Impact of FSHB and FSHR Genes Polymorphisms on Hormonal Profile and Sperm Retrieval Outcome in Men With Klinefelter Syndrome: A Clinical–Genetic Predictive Study

Andrology, EarlyView.
ABSTRACT Background Genetic variability within the follicle‐stimulating hormone (FSH)‐related genes might contribute to phenotypic heterogeneity in patients with Klinefelter syndrome (KS), yet its clinical impact on sperm retrieval remains unclear. Objectives To investigate the association between FSHB c.211 G > T and FSHR polymorphisms (c.2039 A > G ...

Loss‐of‐Function Variants in CCDC189 Cause Human Oligoasthenoteratozoospermia by Disrupting Sperm Flagellar and Acrosomal Architecture

Andrology, EarlyView.
ABSTRACT Background Oligoasthenoteratozoospermia (OAT), characterized by reduced sperm count, impaired motility, and abnormal morphology, is a major cause of male infertility with substantial genetic heterogeneity. However, the underlying genetic etiology remains unresolved in a large proportion of affected individuals.

Azoospermia Due to Functional and Partial Ejaculatory Duct Obstruction: A Rare Case Report and Literature Review

American Journal of Men's Health
Ejaculatory duct obstruction (EDO) is a rare but treatable cause of male infertility. This case report describes a 28-year-old male with obstructive azoospermia. The patient came to our hospital after a fertility check-up revealed azoospermia.

Neoplastic Risk in Patients With Klinefelter Syndrome

Andrology, EarlyView.
ABSTRACT Background Besides gonadal involvement (hypogonadism, male factor infertility, and testicular hypotrophy), patients with Klinefelter syndrome (KS) may suffer from several extra‐gonadic complications, including neoplastic events. Objective The aim of this review is to summarize all major clinical evidence dealing with the association between KS

Development of a nomogram for sperm retrieval at microTESE for idiopathic non‐obstructive azoospermia in a multi‐center cohort study

Andrology, Volume 14, Issue 5, Page 1202-1208, July 2026.
Abstract Background Non‐obstructive azoospermia (NOA) affects approximately 10% of infertile men and represents a major challenge in assisted reproductive technology (ART). A model that includes histological variants could be helpful in predicting sperm retrieval rate (SRR) after microdissection testicular sperm extraction (mTESE) in patients affected ...
