FSH

You should get an FSH test if you have irregular or absent periods, difficulty conceiving, or symptoms of menopause like hot flashes and night sweats. Men may need it for low sperm count or low testosterone. It is also recommended for assessing ovarian reserve before fertility treatment, and for early or delayed puberty.

No fasting is required for an FSH test. Women should usually test on days 2–5 of the menstrual cycle (often day 3) for accurate fertility assessment. Inform your doctor about oral contraceptives, hormone therapy, or fertility medicines, as these can affect results. Stop biotin supplements 48–72 hours beforehand.

No, fasting is not required for an FSH test. You can eat and drink normally before giving your sample. However, timing matters for women: the test is usually done on days 2–5 of the menstrual cycle, often day 3, unless your doctor advises otherwise. Stop biotin supplements 48–72 hours beforehand.
