Follicle Stimulating Hormone (FSH) is a key reproductive hormone that plays a vital role in the regulation of the menstrual cycle and fertility in both men and women. Produced by the pituitary gland, FSH stimulates the development of ovarian follicles in females and spermatogenesis in males. In women, FSH levels fluctuate throughout the menstrual cycle, peaking just before ovulation. Monitoring FSH levels is crucial in assessing ovarian reserve, as elevated FSH may indicate reduced fertility or diminished ovarian function. In men, FSH is essential for spermatogenesis, and abnormal levels can be indicative of issues affecting testicular function.
FSH levels are often measured through a blood test, especially in the evaluation of infertility or irregular menstrual cycles. Abnormal FSH levels may be associated with conditions such as polycystic ovary syndrome (PCOS), premature ovarian failure, or disorders affecting the testes in men. Understanding FSH levels is integral in fertility assessments and guiding appropriate interventions. FSH testing, along with other hormonal evaluations, helps healthcare professionals tailor treatment plans for individuals struggling with fertility issues or hormonal imbalances, contributing to more informed reproductive health management.
