Which pituitary hormone triggers sperm production in male testes and follicular development in females every month?

The correct answer is follicle-stimulating hormone (FSH). FSH is a pituitary hormone that is essential for the development and maturation of follicles in females and the production of sperm in males.

In females, FSH stimulates the growth and development of ovarian follicles, which contain immature eggs. It also stimulates the production of estrogen by the ovaries. In males, FSH stimulates the production of sperm in the testes.

Its absence or inadequacy can result in infertility or subfertility in both men and women.
