What is the main purpose of FSH?

The main purpose of follicle-stimulating hormone (FSH) is to regulate reproductive processes in both males and females. In females, FSH stimulates the growth and maturation of ovarian follicles, which are essential for ovulation and the menstrual cycle. In males, FSH promotes spermatogenesis by acting on the Sertoli cells in the testes. Overall, FSH plays a crucial role in fertility and reproductive health.
