OBJECTIVE: To compare the expression levels of ZMYND15 and its target haploid genes (TNP1, PRM1and SPEM1) in testicular samples of non-obstructive azoospermia (NOA) vs. obstructive azoospermia (OA). The level of these transcripts were also compared in azoospermic samples with positive and negative sperm retrieval (SR). METHODS: This study included 63 testis biopsy samples from 16 OA and 47 NOA individuals. Expression levels of these target genes were determined by real-time reverse transcription-polymerase chain reaction using ΔΔCt method...

We performed immunofluorescent analysis of DNA hydroxymethylation and methylation in human testicular spermatogenic cells from azoospermic patients and ejaculated spermatozoa from sperm donors and patients from infertile couples. In contrast to methylation which was present throughout spermatogenesis, hydroxymethylation was either high or almost undetectable in both spermatogenic cells and ejaculated spermatozoa. On testicular cytogenetic preparations, 5-hydroxymethylcytosine was undetectable in mitotic and meiotic chromosomes, and was present exclusively in interphase spermatogonia Ad and in a minor spermatid population...

Severe ovarian hyperstimulation syndrome (OHSS) is a potentially life-threatening complication of assisted reproductive technology. Herein, we report the case of an infertile couple, with the husband being azoospermic, who underwent in-vitro fertilisation and intracytoplasmic sperm injection at our institute. The woman presented with late OHSS 7 days after embryo transfer. Inpatient management was performed with intensive surveillance. Oral cabergoline was started prophylactically but was replaced by the vaginal route due to intolerance...

In males with nonobstructive azoospermia, one of the main histopathologic patterns of the testis is Sertoli cell-only syndrome (SCOS), in which no germ cells are present and only Sertoli cells are contained in the seminiferous tubules. There is not any formal treatment for this pathological condition. However, several studies reported the possibility to perform testicular sperm extraction in patients with SCOS, although, according to some authors, sperm retrieval is possible only in the presence of focal spermatogenesis...

Identification of molecular markers which can predict the outcome of sperm retrieval non-invasively in patients with non-obstructive azoospermia (NOA) are valuable in clinical andrology. Jumonji domain-containing 1a (JMJD1A) is a significant epigenetic regulator during spermatogenesis, which plays an important role in the differentiation of post-meiotic germ cells into mature spermatozoa. We therefore aimed to examine the potential association between JMJD1A expression and the outcome of sperm retrieval in patients with NOA...

Busulfan is an alkane sulfonate currently used as an anticancer drug and to prepare azoospermic animal models, because it selectively destroys differentiated spermatogonia in the testes. However, few studies have focused on the exact effects of busulfan treatment on the epididymis currently. This study assessed the effect of busulfan on epididymal morphology and the blood-epididymis barrier in mice. We treated mice with a single injection of busulfan and detected the effect at different time points. We showed that busulfan was toxic to the morphological structure and function of the epididymis...

Azoospermia, the absence of any sperm cells from the ejaculated semen, poses a real challenge to the fertility urologist. While there are options to create happy families for azoospermic couples, such as the use of donor sperm and adoption, most couples still want to have genetically related offspring. Advances in urology, gynecology, and fertility laboratory technologies allow surgical sperm retrieval in azoospermic men and achievement of live births for many, but not all azoospermic couples. At present, there are extensive research efforts in several directions to create new fertility options by creating "artificial sperm cells...

Infertility has become a major health issue in the world. It affects the social life of couples and of all infertility cases; approximately 40-50% is due to "male factor" infertility. Male infertility could be due to genetic factors, environment or due to gonadotoxic treatment. Developments in reproductive biotechnology have made it possible to rescue fertility and uphold biological fatherhood. In vitro production of haploid male germ cell is a powerful tool, not only for the treatment of infertility including oligozoospermic or azoospermic patient, but also for the fertility preservation in pre-pubertal boys whose gonadal function is threatened by gonadotoxic therapies...

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...

REVIEW
Taylor P Kohn, Jaden R Kohn, Alexander W Pastuszak
Clinical varicoceles have been associated with impaired semen parameters and male-factor infertility. Varicocele repair can improve live birth rates for men with clinical varicocele. Varicocelectomy is often combined with assisted reproductive techniques (ART) such as intrauterine insemination (IUI), in vitro fertilization (IVF), or intracytoplasmic sperm injection (ICSI). Here we review the literature examining varicocelectomy before ART to evaluate whether improved pregnancy outcomes are realized. Although insufficient evidence exists to determine if correcting a varicocele improves IUI outcomes, a clinical benefit is observed when correcting a clinical varicocele in oligospermic and nonobstructed azoospermic men before IVF/ICSI...
