The follicle stimulating hormone (FSH) test is a blood test that measures the levels of FSH in the blood. FSH is a hormone produced by the pituitary gland that plays a key role in regulating the reproductive system. In men, FSH helps to stimulate the production of sperm, while in women, FSH helps to stimulate the growth and maturation of ovarian follicles and the production of estrogen.
The FSH test is commonly used to help diagnose or monitor conditions related to fertility and reproductive health, such as infertility, polycystic ovary syndrome (PCOS), and menopause. The test may also be used to assess hormone levels in children who are entering puberty at an early or delayed age.
The FSH test is usually done as part of a series of tests that may also include measuring levels of other hormones like luteinizing hormone (LH) and estradiol. Results from the FSH test are typically interpreted in conjunction with other tests and a physical exam to determine the underlying cause of any abnormalities in hormone levels.
It is important to consult with a healthcare provider to understand the significance of FSH test results and to discuss any necessary follow-up steps or treatment options.
