Direct action through the Sertoli cells is essential for androgen stimulation of spermatogenesis [PDF]
, 2010 Androgens act to stimulate spermatogenesis through androgen receptors (AR) on the Sertoli cells and peritubular myoid cells (PTM). Specific ablation of the AR in either cell type will cause a severe disruption of spermatogenesis.

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.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
