Follicle-maturation hormone, also known as FSH, has a normal value of 5-40 ml U/ml. The physiological function of FSH is to promote the maturation and development of follicles in the ovaries, hence the name follicle-maturation hormone, and the value in the blood is mostly variable, varying at different stages of egg maturation and ovulation. During ovulation, the value is higher, usually around 20 mlU/ml, and during the first stage of ovulation, the value is mostly between 1.5-10 mlU/ml, and after ovulation, it gradually decreases to between 2-10 mlU/ml. Therefore, it is better for women to have the hormone 6 test about one week after menstruation. In addition, the measurement value may fluctuate during contraceptive pills, estrogen medication, pregnancy, menopause, etc. Therefore, when doing the test, ask for medical history and analyze the normal value differently.
