What is the normal value of E2 estradiol?

E2 estradiol is mainly produced by the ovarian follicles and the placenta during pregnancy. When precocious puberty and developmental disorders occur, the examination of e2 estradiol is of great value. Therefore, knowing the normal value of e2 estradiol can effectively judge the problems in the body, and it is very necessary for us to understand it in detail. So, what is the normal value of e2 estradiol? 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.

The above is an introduction to the normal value of e2 estradiol. I hope it will be helpful to everyone’s understanding. The normal value of e2 estradiol reflects the normal condition of the body. If it is too low or too high, we must actively look for the cause and take effective measures to treat it. Otherwise, many women will become infertile, and the consequences can be imagined.
