Follicle-stimulating Hormone and Human Spermatogenesis [PDF]

Journal of Clinical Investigation, 1981
The role of follicle-stimulating hormone (FSH) in the control of spermatogenesis is not well established in any species, including man. We studied the effect of an experimentally-induced, selective FSH deficiency on sperm production in normal men. After a 3-mo control period, five normal men received testosterone enanthate (T) 200 mg i. m.

A case of hypogonadtropic hypogonadism due to hypophysitis discovered by secondary male infertility

IJU Case Reports, 2023
Introduction The main causes of secondary male infertility are varicocele and aging. It is rarely caused by adult‐onset hypopituitarism. The onset of hypopituitarism is often due to brain tumors, trauma, surgery, or congenital disorders.
