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 ...

Maternal, childhood and adolescent influences on Leydig cell functional capacity and circulating INSL3 concentration in young adults: Importance of childhood infections and body mass index

Andrology, EarlyView.
Abstract Background The constitutive Leydig cell hormone insulin‐like peptide 3 (INSL3) is considered a good estimate of the adult Leydig cell functional capacity and appears to remain relatively consistent throughout adult male life, only gradually declining into old age.
