Many obstetricians and gynecologists and patients think that it is normal when they see the sex hormone six test results as long as the values are within the normal range, which is completely wrong. The FSH value on the third day of menstruation is usually at 5.8 and the LH value at 4.8. This is more normal. 2. The value of estrogen (E2) on the third day of menstruation should be 62-70 in order to be normal. If E2 is less than 50 pg/ml, the endometrial estrogen preparation is not enough, which is low estrogen and will have obvious clinical symptoms. 3. When estrogen is low, PRL will be high, and when you are nervous during the lab test, PRL will also be elevated. This is a physiological increase, and if it is not caused by pituitary microadenoma, there is no need to take cryptocryptine. Generally, you do not need to test progesterone (P) on the third day of menstruation, you can test it on the 22nd day of menstruation to save money and make sense.
