Low testosterone in primary infertile men is associated with a history of maternal obesity during pregnancy: Findings from a cross‐sectional study

Andrology, EarlyView.
Abstract Background Maternal obesity increases offspring obesity risk, but limited data exist on its association with reproductive hormones in infertile males. Objectives To investigate the impact of maternal obesity during pregnancy on total testosterone levels in primary infertile men.

Vitamin D levels and biomarkers of male fecundity: A study from the Danish National Birth Cohort

Andrology, EarlyView.
Abstract Background Vitamin D is metabolised throughout the male reproductive system, suggesting a direct regulatory role of vitamin D in male reproduction. Objectives To investigate the association between plasma vitamin D levels at sperm ejaculation and during spermatogenesis and biomarkers of male fecundity in young men.

The role of iron in normal and impaired testicular function

Andrology, EarlyView.
Abstract Iron plays a critical role in testicular physiology, impacting spermatogenesis, testosterone production, and overall testicular function. Iron homeostasis is maintained through systemic and cellular regulatory mechanisms, including hepcidin‐mediated systemic iron control and the iron‐responsive element/iron regulatory protein (IRE/IRP) system ...

Comparative efficacy of varicocelectomy and intrauterine insemination in varicocoele patients with mild semen abnormalities: An observational study

Andrology, EarlyView.
Abstract Background Varicocoele is a common cause of male infertility, affecting spermatogenesis through increased testicular temperature, venous stasis, and oxidative stress. Microsurgical subinguinal varicocelectomy improves semen quality, whereas intrauterine insemination is widely used for mild male factor infertility.
