Follicular Stimulating Hormone


Follicle-stimulating hormone (FSH) is a gonadotropin hormone produced by the pituitary gland, crucial for the reproductive systems of both men and women.

In women, FSH performs the following functions:

  1. Ovarian Follicle Development: FSH prompts the growth of ovarian follicles in preparation for ovulation.
  2. Estradiol Production: Developing follicles secrete estradiol, an estrogen vital for the reproductive cycle.
  3. Menstrual Cycle Regulation: FSH levels fluctuate throughout the menstrual cycle, peaking just before ovulation.

In men, FSH serves the following roles:

  1. Sperm Production: FSH stimulates Sertoli cells in the testes, facilitating spermatogenesis.
  2. Testicular Health: It helps maintain the size and health of the testes.

FSH levels are utilized as a diagnostic tool to assess fertility and reproductive health. In women, abnormal FSH levels may indicate issues like ovarian failure, polycystic ovary syndrome (PCOS), or menopause. In men, abnormal levels may indicate testicular problems or issues with the hypothalamic-pituitary-gonadal axis, affecting sperm production and fertility.

Monitoring FSH levels aids in evaluating and treating infertility and understanding other reproductive health concerns.
