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

The six hormones in gynecological endocrine examination mainly include follicle stimulating hormone, luteinizing hormone, prolactin, estradiol, progesterone, and testosterone, which need to be comprehensively interpreted in conjunction with the menstrual cycle stage and testing purpose.

1. Follicle stimulating hormone

Follicle stimulating hormone reflects ovarian reserve function, and the normal value during follicular phase is 3-10IU/L. An increase in numerical value may indicate ovarian dysfunction, while a decrease in numerical value may be related to hypothalamic pituitary lesions. Before the examination, it is recommended to avoid vigorous exercise and emotional fluctuations. It is suggested to have a blood test taken from the abdomen on the 2nd to 4th day of menstruation.

2. Luteinizing hormone

Luteinizing hormone reaches its peak before ovulation, with a normal follicular phase value of 2-12IU/L. When the ratio of follicle stimulating hormone to follicle stimulating hormone is greater than 2, attention should be paid to polycystic ovary syndrome. When testing, the number of menstrual cycle days should be indicated, and those who use contraceptive pills need to stop taking the medication for one month before testing.

3. Prolactin

The normal value of prolactin is less than 25 μ g/L, and the increase may be related to pituitary tumors and hypothyroidism. Before drawing blood, sit still for 30 minutes to avoid nipple irritation. Mild elevation can be rechecked, while significant elevation requires further examination in conjunction with pituitary MRI.

4. Estradiol

The level of estradiol fluctuates with the menstrual cycle, and the normal value during the follicular phase is 20-150pg/ml. Low levels may indicate premature ovarian failure, while high levels should rule out ovarian tumors. Avoid using hormone drugs one week before testing, as there are significant differences in reference values between different stages of the cycle.

5. Progesterone

Progesterone reaches its peak during the luteal phase, with a normal value of 5-20ng/ml. A low value may indicate insufficient luteal function and affect conception. It is recommended to undergo testing around the 21st day of menstruation, combined with ultrasound examination to determine ovulation.

6. Testosterone

The normal value of testosterone in women is less than 0.8ng/ml, and abnormal elevation may indicate polycystic ovary syndrome or adrenal disease. Androgen drugs should be discontinued for 3 days before the examination, and adrenal function tests should be added when accompanied by symptoms such as hirsutism. Before undergoing the six hormone tests, it is important to maintain a regular sleep routine and avoid staying up late and overexertion. On the day of the examination, fasting for at least 8 hours is required, and blood collection should be done between 9-11am. If the results are abnormal, a follow-up examination should be conducted to confirm and cooperate with gynecological ultrasound, thyroid function and other auxiliary examinations. Pregnant women are advised to choose the best testing time under the guidance of a doctor, and those with irregular menstruation can use basal body temperature monitoring to help determine the stage of the cycle. All medication use must strictly follow the doctor's advice, and the dosage of hormone drugs cannot be adjusted by oneself.
