What is the normal value of estradiol in the follicular phase?

When it comes to estradiol, I believe that many people in life don’t know what it is. In fact, it is a natural estrogen secreted by the follicles after the ovaries mature. Whether a woman’s body is normal or not also depends on this estradiol. So let’s take a look at the normal value of estradiol in the follicular phase.

If a woman's estradiol level is too low or too high, it can be very harmful to her health. In addition to causing endometrial shedding, it can even lead to infertility, so abnormal estradiol levels require timely medical attention and treatment. So what is the normal level of estradiol?

Normal estradiol levels

For women before puberty, 0-121pmol/L; for women during the follicular phase, 37-330pmol/L; for women during the ovulatory phase, 367-1835pmol/L; for women during the luteal phase, 184-881pmol/L; for men before puberty, 0-148pmol/L; for adults, 0-942pmol/L.

Increased: seen in feminization of children, estrogen-producing tumors, gynecomastia, decompensated cirrhosis, adrenal hyperplasia,

Decreased: seen in Turner syndrome, primary and secondary hypofunction.

What does estradiol do?

1. As one of the sex hormones, estradiol can cause the thinning of the endometrium and less menstrual flow if its value is too low. It can also affect the development of follicles, thus affecting conception. Estradiol is an essential ovarian hormone that stimulates the glands in the cervix to secrete a special mucus ("mucus with fertility characteristics") that is very important for sperm to pass through the cervix and reach the egg.

2. Estradiol also stimulates the growth of the endometrium. Progesterone prepares the endometrium, which has been stimulated to grow by estradiol, for the fertilized egg to implant. When there is no pregnancy, the production of estradiol and progesterone begins to decline about 7 days after ovulation, causing the endometrium to fall off 11-16 days after ovulation, resulting in menstrual bleeding.

3. If you have not given birth to a child yet but want to have a baby, you should regulate your body if your estradiol level is low. Go to a regular professional hospital for examination and diagnosis, and let the doctor develop a regulation plan based on your actual situation.

Estradiol accounts for a very important proportion in women's bodies, so once you find that your body is abnormal, or if the normal value of your estradiol is found out during a check-up, you must receive symptomatic treatment, because estradiol also has many functions for women. It can help sperm and eggs combine with each other. If estradiol is low, it may also affect fertility, so you must be cautious.
