LUTEINIZING HORMONE 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.

Constitutional mosaic trisomy 21 and azoospermia: a case report. (1/302)

Constitutional full trisomy 21 is a common disorder in which abnormal spermatogenesis has been previously described. However, constitutional mosaic trisomy 21 in an otherwise normal but infertile male has not been explored. We report a case with low level mosaic trisomy 21 in a non-syndrome but azoospermic patient. We also propose that the patient's azoospermia may be related to the constitutional mosaic trisomy 21 and thus resulting in a late onset of testicular failure.  (+info)

Mutations in the chromosome pairing gene FKBP6 are not a common cause of non-obstructive azoospermia. (2/302)

Although it is generally thought that spermatogenic failure has a genetic background, to date only a limited percentage of men with non-obstructive azoospermia (NOA) are diagnosed with a genetic defect. The only common and well-established genetic causes of NOA in humans are numerical and structural chromosomal abnormalities and Y-chromosome deletions. In addition, some infrequent mutations have been identified in the ubiquitin-specific protease 9, Y-linked (USP9Y) and the synaptonemal complex protein 3 (SYCP3) gene that cause azoospermia. FK506-binding protein 6 (Fkbp6) is a newly discovered component of the synaptonemal complex (SC), which is essential for proper chromosome pairing and meiotic division. A null mutation of the Fkbp6 gene causes azoospermia in mice as well as in rats. We tested the hypothesis whether mutations in this gene can also cause azoospermia in humans. We performed a mutation screen in 51 men with NOA through direct sequencing methods. No homozygous mutations were identified. Two heterozygous mutations (T173T and R183C) were identified, which are likely to disrupt FKBP6 protein function. However, both mutations were also found in a group of 218 normospermic controls indicating that one FKBP6 allele appears to be sufficient for normal spermatogenesis. In conclusion, our results suggest that genetic defects in FKBP6 can be excluded as a common cause of azoospermia in humans.  (+info)

Decrease of both stem cell factor and clusterin mRNA levels in testicular biopsies of azoospermic patients with constitutive or idiopathic but not acquired spermatogenic failure. (3/302)

BACKGROUND: Sertoli cells nurse germ cells during spermatogenesis, and alterations of Sertoli cell functions have been suggested in cases of spermatogenic failures. METHODS: In this work, we measured stem cell factor (SCF) and clusterin mRNA levels, by quantitative RT-PCR, in RNA extracted from testicular biopsies of 49 azoospermic patients classified according to testicular histology as having normal spermatogenesis or spermatogenic failure. RESULTS: When related to the percentage of Sertoli cells counted on a histological section of a neighbouring tissue sample, SCF and clusterin mRNA levels were significantly lower in the 'spermatogenic failure' group compared with the control group (P = 0.0297 and P = 0.0043, respectively). These levels were also significantly lower in the cases of 'constitutive' (cryptorchidism and Yq microdeletion) and 'idiopathic' spermatogenic failures when compared with the control group; conversely, they were not significantly decreased in the group with 'acquired spermatogenic failure' (orchitis, testicular traumatism, chemoradiotherapy and varicocele). CONCLUSIONS: These data further demonstrate an alteration of Sertoli cell functions in some human spermatogenic failures and suggest that a lack of Sertoli cell maturation may be involved in cases of constitutive or idiopathic spermatogenic failures.  (+info)

Association of spermatogenic failure with decreased CDC25A expression in infertile men. (4/302)

BACKGROUND: DAZ gene family is crucial for human spermatogenesis that requires the precise co-ordination of cell cycle events. CDC25A is recognized as the downstream substrate of DAZ gene family and is thought to function on the M-phase regulation of cell cycles. We investigated the expression profiles of CDC25A in the testes of infertile men and evaluated the relationship between CDC25A levels and testicular phenotype, clinical hormonal parameters and sperm retrieval results. METHODS: The protein and mRNA transcript levels of CDC25A in the testes of 40 azoospermic men were determined by immunohistochemistry and quantitative real-time-PCR. CDC25A in human spermatozoa was investigated by western blotting and immunofluorescence staining. RESULTS: The CDC25A protein was expressed mainly in spermatocyte, spermatid and spermatozoa. CDC25A transcript levels were significantly decreased (P = 0.0009) in patients with spermatogenic failure, especially in men with meiotic arrest and Sertoli cell-only syndrome. Significantly higher CDC25A transcript levels were detected in patients with successful sperm retrieval than in patients with failed sperm retrieval (P = 0.005). CONCLUSIONS: Decreased CDC25A is associated with spermatogenic failure and failed sperm retrieval in infertile men. Further studies are necessary to explore the functional roles of CDC25A in human spermatozoa.  (+info)

Beta-endorphin in serum and seminal plasma in infertile men. (5/302)

AIM: To access beta-endorphin levels in serum as well as seminal plasma in different infertile male groups. METHODS: Beta-endorphin was estimated in the serum and seminal plasma by enzyme-linked immunosorbent assay (ELISA) method in 80 infertile men equally divided into four groups: non-obstructive azoospermia (NOA), obstructive azoospermia (OA), congenital bilateral absent vas deferens (CBVAD) and asthenozoospermia. The results were compared to those of 20 normozoospermic proven fertile men. RESULTS: There was a decrease in the mean levels of beta-endorphin in the seminal plasma of all successive infertile groups (mean +/- SD: NOA 51.30 +/- 27.37, OA 51.88 +/- 9.47, CBAVD 20.36 +/- 13.39, asthenozoospermia 49.26 +/- 12.49 pg/mL, respectively) compared to the normozoospermic fertile control (87.23 +/- 29.55 pg/mL). This relation was not present in mean serum level of beta-endorphin between four infertile groups (51.09 +/- 14.71, 49.76 +/- 12.4, 33.96 +/- 7.2, 69.1 +/- 16.57 pg/mL, respectively) and the fertile control group (49.26 +/- 31.32 pg/mL). The CBVAD group showed the lowest seminal plasma mean level of beta-endorphin. Testicular contribution of seminal beta-endorphin was estimated to be approximately 40%. Seminal beta-endorphin showed significant correlation with the sperm concentration (r = 0.699, P = 0.0188) and nonsignificant correlation with its serum level (r = 0.375, P = 0.185) or with the sperm motility percentage (r = 0.470, P = 0.899). CONCLUSION: The estimation of beta-endorphin alone is not conclusive to evaluate male reproduction as there are many other opiates acting at the hypothalamic pituitary gonadal axis.  (+info)

Does PGD for aneuploidy screening change the selection of embryos derived from testicular sperm extraction in obstructive and non-obstructive azoospermic men? (6/302)

BACKGROUND: An increased incidence of aneuploid embryos has been recently described from azoospermic men. The aim of this study was to assess if embryo selection on day 5, based on morphological criteria, would be different from the selection based on PGD for aneuploidy screening (AS) in couples undergoing ICSI for male azoospermia. METHODS: Sixty-two cycles of testicular sperm extraction (TESE)-ICSI with PGD-AS were included in the analysis. Two embryologists, blinded to the PGD-AS results, retrospectively reviewed the available embryology data from day 5 embryos and selected one, two or three embryos to be transferred. These results were compared with the selected embryos based on PGD-AS. RESULTS: A total of 39 cycles from non-obstructive azoospermia (NOA) and 23 cycles from obstructive azoospermia (OA) were retrospectively analysed. If single embryo transfer (SET) had been performed, in 64.8% of the NOA cycles and 54.5% of the OA cycles, no difference in embryo choice would have occurred compared to PGD-AS and in 10.8 and 36.6% of the cycles, respectively, an aneuploid embryo would have been chosen. If double ET (DET) had been performed, in 72.9% of the NOA cycles and 86.5% of the OA cycles, no difference in embryo choice would have occurred compared to PGD-AS and in 2.7 and 4.5% of the cycles, respectively, an aneuploid embryo would have been chosen. If triple ET (TET) had been performed, the outcome would have been the same as for DET. DISCUSSION: Our results suggest that under the terms of an SET policy, the performance of PGD-AS in azoospermia would result in a higher chance of success, as the possibility of selecting a euploid embryo is enhanced.  (+info)

Role of transrectal ultrasonography in the evaluation of azoospermic men with low-volume ejaculate. (7/302)

OBJECTIVE: The purpose of this prospective study was to evaluate the incidence of distal ejaculatory system defects with transrectal ultrasonography (TRUS) among patients evaluated for azoospermia. METHODS: Forty-two patients with low-volume ejaculate and azoospermia were evaluated by physical examination, serum follicle-stimulating hormone and luteinizing hormone level determination, karyotyping, selective screening for cystic fibrosis mutations, and TRUS. RESULTS: On physical examination, in 29 patients (69%), either 1 (12 patients) or both (17 patients) of the vasa deferentia could not be palpated. In the group of 17 patients with bilateral involvement of the vasa deferentia, the ultrasonographic imaging universally showed bilateral absence or hypoplasia of the seminal vesicles with bilateral agenesis of the vasa deferentia and nonvisualization of both ejaculatory ducts. In the patients with a unilateral abnormality on physical examination, the ultrasonographic imaging showed absence of the ipsilateral seminal vesicle in 7 patients and the hypoplastic seminal vesicle in 5. In the group of 13 patients with normal physical examination findings, a variety of obstructive causes were diagnosed by TRUS examination. CONCLUSIONS: According to this study, TRUS appears to be a sensitive method for evaluating the anatomy of the distal ejaculatory system. Its safety and low costs make it a good alternative to the other invasive and expensive methods.  (+info)

Can inhibin-B predict the outcome of microsurgical epididymal sperm aspiration in patients with suspected primary obstructive azoospermia. (8/302)

AIM: To evaluate whether inhibin-B can predict the outcome of a microsurgical epidymal sperm aspiration (MESA) procedure in patients with suspected primary obstructive azoospermia (OA) and if inhibin-B can replace testicular biopsy in the diagnostic work-up of these patients. METHODS: Inhibin-B levels and testicular biopsy scores were related to the outcome of MESA in 43 patients with suspected primary OA. MESA was considered to be successful when epididymal sperm could be identified during the procedure. RESULTS: Spermatozoa were present in the epididymal aspirate in 28 out of the 43 patients (65%). Inhibin-B values were not significantly different in patients with successful or unsuccessful MESA. The modified Johnsen score, however, was significantly lower in patients with unsuccessful MESA (P = 0.003). A rete testis obstruction or epididymal malfunctioning was found in 15% of patients with suspected primary OA, reflected by unsuccessful MESA despite normal inhibin-B levels and normal testicular histology. CONCLUSION: Inhibin-B cannot replace testicular biopsy as a diagnostic tool in the work-up of patients with suspected primary OA. Testicular biopsy is useful in identifying patients with spermatogenic arrest, who might have normal inhibin-B values.  (+info)

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 ...

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 ...

TY - JOUR. T1 - Microdissection Testicular Sperm Extraction. T2 - Effect of Prior Biopsy on Success of Sperm Retrieval. AU - Ramasamy, Ranjith. AU - Schlegel, Peter N.. PY - 2007/4. Y1 - 2007/4. 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 ...
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.. ...

A new study has shown that a surgical technique called microdissection testicular sperm extraction (TESE) can effectively locate and extract viable sperm in more than one-third of adult male childhood cancer survivors who were previously considered sterile due to prior chemotherapy treatment.
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 ...
Objective: To evaluate the effect of the levels of IGF-Ⅰin the epididymis and the expression of IGF-Ⅰ in the testis of adult male rat after the administration of cyclophosphamide.Methods: Ninety-six male adult rats(8 weeks age)were divided into 6 groups.The doses given to the rats of the groups 1 to 5 were 10,20,40,80 and 100 mg/(kg·d),respectively.The remaining group was served as control.All those rats were sacrificed and IGF-I were quantitatively determined by ELISA techniques 2 and 4 weeks after the administration of the drug(by gastric fudge).Immunohistochemical SP technique was used to examine expression of IGF-I in rat testis. Results: The levels of cell factors(IGF-I)in the epididymis of the rats were gradually reduced with the increasing time and dose after administration of the drug.In the mean time the expression of IGF-I in the tissues of the testis of those rats were also gradually reduced.Conclusion: In the time of oligozoospermia/azoospermia induced by the administration of

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: ...

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 ...
