Background: Genetic factors are candidates for about 30% of male infertility with sperm production-related abnormalities. Y chromosome microdeletions are responsible for around 10% of male infertility. These microdeletions generally occur in azoospermia factor on the Yq. That is often associated with the quantitative reduction of sperm. Objective: The aim of this cross-sectional study was to determine the frequency of Yq microdeletions among idiopathic azoospermic, oligoasthenozoospermic, and oligospermic men in Shohada infertility center, Chaharmahal va Bakhtiari province...

Non-protein coding RNA, miRNAs (microRNAs), are a class of promising molecular biomarkers for forensic body fluid identification (BFI) as their small size and tissue-specific expression manners. A number of studies have shown that semen can be distinguished from forensic-related body fluids (such as menstrual blood, venous blood, vaginal fluid, saliva, etc.) using semen-specific miRNAs through microassay screening and RT-qRCR. Infertility is becoming a global health problem, affecting 10%-15% of couples worldwide, and half of the cases are the result of male factors (Lian et al...

Spermatogenesis is a multifactorial process that forms differentiated sperm cells in a complex microenvironment. This process involves the genome, epigenome, transcriptome, and proteome to ensure the stability of the spermatogonia and supporting cells. The identification of signaling pathways linked to infertility has been hampered by the inherent complexity and multifactorial aspects of spermatogenesis. Systems biology is a promising approach to unveil underlying signaling pathways and genes and identify putative biomarkers...

Zika virus infection during pregnancy can cause congenital abnormities or fetal demise. The persistence of Zika virus in the male reproductive system poses a risk of sexual transmission. Here we demonstrate that live-attenuated Zika virus vaccine candidates containing deletions in the 3' untranslated region of the Zika virus genome (ZIKV-3'UTR-LAV) prevent viral transmission during pregnancy and testis damage in mice, as well as infection of nonhuman primates. After a single-dose vaccination, pregnant mice challenged with Zika virus at embryonic day 6 and evaluated at embryonic day 13 show markedly diminished levels of viral RNA in maternal, placental, and fetal tissues...

There is awareness of likelihood of abnormal spermatozoa in obese men; however, results from previous studies are inconclusive. Advances in computer-aided sperm analysis (CASA) enable precise evaluation of sperm quality and include assessment of several parameters. We studied a retrospective cohort of 1285 men with CASA data from our infertility clinic during 2016. Obesity (BMI ≥30) was associated with lower (mean ± SE) volume (-0.28 ± 0.12, p-value = .04), sperm count (48.36 ± 16.51, p-value = ...
