Intact spermatogenesis in an azoospermic patient with AZFa (sY84 and sY86) microdeletion and a homozygous TG12-5T variant in CFTR

Basic and Clinical Andrology
Background Azoospermia, the most severe form of male infertility, is categorized into two types: non-obstructive azoospermia (NOA) and obstructive azoospermia (OA), which exhibit significant genetic heterogeneity.

Genetic Insights into Azoospermia and Severe Oligozoospermia: Discovering Seven SNPs through GWAS and In Silico Analysis

Current Issues in Molecular Biology
Azoospermia and severe oligozoospermia represent the most extreme forms of male infertility. Despite their prevalence, the genetic foundations of these conditions are not well understood, with only a limited number of genetic factors identified so far ...

Possible Association of FAS and FASLG Polymorphisms with the Risk of Idiopathic Azoospermia in Southeast Turkey

, 2014
To investigate the association of the genetic variants of FAS/FASLG cell death pathway genes in male infertility, we genotyped the FAS -670A/G, -1377G/A, and FASLG -124A/G single-nucleotide polymorphisms (SNPs) by real-time polymerase chain reaction in ...

Predictive factors of c-TESE success in eastern algerian patients with non-obstructive azoospermia: role of histology, hormones, and testicular volume

Basic and Clinical Andrology
Background Non-obstructive azoospermia is the most severe and common form, representing 10–15% of infertile men. For these patients, testicular sperm extraction followed by intracytoplasmic sperm injection offer the only viable fertility option. However,
