What is FSH?

By Gemma Rigby

Follicle-Stimulating Hormone (FSH): The Follicle Developer, it stimulates the growth and maturation of multiple ovarian follicles. 

FSH is present during the follicular phase. As the dominant follicle matures, it produces estrogen, which in turn suppresses FSH levels, ensuring that only one mature follicle is released during ovulation. 

Abnormal FSH levels can impact fertility by affecting the maturation of eggs and the timing of ovulation.
