The six sex hormones are a kind of routine reproductive system examination for women, the items are folliculopoietin, luteinizing hormone, progesterone, lactogen, estradiol and testosterone, any kind of hormone problem may lead to infertility, the specific analysis is as follows: 1, folliculopoietin: it mainly promotes the maturation and development of ovarian follicles, it can reflect the reserve function of the ovaries. The higher the value of folliculopoietin, the worse the reserve function of the ovaries, the smaller the chance of successful pregnancy; 2, luteinizing hormone: it is secreted by the anterior pituitary cells and controlled by luteinizing hormone releasing hormone secreted by the hypothalamus, which changes with the changes in the levels of progesterone and estrogen. When the value of luteinizing hormone is low, it may be caused by menopausal syndrome, premature ovarian failure, pituitary or hypothalamic tumor, ovarian insufficiency, etc., which may cause infertility; 3. Progesterone: It is secreted by the corpus luteum of the ovary, and its function is to promote the endometrium to change from the proliferative phase to the secretory phase, so as to prepare for the fertilized egg to be laid and develop. If the progesterone value is low after ovulation, it may be caused by ovulatory dysfunctional uterine bleeding or luteal insufficiency, which may affect the fertilized egg’s implantation and cause difficulty in conception; 4. When the value of estradiol is low, it may be caused by premature ovarian failure, low ovarian function and Silhan’s syndrome, which will cause the pregnant egg not to be successfully laid, resulting in infertility; 6, testosterone: 50% of female testosterone is converted from peripheral androstenedione, only 25% of testosterone is secreted by ovaries, the main function is to promote the development of mons pubis, labia and clitoris, it has antagonistic effect on estrogen and can It has an antagonistic effect on estrogen and can affect systemic metabolism, and can cause infertility when testosterone values are too high. Patients should not use sex hormone drugs for at least 1 month before the sex hormone test, which is usually done on the second to fourth day of menstruation. Pay attention to a light diet before the test, avoid eating greasy, spicy and stimulating food to avoid affecting the test results.
