Follicle stimulating hormone (FSH)

Definition

Follicle-stimulating hormone (FSH) is a gonadotropin released by the anterior pituitary gland. It plays a crucial role in regulating the reproductive processes of both males and females by stimulating the growth of ovarian follicles and spermatogenesis.

5 Must Know Facts For Your Next Test

1. FSH levels are highest just before ovulation in females, triggering the release of an egg.
2. In males, FSH works alongside luteinizing hormone (LH) to stimulate sperm production in the testes.
3. FSH secretion is regulated by gonadotropin-releasing hormone (GnRH) from the hypothalamus.
4. A decrease in FSH can result in infertility issues such as failure to ovulate or impaired sperm production.
5. FSH levels are commonly measured in fertility assessments and hormonal evaluations.
