2. For women younger than 50 years old, if the amenorrhea is 12 months or more after stopping all exogenous hormone treatments, and the levels of luteinizing hormone (LH) and follicle stimulating hormone (FSH) are within the laboratory postmenopausal reference value range, also Can be considered post-menopausal;
