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.

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 ...

Normosmic idiopathic hypogonadotrophic hypogonadism due to a rare KISS1R gene mutation

Endocrinology, Diabetes & Metabolism Case Reports, 2018
Hypogonadotrophic hypogonadism is due to impaired or reduced gonadotrophin secretion from the pituitary gland. In the absence of any anatomical or functional lesions of the pituitary or hypothalamic gland, the hypogonadotrophic hypogonadism is referred ...

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

Andrology, EarlyView.
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 ...

Effect of FSH on testicular morphology and spermatogenesis in gonadotrophin-deficient hypogonadal mice lacking androgen receptors [PDF]

, 2010
Follicle stimulating hormone (FSH) and androgen act to stimulate and maintain spermatogenesis. FSH acts directly on the Sertoli cells to stimulate germ cell number and acts indirectly to increase androgen production by the Leydig cells.

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.
