Six male endocrine examinations

In fact, men also need to undergo six endocrine tests, so that they can accurately determine whether they have some unknown medical conditions, and this is a very important pre-marital examination. Only in this way can you know whether your reproductive organs have any lesions. In addition, do not consume any food before the examination. Only when you are on an empty stomach can the relevant examination results be accurate.

1. Serum prolactin (PRL): It is secreted by lactating trophoblasts, one of the eosinophilic cells in the anterior pituitary gland. It is a simple protein hormone whose main function is to promote breast hyperplasia, milk production and milk discharge. In the non-lactation period, the normal value of blood PRL is 102-496uIU/mL.

2. Serum follicle-stimulating hormone (FSH): It is a glycoprotein hormone secreted by the alkaliphilic cells of the anterior pituitary gland. Its main function is to promote the development and maturation of ovarian follicles. The concentration of blood FSH is 3.5-12.5uIU/mL in the follicular phase, 4.7-21.5uIU/mL in the ovulatory phase, and 1.7-7.7uIU/mL in the luteal phase. Low FSH values are seen in sexual dysfunction, during estrogen and progesterone treatment, and Sheehan syndrome. High FSH values are seen in premature ovarian failure, ovarian insensitivity syndrome, primary amenorrhea, etc.

3. Serum luteinizing hormone (LH): It is also a glycogen protein hormone secreted by the alkaliphilic cells of the anterior pituitary gland. Its main function is to promote ovulation and form luteinizing hormone. The serum LH concentration is 2.4-12.6uIU/mL in the follicular phase, 14.0-95.6uIU/mL in the ovulation phase, and 1.0-11.4uIU/mL in the luteal phase. High FSH and high LH will lead to decreased ovarian reserve function or ovarian failure.

4. Testosterone measurement (T): 50% of testosterone in women is converted from peripheral androstenedione, 25% is secreted by the adrenal cortex, and only 25% comes from the ovaries. Its main function is to promote the development of the clitoris, labia and mons pubis, and it has an antagonistic effect on estrogen and has a certain effect on systemic metabolism. The plasma testosterone level of women is between 0.22-2.9

nmol/L, an increase in T value is called hypertestosteroneemia, which can cause female infertility or indicate polycystic ovary syndrome.

5. Estradiol measurement (E2) is the secretion of ovarian follicles. Its main function is to make the uterine glands grow into the proliferation stage and promote the development of female secondary sexual characteristics. The concentration of blood E2 in the follicular phase is 46.0-607

nmol/L, 315-1828 nmol/L during ovulation, 161-774 nmol/LL during luteal phase. Decreased E2 is seen in ovarian dysfunction, premature ovarian failure, and Sheehan syndrome.

6. Progesterone (P): secreted by the corpus luteum of the ovary. Its main function is to promote the transition of the endometrium from the proliferative phase to the secretory phase. The blood P concentration is 0.6-4.7 nmol/L during the follicular phase and 2.4-9.4 during the ovulation phase.

nmol/L, 5.3-86nmol/L in the luteal phase. Low blood P values in the late ovulatory phase are seen in luteal insufficiency and ovulatory uterine dysfunction bleeding.
