Microdeletions of the azoospermia factor (AZF) regions in the Y chromosome are a well-known genetic cause of male infertility, resulting in impairment of spermatogenesis. However, the partial deletions of AZFc region related to spermatogenetic impairment are controversial. We investigated partial deletion of AZFc region and DAZ copy number in a population of Iranian infertile men and normozoospermic controls. In total, 154 infertile men (113 patients with azoospermia, 41 with oligozoospermia) and 111 normozoospermic controls were analysed using PCR...

STUDY QUESTION: Is sexual dysfunction associated with severity of semen quality impairment in men with couple infertility? SUMMARY ANSWER: In males of infertile couples the prevalence of erectile dysfunction (ED) increases as a function of semen quality impairment severity. WHAT IS KNOWN ALREADY: Infertile men are at a higher risk for sexual dysfunction, psychopathological and general health disorders. However, it has never been systematically investigated if these problems are associated with severity of semen quality impairment...

Some studies have focused on the association between male infertility and single nucleotide polymorphisms (SNPs) in the ubiquitin-specific protease 26 (USP26) gene, but the results are controversial. In this case-control study including both normozoospermic men and patients with nonobstructive azoospermia, we analyzed both the entire coding region and 5' and 3' untranslated regions of USP26 in order to identify genetic variants in this gene to investigate the role of USP26 on spermatogenesis. We reported variations in the USP26 gene sequence in 82% of azoospermic and in 50% normospermic men...

The study aimed to compare the histological features of Leydig cells and macrophages in the testicular interstitium of obstructive versus nonobstructive azoospermia. Thirty-nine azoospermic men undergoing testicular sperm extraction during intracytoplasmic sperm injection were allocated into obstructive azoospermia group (GI) and nonobstructive azoospermia group (GII) which was subdivided into Sertoli cell-only syndrome (GIIA), germ cell arrest (GIIB) and hypospermatogenesis (GIIC) subgroups. Serum LH, FSH and testosterone levels were measured...

BACKGROUND: Infertility can be the result of some common cancer treatments and can significantly impact quality of life. Semen cryopreservation allows for fertility preservation. We analyzed the semen parameters of specimens collected from pubertal males from the Children's Hospital of Philadelphia (CHOP) in order to expand current knowledge on the quality of these specimens and inform a standard clinical practice. PROCEDURE: Males who were at least Tanner stage III and newly diagnosed with cancer at CHOP were approached regarding sperm banking...

The mammalian sex-chromosomes (X and Y) have evolved from autosomes and are involved in sex determination and reproductive traits. The Y-chromosome is the smallest chromosome that consists of 2-3% of the haploid genome and may contain between 70 and 200 genes. The Y-chromosome plays major role in male fertility and is suitable to study the evolutionary relics, speciation, and male infertility and/or subfertility due to its unique features such as long non-recombining region, abundance of repetitive sequences, and holandric inheritance pattern...

In 80% of infertile men with obstructive azoospermia caused by a congenital bilateral absence of the vas deferens (CBAVD), mutations are identified in the cystic fibrosis transmembrane conductance regulator gene (CFTR). For the remaining 20%, the origin of the CBAVD is unknown. A large cohort of azoospermic men with CBAVD was retrospectively reassessed with more stringent selection criteria based on consistent clinical data, complete description of semen and reproductive excurrent ducts, extensive CFTR testing, and kidney ultrasound examination...

In the management of azoospermia, a combination of testicular sperm extraction and intracytoplasmic sperm injection (ICSI) is usually the most successful option for fatherhood. However, an outstanding question remains: How can at least a few spermatozoa be obtained from the ejaculate, thus avoiding the need for a surgical procedure? A 36-year-old man presented to Assisted Reproduction Unit with his 26-year-old wife. The ultrasound assessment revealed bilateral microlithiasis. Two spermograms revealed absolute azoospermia...

This study investigated the effect of spermatogonial stem cell encapsulated in alginate hydrogel during cryopreservation, as cells were protected against damage during cryopreservation within the hydrogel. Spermatogonial stem cells were isolated from the testes of Balb/c mice pups (6 days old), purified in laminin-coated dishes and CD90.1 microbeads, encapsulated in alginate hydrogel and then cryopreserved. After thawing, cell viability and Spermatogonial stem cell (SSC) colony diameter were evaluated. After RNA was isolated and cDNA was synthesised, the expression of stemness genes was considered using RT real-time PCR...

To evaluate the effects of follicle-stimulating hormone (FSH) treatment on cytokine gene expression in cultured Sertoli cells from men with nonobstructive azoospermia, a total of 15 azoospermic men diagnosed as obstructive azoospermia (OA) (n = 5) and nonobstructive azoospermia (NOA) (n = 10) were included in the study. NOA patients were split into two further subgroups: nFSH and hFSH serum FSH levels. Expression of cytokine gene panel (88 genes), FSHR and ABP was evaluated by real-time PCR array analysis...

INTRODUCTION: The role of zinc is critical to reproduction potential. Seminal zinc is thought to be derived almost exclusively from prostatic secretions. Sperm motility is significantly influenced by zinc. Zinc deficiency has been linked with male sterility and subfertility. AIM: To assess the influence of seminal plasma zinc on seminogram characteristics and whether endogenous testosterone affects the seminal levels of zinc. MATERIALS AND METHODS: The semen samples were obtained from 150 male partners of infertile couples who attended the Reproductive Biology Unit of the Department of Physiology, within the age 21-50 years and semen samples were analysed for the routine seminogram parameters...

BACKGROUND: Spermatogonial stem cells (SSCs) are classifiedas a unique adult stem cells that have capability to propagate, differentiate, and transmit genetic information to the next generation. Studies on human SSCs may help resolve male infertility problems, especially in azoospermia patients. Therefore, this study aims to propagate SSCs in-vitro with a presence of growth factor and detect SSC-specific protein cell surface markers. METHODS: The sample was derived from non-obstructive azoospermic (NOA) patient...

To explore that it is necessary to routinely detect chromosomes in infertile patients, we investigated peripheral blood lymphocyte karyotype in 16,294 male infertile patients in the north-east of China and analysed the incidence and type of chromosomal anomaly and polymorphism. G-banding karyotype analysis of peripheral blood lymphocytes was performed in 16,294 cases. Semen analysis was performed three times in all the men. PCR and FISH confirmed the presence of the SRY gene. The rate of chromosomal anomaly in the 16,294 male infertile patients was 4...

This cross sectional study was carried out in the Infertility Unit, Department of Obstetrics and Gynaecology, Bangabandhu Sheikh Mujib Medical University (BSMMU) from January 2011 and June 2013. Eighty one (81) consecutive azoospermic male partner of married couple, aged 20-50 years with at least two years of subfertility and no known endocrinopathy and ejaculatory dysfunction were included in this study to find out their abnormal hormonal pattern. None of them had received any form of treatment within the last 3 months prior to hormonal evaluation...
