Sex hormone test is also known as sex hormone test, including testosterone, estradiol, progesterone, luteinizing hormone, prolactin and follicle stimulating hormone, which is used to understand the endocrine function and diagnose related diseases. 1. Testosterone: It is an important androgen for men and is secreted by the adrenal cortex and ovaries for women. High testosterone value can be seen in adrenocortical hyperplasia and testicular tumor in men and polycystic ovary syndrome in women, and can also cause infertility if high testosterone is present. High estradiol can be seen in female precocious puberty, ovarian tumor, pituitary tumor, liver cirrhosis, systemic lupus erythematosus or pregnancy. Low estradiol is seen in primary hypogonadism, such as ovarian insufficiency, amenorrhea, renal insufficiency, etc.; 3. Progesterone: secreted by the corpus luteum and ovaries, it can promote endometrial development. If progesterone is high, it is common in normal pregnancy, gravida, gestational hypertension, ovarian tumor, multiple pregnancy, etc. Low progesterone is common in luteal insufficiency, polycystic ovary syndrome, etc. It is used to determine the presence or absence of ovulation and the luteal function of infertile women. 4. Luteinizing hormone: secreted by the pituitary gland, it can promote ovulation. A high value of luteinizing hormone can be seen in gonadotropin insufficiency, renal failure, liver cirrhosis, etc. A low value is considered as polycystic ovary syndrome; 5. Prolactin: can promote breast enlargement and milk secretion. High prolactin indicates hyperprolactinemia, which inhibits ovarian function and ovulation; 6. follicle stimulating hormone: it can promote follicle development and maturation, which can lead to low values of follicle stimulating hormone when applying hormone therapy. Therefore, women with menstrual disorders and gynecological diseases, or men with hypogonadism, semen abnormalities, pituitary diseases, etc. need to have their sex hormone 6 checked. The test for women is usually chosen on the 2nd-3rd day of menstruation, and menopausal women or men can be examined at any time by drawing blood on an empty stomach. Avoid emotional excitement or strenuous activities during the test to avoid affecting the test results.
