To evaluate the diagnostic efficacy of needle aspiration biopsy of seminiferous tubules (NABST) and to represent the redistributed diagnostic results corresponding to testicular volumes and follicle-stimulating hormone (FSH) levels. In this retrospective study, we investigated 65 infertile men with either azoospermia or oligoasthenoteratozoospermia. Following NABST, specimens were stained with hematoxylin and eosin and classified into five histological types. With pre-procedure FSH levels and testicular volumes, we evaluated the probabilities of detecting sperms within biopsy specimens...

The purpose of the present multicenter study was to investigate whether an artificial insemination with donor sperm (AID) procedure after intra-couple intracytoplasmic sperm injection (ICSI) failure offers a significant chance of pregnancy and to identify prognostic factors for pregnancy after an AID procedure. An eleven-year retrospective multicenter study was conducted among 13 Centre d'Etude et de Conservation des Oeufs et du Sperme (CECOS) centers. A total of 319 couples having undergone an AID procedure after intra-conjugal ICSI failure were included in this study; a total of 1,159 AID and 1,011 intra-conjugal ICSI cycles were performed...

Duplications of Yq arm (and AZF) seems to be tolerated by fertile males, while mutations, deletions, duplications or haploinsufficiency of SHOX can originate a wide range of phenotypes, including short stature and skeletal abnormalities. We report a case of non-obstructive azoospermia in a young man with short stature, skeletal anomalies, normal intelligence and hormonal parameters. This male showed a very singular Y-chromosome aberration, consisting of a duplication of Yq and proximal regions of Yp, with a deletion of almost all PAR1 in Yptel, including SHOX...

PURPOSE: Recently, genome-wide association studies of a Hutterite population in the USA revealed that five single nucleotide polymorphisms (SNPs) with a significant association with sperm quality and/or function in ethnically diverse men from Chicago were significantly correlated with family size. Of these, three SNPs (rs7867029, rs7174015, and rs12870438) were found to be significantly associated with the risk of azoospermia and/or oligozoospermia in a Japanese population. In this study, we investigated whether the rs10966811 (located in an intergenic region between the TUSC1 and IZUMO3 genes) and rs10129954 (located in the DPF3 gene) SNPs, previously related to family size, are associated with male infertility...

Present study deals with results of fine needle aspiration of both the testes in a patient with azoospermia. Surprisingly, aspiration of right testis revealed large number of microfilariae in the smears. Conversely, left testicular aspirate showed few spermatogonia. However, microfilariae were not detected in venous blood smears. Findings of this study suggested possible role of Wuchereriabancrofti in causation of azoospermia.

BACKGROUND: The prevalence of obesity is increasing worldwide, with a corresponding increase in overweight and obese patients referred with infertility. This systematic review aimed to determine whether non-surgical weight reduction strategies result in an improvement in reproductive parameters affected by obesity, e.g. delayed time to pregnancy, oligozoospermia and azoospermia. No prior reviews have examined this within the general fertility population, or in both sexes. OBJECTIVE AND RATIONALE: Our objective was to answer the question: 'In overweight and obese women, men and couples seeking fertility treatment, what non-surgical weight-loss interventions have been used, and how effective are they at weight loss and improving reproductive outcomes?' SEARCH METHODS: An electronic search of MEDLINE, EMBASE and the Cochrane Library was performed for studies between January 1966 and March 2016...

OBJECTIVE: The FAS/FASL interaction plays a central role in up-regulation of apoptosis in testis. Studies indicated that the FAS-670A/G and FASL-844C/T polymorphisms are associated with the risk of idiopathic azoospermia in different ethnic groups. Therefore, the current study aims to investigate the association between FAS-670A/G and FASL-844C/T polymorphisms with male idiopathic infertility in Western Iran. STUDY DESIGN: The analysis of FAS-670A/G and FASL-844C/T polymorphisms were carried out using the PCR-RFLP approach, on 102 infertile men and 110 normal fertile men as control group...

A recent study found that three recurrent deletions of X chromosome linked copy number variations (CNVs), CNV64, CNV67 and CNV69 were associated with idiopathic male infertility in Spanish and Italian populations, especially CNV67 resembling the azoospermia factor deletions. That merits further investigations among different populations. This study was conducted to examine the prevalence of the three CNVs deletions and their associations with idiopathic male infertility in Chinese Han population. The present study included a large population of 1550 Chinese Han subjects recruited between 2014 and 2016...

Most male patients with non-obstructive azoospermia (NOA) have no therapeutic options outside of assisted reproductive techniques to conceive a biological child. If mature sperm cannot be obtained from the testes, these patients must rely on options of donor sperm or adoption. Several techniques are in the experimental stage to provide this patient population alternatives for conceiving. Areas covered: This review discusses three of the experimental techniques for restoring fertility in men with NOA: spermatogonial stem cell transplantation, the use of adult and embryonic stem cells to develop mature gametes and gene therapy...

REVIEW
Robert M Coward, Jesse N Mills
A variety of surgical options exists for sperm retrieval in the setting of obstructive azoospermia (OA). With appropriate preparation, the majority of these techniques can safely be performed in the office with local anesthesia and with or without monitored anesthesia care (MAC). The available techniques include percutaneous options such as percutaneous epididymal sperm aspiration (PESA) and testicular sperm aspiration (TESA), as well as open techniques that include testicular sperm extraction (TESE) and microsurgical epididymal sperm aspiration (MESA)...
