Testosterone (T): In women, 50% of testosterone is converted from peripheral androstenedione, 25% is secreted by the adrenal cortex, and only 25% comes from the ovaries. The main function is to promote the development of the clitoris, labia and mons pubis, has an antagonistic effect on androgens, and has some influence on systemic metabolism. The plasma testosterone level in women is 0.7-2.1nmol/L with high T value, which is called hypertestosteronemia and can cause female infertility. Sex hormone six test items a progesterone (P): secreted by the corpus luteum of the ovary. The main function is to induce the endometrium to change from the proliferative phase to the secretory phase. The blood P concentration is 0-4.8mnol/L in the pre-ovulatory phase and 7.6-97.6nmol/L in the post-ovulatory phase. low blood P value in the post-ovulatory phase is seen in luteal insufficiency and ovulatory-type uterine dysfunctional bleeding. Sex hormone 6 test item 1 estradiol (E2): The function is to make the endometrial glands grow into proliferative phase and promote the development of female secondary sexual characteristics. The concentration of blood E2 is 48-52lpmol/L in the pre-ovulatory period, 370-1835pmol/L in the ovulatory period and 272-793pmol/L in the late ovulatory period. low values are seen in ovarian hypofunction, premature ovarian failure and Silhan syndrome. Sex hormone test I: Follicle stimulating hormone (FSH): A glycoprotein hormone secreted by the basophilic cells of the anterior pituitary gland, whose main function is follicular development and maturation of the ovary. The concentration of FSH is 1.5-10 U/L in the preovulatory period, 8-20 U/L in the ovulatory period, and 2-10 U/L in the late ovulatory period. low FSH values are seen during estrogen and progesterone treatment, and in Silhan syndrome, etc. high FSH values are seen in premature ovarian failure, ovarian insensitivity syndrome, and primary amenorrhea, etc. Prolactin (PR1): Secreted by the lactotropic cells of the anterior pituitary eosinophils, it is a simple protein hormone whose main function is to promote the production and discharge of milk from the enlarged mammary glands. During the non-lactation period, the normal value of blood PR1 is 0.08-0.92 nmol/L. Higher than 1.0 nmol/L is considered hyperprolactinemia. Luteinizing hormone (LH): It is also a glycogenic hormone secreted by basophilic cells in the anterior pituitary gland. The main function is to promote ovulation and the formation of the luteinizing hormone. Blood LH concentrations range from 2-15 U/L in the preovulatory phase, 20-100 U/L in the ovulatory phase, and 4-10 U/L in the post-ovulatory phase. below 5 U/L is more reliably indicative of hypogonadotropic hypogonadism, as seen in Silhan’s syndrome. A high FSH combined with a high LH is a sure sign of ovarian failure, and an LH/FSH >= 3 is a basis for the diagnosis of polycystic ovary syndrome.
