Fsh - GCSE Biology Definition

Reviewed by: Lára Marie McIvor

Published

FSH, or Follicle Stimulating Hormone, is a hormone produced by the pituitary gland in the brain that plays an important role in human reproduction. In females, FSH helps control the menstrual cycle and stimulates the ovaries to produce eggs. In males, it is involved in the production of sperm by stimulating the testes. FSH levels can vary based on a person's age and sex, and they are especially important during puberty, when the reproductive systems are developing. Understanding how FSH and other hormones work helps us learn more about the reproductive system and its functions.
