What is FSH (Follicle-Stimulating Hormone)?
FSH (Follicle-Stimulating Hormone) is a crucial hormone that regulates reproductive function in both men and women. Produced by the pituitary gland in the brain, FSH stimulates the ovaries in women and the testes in men, supporting the development of reproductive cells.
The Role of FSH in Female Reproductive Health
- Ovarian Stimulation: In women, FSH stimulates the ovaries to promote egg maturation.
- Menstrual Cycle Regulation: Plays a key role in regulating the menstrual cycle and triggering ovulation.
- Ovarian Reserve Assessment: When evaluated alongside AMH, FSH provides insight into a woman’s ovarian reserve. High FSH levels may indicate diminished ovarian reserve.
The Role of FSH in Male Reproductive Health
- Sperm Production: In men, FSH supports sperm production in the testes.
- Testosterone Levels: Indirectly influences testosterone production, contributing to healthy sperm development.
Why is an FSH Test Performed?
An FSH test is conducted to assess ovarian function and menstrual irregularities in women and to evaluate sperm production issues in men. The test may be recommended for the following conditions:
- Infertility assessment
- Irregular menstrual cycles
- Signs of early menopause
- Low sperm count or sperm production disorders
Normal FSH Levels
- In Women: Levels vary depending on the menstrual cycle. High levels may indicate a decline in ovarian reserve.
- In Men: Typically stable, but abnormalities may be linked to sperm production issues.
What Do Abnormal FSH Levels Mean?
High FSH levels in women may indicate early menopause or ovarian failure, while in men, they may be associated with testicular failure. Low FSH levels could signal pituitary gland disorders or hormonal imbalances.
