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 ...

Cryptorchidism: Novel genetic insights into CCDC149 mutations
Andrology, EarlyView.Abstract Background Cryptorchidism, characterized by the failure of one or both testes to descend into the scrotum, is a common congenital condition that can lead to infertility and increased risk of testicular cancer. CCDC149, a coiled‐coil domain‐containing protein, has been implicated in various developmental processes, but its role in the male ...

Mouse genome engineering uncovers 18 genes dispensable for male reproduction
Andrology, EarlyView.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.
