What is the normal value of estradiol e2

Estradiol E2 is a hormone secreted by the ovarian follicles and the placenta during pregnancy. It has important reference significance for the monitoring of gynecological diseases, such as being able to effectively diagnose problems such as precocious puberty and developmental disorders. Therefore, knowing the normal value of estradiol e2 can help you compare your own situation. So, what is the normal value of estradiol e2? Let’s take a closer look at it below.

blood:

(1) Radioimmunoassay (RIA):

Male: 110-264.2pmol/L.

Female: 132-220pmol/L during follicular phase.

Ovulation period 1431-2972pmol/L.

Luteal phase 403.7-1123pmol/L.

Menopause 40.3-55.1pmol/L.

(2) Time-resolved fluorescence immunoassay (TRFIA):

Male: 0-1.6nmol/L.

Female: 0.1-0.61nmol/L during follicular phase.

0.57-1.62nmol/L during ovulation period.

Luteal phase 0.2-0.73nmol/L.

0-0.16nmol/L during menopause.

Pregnancy (July-September): 20-130nmol/L.

Urine:

0-11nmol/24h in the follicular phase.

Ovulation period 15-51nmol/24h.

Luteal phase 15-37nmol/24h.

0-15nmol/24h during menopause.

Increased: seen in childhood feminization, estrogen-producing tumors, gynecomastia, and decompensated cirrhosis. Adrenal hyperplasia. Reduce: congenital ovarian dysgenesis, menopausal syndrome, hypopituitarism, pituitary dwarfism, pregnancy toxemia, anencephaly.

The above is an introduction to the normal value of estradiol e2. I hope it will be helpful to everyone’s understanding. Although we don't use the normal value of estradiol e2 often, understanding this aspect can still help us effectively find the cause when there is a problem with our body. Only when the cause is clear can we find a better solution and avoid affecting our health.
