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

Andrology, Volume 14, Issue 3, Page 897-904, March 2026.
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, Volume 14, Issue 3, Page 847-862, March 2026.
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.

Modified cytoskeletal and extracellular matrix composition in the canine testis after long‐acting gonadotropin‐releasing hormone agonist deslorelin treatment

Andrology, Volume 14, Issue 3, Page 718-735, March 2026.
Abstract Background Long‐acting gonadotropin‐releasing hormone (GnRH) agonists are commonly used for fertility control in male dogs. Their effect on testicular histomorphology has not been clarified. Objectives To elucidate the mechanisms underlying androgen withdrawal in response to long‐acting GnRH agonist deslorelin 4.7 mg treatment on testicular ...

Mouse genome engineering uncovers 18 genes dispensable for male reproduction

Andrology, Volume 14, Issue 3, Page 833-846, March 2026.
Abstract Background Male infertility is an intricate multifactorial disease involving the interplay between genetic and environmental factors. Genetic anomalies account for more than 15% of all male infertility cases; however, diagnosing them exhibits enormous challenges due to variable symptomatic presentations and limited knowledge of gene functions.
