What do you think of the six hormones in gynecological endocrine examination?

The six hormone levels in gynecological endocrine examination should be comprehensively evaluated based on the detection values and menstrual cycle, mainly assessing the levels of follicle stimulating hormone, luteinizing hormone, prolactin, estradiol, progesterone, and testosterone. The six hormone tests are commonly used to diagnose endocrine disorders such as polycystic ovary syndrome, premature ovarian failure, and hyperprolactinemia.

1. Follicle Stimulating Hormone

Follicle stimulating hormone is secreted by the pituitary gland and promotes follicular development. The normal value during follicular phase is 3-10IU/L, and during ovulation phase it can reach 10-20IU/L. A high value may indicate ovarian dysfunction, while a low value may be related to hypothalamic or pituitary lesions. Avoid vigorous exercise before examination, and fasting blood collection is more accurate.

2. Luteinizing hormone

Luteinizing hormone and follicle stimulating hormone synergistically regulate the menstrual cycle. The normal value during follicular phase is 2-10IU/L, and the peak value during ovulation can reach 20-60IU/L. A ratio of luteinizing hormone to follicle stimulating hormone exceeding 2 may indicate polycystic ovary syndrome. It is recommended to choose the 2nd to 4th day of menstruation for the examination.

3. Prolactin

The normal value of prolactin is 5-25ng/mL, and excessive levels may cause amenorrhea or galactorrhea. Before the examination, it is necessary to maintain emotional stability and avoid stimulating the nipples. If the value slightly increases, it can be rechecked. If it significantly increases, pituitary tumors should be ruled out. Factors such as stress and medication may interfere with the results.

4. Estradiol

Estradiol reflects the development of follicles, and the normal value during the follicular phase is 20-150pg/mL. A low value may indicate abnormal ovarian function, while a high value should alert the ovaries to excessive stimulation. Avoid taking hormone drugs one week before the examination, as the reference values may vary greatly between different stages of the cycle.

5. Progesterone

Progesterone reaches its peak during the luteal phase, with a normal value of 5-20ng/mL. Insufficient values may indicate luteal insufficiency and affect embryo implantation. It is recommended to undergo testing around the 21st day of menstruation, which should be combined with ultrasound examination for comprehensive evaluation. Avoid vigorous exercise before the examination.

6. Testosterone

The normal value of female testosterone is 0.1-0.75ng/mL. Excessive values may be accompanied by symptoms such as hirsutism and acne, commonly seen in polycystic ovary syndrome. Fasting for 8 hours is required before the examination to avoid the use of androgen preparations. Mild elevation can be intervened through lifestyle measures first.

For the six hormone tests, it is necessary to choose a specific period of menstruation, avoid sexual activity and vigorous exercise for the three days before the test, and maintain a regular schedule. If the result is abnormal, it should be rechecked and confirmed, and further examinations such as ultrasound should be conducted in conjunction. In daily life, it is necessary to maintain emotional stability, maintain a balanced diet, control weight, and avoid excessive dieting or obesity that can disrupt endocrine function. When symptoms such as menstrual disorders and infertility are discovered, timely medical attention should be sought, and a professional doctor should make a comprehensive judgment based on clinical manifestations and other examinations.
