What does FSH stimulate the product of in the testes?

Follicle-stimulating hormone (FSH) stimulates the Sertoli cells in the testes to promote the production of sperm cells through a process called spermatogenesis. Additionally, FSH is involved in the secretion of inhibin, which helps regulate sperm production by providing feedback to the pituitary gland. Overall, FSH plays a crucial role in male fertility and reproductive health.
