Follicle-Stimulating Hormone (FSH)

Follicle-stimulating hormone (FSH) is a hormone produced by the pituitary gland in the brain. It plays a crucial role in the reproductive system of both males and females.

Functions of FSH

1. In Females:

• Stimulates the growth and maturation of ovarian follicles in the ovaries.
• Triggers the production of estrogen by the ovarian follicle cells.
• Regulates the menstrual cycle and ovulation.

2. In Males:

• Stimulates the production of sperm in the testes through the process of spermatogenesis.
• Promotes the maturation of Sertoli cells, which support the development of sperm.

Regulation of FSH

FSH production is regulated by the hypothalamus and the negative feedback loop involving the sex hormones (estrogen and testosterone) in both males and females.

Study Guide

To understand FSH better, consider the following study guide:

1. Define FSH and its role in the reproductive system.
2. Compare the functions of FSH in males and females.
3. Explain the regulation of FSH production.
4. Discuss the importance of FSH in the process of spermatogenesis and follicle development.
5. Describe the feedback mechanism that controls FSH secretion.
