The FSH (Follicle Stimulating Hormone) Test measures FSH levels in the blood to assess reproductive health, fertility, and hormonal balance in both men and women.
The purpose of this test is to:
The FSH (Follicle Stimulating Hormone) test measures the level of follicle-stimulating hormone in the blood. FSH is produced by the pituitary gland and plays an important role in reproductive health. In women, it helps stimulate the growth and development of ovarian follicles and supports estrogen production. In men, FSH contributes to sperm production and testicular function.
The test is commonly used to evaluate fertility, menstrual irregularities, ovarian function, menopause, and disorders affecting reproductive hormones. In children and adolescents, FSH may also be measured when evaluating delayed or early puberty.
FSH levels naturally vary according to age, sex, menstrual-cycle phase, and reproductive status, so results should be interpreted in the appropriate clinical context. Your healthcare provider may recommend FSH testing along with other hormones such as LH, estradiol, progesterone, testosterone, or AMH, depending on the reason for testing.
1. What does the FSH test tell you?
FSH testing provides information about the function of the pituitary gland and reproductive system. In women, it can help assess ovarian function and menstrual or menopausal status. In men, it can provide information related to sperm production and testicular function.
2. When should an FSH test be done?
The appropriate timing depends on the reason for testing. For certain fertility evaluations, FSH may be measured during the early part of the menstrual cycle, while testing for menopause or other hormonal conditions may be performed at a different time. Follow the timing recommended by your healthcare provider.
3. Does a high FSH level always mean infertility or menopause?
No. FSH levels can vary based on age, menstrual-cycle phase, medications, and reproductive status. A high FSH level may be associated with reduced ovarian function or menopause in women, or certain testicular or hormonal conditions in men, but the result should always be interpreted along with symptoms and other hormone tests.
