The Follicle Stimulating Hormone (FSH) test measures the levels of FSH in the blood. FSH is a hormone produced by the pituitary gland that plays a crucial role in the reproductive system.
In females, FSH helps regulate the menstrual cycle and stimulates the growth and development of ovarian follicles, which contain the eggs. Therefore, FSH levels are important in assessing fertility and diagnosing conditions related to the female reproductive system, such as polycystic ovary syndrome (PCOS), primary ovarian insufficiency (POI), and menopause.
In males, FSH is responsible for the production of sperm. Abnormal FSH levels in males can indicate issues with testicular function, such as testicular failure or infertility.
It is important to consider the timing of the FSH test in females, as FSH levels fluctuate throughout the menstrual cycle. Typically, FSH levels are highest just before ovulation and lowest during the mid-cycle. Therefore, the test may need to be performed on specific days of the menstrual cycle to obtain accurate results.
Additionally, FSH levels naturally increase with age in both males and females. Therefore, age-related reference ranges should be considered when interpreting the results.
