Sex hormone six is one of the common tests for patients with gynecological endocrine disorders. Through sex hormone six, it is possible to determine whether the patient has a disease in the area of endocrine disorders. Sex hormone six tests include many items, including estradiol, luteinizing hormone, progesterone, testosterone, prolactin, and follicle-stimulating hormone, a total of six items. When follicle stimulating hormone is elevated, it suggests a decrease in ovarian reserve and ovarian decline. If the ratio of luteinizing hormone to follicle stimulating hormone is greater than 2, the patient is often clinically suspected of having polycystic ovaries. If estradiol is low, it may also cause anovulation, which is related to ovarian function. If pituitary prolactin is elevated, it indicates possible hyperprolactinemia. If androgens are elevated, there may be polycystic ovary syndrome.
