What are the normal ranges for the six sex hormones in children?

The LH level ranges from 2 to 15 mIU/ml in the pre-ovulatory phase, 30 to 100 mIU/ml during ovulation, and 4 to 10 mIU/ml in the post-ovulatory phase. The normal value during the non-ovulatory phase is generally between 5 and 25 mIU/ml. A level below 5 mIU/ml suggests inadequate gonadotropin function, which is seen in Sheehan's syndrome.

The FSH level ranges from 1.5 to 10 mIU/ml in the pre-ovulatory phase, 8 to 20 mIU/ml during ovulation, and 2 to 10 mIU/ml in the post-ovulatory phase. The normal range is generally considered to be 5 to 40 mIU/ml.

The normal blood PRL level is 0.08 to 0.92 nmol/L. A level above 1.0 nmol/L is considered hyperprolactinemia.

The estradiol level ranges from 48 to 521 pmol/L in the pre-ovulatory phase, 70 to 1835 pmol/L during ovulation, and 272 to 793 pmol/L in the post-ovulatory phase. The progesterone level is 0 to 4.8 nmol/L before ovulation and 7.6 to 97.6 nmol/L in the post-ovulatory phase. The normal concentration of testosterone is 0.7 to 3.1 nmol/L.

The testing methods vary depending on the specific items being tested. The content can be comprehensively examined or checked individually.

1. Testing for estrogen, progesterone, and follicle-stimulating hormone involves venous blood sampling and separation of serum, requiring 2 milliliters for each test. 2. Testing for testosterone involves drawing 2 milliliters of venous serum. The commonly used method is radioimmunoassay, which allows for measurement after serum separation. 3. Prolactin should be tested on an empty stomach, with serum collected around 9 am. 4. Testing for luteinizing hormone also involves radioimmunoassay, but since luteinizing hormone is secreted in a pulsatile manner, it is recommended to collect samples 3-4 times within 1 hour and mix them together for more accurate measurement.
