (azoospermia) and in whom spermatozoa cannot be obtained surgically from the testicles. This condition is called nonobstructive or secretory azoospermia, as opposed to obstructive azoospermia, in which complete sperm production does occur in the testicles, and potentially fertilizing spermatozoa can be obtained by testicular sperm extraction (TESE) and used for ICSI. In cases of nonobstructive (secretory) azoospermia, on the other hand, testicular sperm production is blocked at different stages of the process of sperm formation (spermatogenesis). In those men in whom spermatogenesis is blocked at the stage of round spermatids, in which meiosis has already been completed, these round cells can successfully fertilize oocytes ...

A cohort study of 2,238 men who were evaluated for infertility at a clinic in Texas from 1989 to 2009 found that those men who had azoospermia, a condition in which no measurable sperm is present, had a 2.2-fold higher cancer risk compared with those who were nonazoospermic. The study was published online in the journal Fertility and Sterility.1. Study Details. In all, 451 men had azoospermia and 1,787 were not azoospermic (mean age at evaluation = 35.7 years). The researchers found 29 cases of cancer, including testicular, prostate, and intestinal cancers, as well as lymphoma and melanoma, during an average follow-up of nearly 7 years.. The standardized incidence rate of cancer among infertile men was 1.7 times that of the general population, and when stratified by azoospermic status, men with azoospermia had substantially elevated risk of cancer (standardized incidence rate = 2.9). In contrast, men without azoospermia had an increased risk of 1.4 times that of men in the overall ...

N2 - Purpose: We determined the effect of prior biopsies with no sperm seen on the chance of sperm retrieval with microdissection testicular sperm extraction in men with nonobstructive azoospermia. Materials and Methods: A total of 311 men with NOA underwent microdissection testicular sperm extraction. Of these patients 135 underwent no prior biopsies, 159 underwent 1 or 2 diagnostic testicular biopsies per testis and 17 underwent 3 or 4. The outcome measure studied was the success of sperm retrieval with microdissection testicular sperm extraction. Serum follicle-stimulating hormone and histopathological diagnosis were examined as predictive factors for sperm recovery. Results: Spermatozoa were retrieved in 150 men by microdissection testicular sperm extraction (48%). The success of sperm retrieval in ...

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 the effects of Varicocelectomy may produce motile sperm and also may reduce the need for a TESE during an ICSI procedure. It is important to note that none of these ...

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. There were 307 (63%) successful sperm retrieval. Higher testicular volume, lower

Azoospermia is a medical condition faced by men in which there is complete lack of sperm in semen resulting in a situation where a couple cannot conceive a child. It is a very frustratiing problem and can lead to other ailments like depression. There are many reasons which can cause azoospermia but it has no symptoms associated with it. A man can only find out if he is suffering from azoospermia when he cannot conceive a child and goes through a fertility test.. The good thing is that once it is ascertained that a person is suffering from no sperm count he can take help and overcome this problem. In this article we are going to discuss about how natural form of treatment can help in producing sperms and treating azoospermia.. It has been observed that this condition is mainly the result of hormonal imbalance in the body hence natural form of treatment can be of great help as they help in substituting the male hormones and bring them to normal levels. By doing this the natural medicine will ...

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 chromosome during meiosis. However, such strategy comes has ...

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 without AZFc deletions. Interpopulation comparison of Y haplogroup ...

The genetic basis of male infertility remains unclear in the majority of cases. Recent studies have indicated an association between microdeletions of the azoospermia factor a (AZFa)-AZFc regions of Yq and severe oligospermia or azoospermia. Increased (CAG)n repeat lengths in the androgen receptor (AR) gene have also been reported in infertile men. Therefore, in order to assess the prevalence of these genetic defects to male infertility, 183 men with non-obstructive azoospermia (n = 70), obstructive azoospermia (n = 33), severe oligospermia (n = 80) and 59 fertile men were examined cytogenetically and at molecular level for Yq deletions, microdeletions, and AR-CAG repeat lengths along with hormonal profiles [luteinizing hormone (LH), follicle-stimulating hormone (FSH) and testosterone (T)]. We used high resolution cytogenetics to detect chromosome deletions and multiplex polymerase chain reaction (PCR) involving 27 sequence-tagged site (STS) markers on Yq to determine the rate and extent of Yq ...

May, 2019 - American Journal of Roentgenology. ABSTRACT :. OBJECTIVE. The objective of our study was to determine whether contrast-enhanced ultrasound (CEUS) perfusion measurements obtained before testicular sperm aspiration (TESA) can improve or predict sperm retrieval (SR) outcomes of TESA in patients with azoospermia.. SUBJECTS AND METHODS. Between May 2017 and January 2018, 70 patients with azoospermia (mean age, 29 years; age range, 22-41 years) underwent testes CEUS within 10 days before TESA. Major perfusion areas were visually chosen, and their ranges were recorded. The other areas were defined as minor perfusion. CEUS quantitative features were acquired for both the main perfusion area and whole testis. Testis tissue biopsies were taken for both major and minor perfusion areas by cognitive fusion, and SR outcomes were compared. Associations between testicular volume, quantitative CEUS features, and SR outcomes were analyzed.. RESULTS. Twenty-four men were found to have obstructive ...

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. The exact mechanism by which chromosomal abnormality induces infertility is not fully understood. While ...

Several authors have examined the effectiveness of percutaneous procedures for sperm retrieval in OA. Sperm retrieval rates have been quoted at approximately 100% when percutaneous epididymal and testicular retrievals are combined (38-43) (Table 1). Glina et al. reported a series of 58 men with OA treated with ICSI who underwent percutaneous epididymal sperm retrievals (with rescue TESA whenever needed). The authors reported 100% recovery of motile sperm using these combined techniques. Successful repeated PESA was performed up to three times, with recovery of motile sperm in over 80% of the cases. Forty-three percent of PESA procedures yielded sufficient spermatozoa to allow cryopreservation (42). Esteves et al. reported a SRR of 97.9% among 142 men with OA. In these series, TESA as a rescue procedure after a failed PESA was performed in 17% of the cases. One-third of the retrievals yielded a sufficient number of spermatozoa for cryopreser-vation (32). Lin et al. analyzed 100 men with ...

Information retrieval in the vector space model is based on literal matching of terms in the documents and the queries. The model is implemented by creating the term-document matrix, which is formed on the base of frequencies of terms in documents. Literal matching of terms does not necessarily retrieve all relevant documents. Synonymy (multiple words having the same meaning) and polysemy (words having multiple meaning) are two major obstacles for efficient information retrieval. Latent semantic indexing (LSI) and concept indexing (CI) are information retrieval techniques embedded in the vector space model, which address the problem of synonymy and polysemy. The method of LSI is an information retrieval technique using a low-rank singular value decomposition (SVD) of the term-document matrix. Although the LSI method has empirical success, it suffers from the lack of interpretation for the low-rank approximation and, consequently, the lack of controls for accomplishing specific tasks in information

The method of choice for sperm retrieval (SR) is based on the type of azoospermia, which can be obstructive or non-obstructive, and the attending surgeons preferences and experience. Obstructive azoospermia (OA) is associated with the inability to detect spermatozoa in the ejaculate and post-ejaculate urine after centrifugation due to the bilateral obstruction of the seminal ducts.. Hence in such cases Percutaneous Epididymal Sperm Aspiration is done. We have got successful results with PESA and we can keep the extra sample frozen for future use.. Testicular Sperm Extraction (TESE)- The extraction of the testicular tissue (Fig 12) for sperm search and isolation is done usually in PESA failed patients or proven obstructive azoospermia cases. For conventional TESE, a standard open surgical biopsy technique is used to remove the testicular tissue without the aid of optical magnification. This is a day care and minimally invasive procedure.. ...

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.

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.. ...

RESULTS. The prevalence of chromosomal anomalies and Y-microdeletions in the study population were 8.5% (25/295; 95% confidence interval, 5.6-12.3%) and 6.4% (19/295; 3.9-9.9%), respectively. The total prevalence of chromosomal anomalies and Y-microdeletions was 13.2% (39/295; 95% confidence interval, 9.6-17.6%) as five cases of non-obstructive azoospermia showed both Y structural alterations and AZFbc deletion. The corresponding figures for chromosomal anomalies in the groups with non-obstructive azoospermia, very severe oligospermia, and severe oligospermia were 21.1% (15/71; 95% confidence interval, 12.3-32.4%), 5.7% (9/158; 2.6-10.5%), and 1.5% (1/66; 0.0-8.2%). While for Ymicrodeletions they were 8.5% (6/71; 3.2-17.5%), 8.2% (13/158; 4.5-13.7%) and 0% (0/66; 0.0-4.4%), respectively. The respective overall prevalence rates for chromosomal anomalies and Y-microdeletions in these groups were: 22.5% (16/71; 13.5-34.0%), 13.9% (22/158; 8.9-20.3%), and 1.5% (1/66; 0.0-8.2 ...

Non-obstructive coronary artery disease (CAD) is particularly common in women and associated with reduced quality of life and increased cardiovascular morbidity and mortality. The project will recruit patients with angina pectoris and non-obstructive CAD by CT- coronary angiography for further imaging with contrast stress echocardiography for diagnosis of myocardial ischemia. Better characterization of patients with symptomatic non-obstructive CAD due to myocardial ischemia will be done by vascular assessment by tonometry, biochemical and genetic markers as well as quality of life questionnaire. This interdisciplinary project is expected to add new knowledge to the impact of multimodality cardiac imaging in improving diagnosis in patients with symptomatic non-obstructive CAD ...

Recently insulin resistance (IR) has been recognized as the underlying pathogenesis of chronic anovulation, hyperandrogenism, and metabolic abnormalities associated with PCOD in women. IR could be the underlying pathogenesis of chronic hypospermatogenesis leading to oligospermia and azoospermia associated with other metabolic abnormalities in men. Metformin has proven as an effective medication for not only IR but several other aspects of the PCOD including reproductive abnormalities. Therefore, insulin sensitizers, particularly metformin can be introduced as a pharmaceutical option for unexplained oligozoospermia and azoospermia associated with insulin resistance ...

The New Jersey Center for Fertility and Reproductive Medicine and Dr. Eric Daiter review current information on sperm and male factor fertility including sperm production, detection, abnormalities and possible treatments.

Male infertility is defined as any condition which adversely affects the chances of initiating a pregnancy with his female partner. Most commonly, those problems arise if unable to produce or deliver fully-functioning sperm, and problems with the production and development of sperm are the most common problems of male infertility. Sperm may be underdeveloped, abnormally shaped or unable to move properly. Otherwise, normal sperm may be produced in abnormally low numbers (oligospermia) or seemingly not at all (azoospermia).. ...

Male infertility is a bane for many a childless couple. The most common affliction that a man presents with is oligozoospermia (reduced sperm concentration ) or Azoospermia ( complete absence of sperm ).

In these cohorts, eight known TSPYL1 SNPs were identified, none of which was significantly associated with male infertility. Two potentially disease-causing variants were detected in the infertile cohort: one man with azoospermia was found to be heterozygous for the novel TSPYL1 variant c.419C,G (p.Ser140Cys), and the rare substitution c.1098C,A (p.Phe366Leu) was identified in a man with OAT syndrome in the heterozygous state. Additionally, one fertile man was found to be heterozygous for the rare variant c.487G,A (p.Val163Ile). In silico analyses predicted a nonpathogenic effect for all amino acid exchanges, although protein features might be affected by p.Ser140Cys and p.Phe366Leu, respectively.. Conclusion(s): ...

3. Due to variations in the retrieval and confirmation of isolates submitted to Sexually Transmitted Bacteria Reference Laboratory of the Health Protection Agency in 2005, the data on resistance prevalence are statistically weighted. This is done to avoid resistance estimates being under representative of sites that have a low retrieval rate and over representative of sites that have a high retrieval rate. Consequently, estimates for previous years have been recalculated in this way and so values presented here may differ slightly from to the unweighted estimates that have appeared in previous GRASP reports ...

From NCBI Gene:. This gene encodes a protein containing an RNA-binding motif in the N-terminus and four SRGY (serine, arginine, glycine, tyrosine) boxes in the C-terminus. This protein is thought to function as a splicing regulator during spermatogenesis. Multiple closely related paralogs of this gene are found in a gene cluster in the AZFb azoospermia factor region of chromosome Y. Most of these related copies are thought to be pseudogenes, though several likely encode functional proteins. [provided by RefSeq, Mar 2016]. From UniProt: ...

DAZ2 is a member of the DAZ family and is a candidate for the human Y-chromosomal azoospermia factor (AZF). This RNA-binding protein is important for…

In case of azoospermia (absence of any living sperm cells in the ejaculate) it is sometimes possible to retrieve sperm through surgical methods MESA or TESE.

TEX101 is a cell membrane protein exclusively expressed by testicular germ cells and shed into seminal plasma. We previously verified human TEX101 as a biomarker for the differential diagnosis of azoospermia, and developed a first-of-its-kind TEX101 ELISA. To demonstrate the clinical utility of TEX101, in this work we aimed at evaluating ELISA performance in a large population of fertile, subfertile, and infertile men.Mass spectrometry, size-exclusion chromatography, ultracentrifugation, and immunohistochemistry were used to characterize TEX101 protein as an analyte in seminal plasma. Using the optimized protocol for seminal plasma pretreatment, TEX101 was measured by ELISA in 805 seminal plasma samples.We demonstrated that TEX101 was present in seminal plasma mostly in a free soluble form and that its small fraction was associated with seminal microvesicles. TEX101 median values were estimated in healthy, fertile pre-vasectomy men (5436 ng/mL, N = 64) and in patients with unexplained ...
