Estradiol growth pattern in early pregnancy

In the early stages of pregnancy, in order to determine whether the embryo is developing normally, pregnant women need to have blood drawn for relevant tests. The most common tests are HCG values ​​and progesterone. Of course, many women also test estradiol. In fact, in the early stages of pregnancy, estradiol will continue to increase and show a certain pattern. Next, I will introduce to you the growth rules of estradiol and other related knowledge!

1. What is the growth pattern of estradiol in early pregnancy?

1. The estradiol content is different in different periods of female life. Generally speaking, before puberty, the content is generally 0-121pmol/L; in the follicular phase, the content is approximately between 37-330pmol/L; during the ovulation phase, it becomes 367-1835pmol/L and in the luteal phase, it changes to 184-881pmol/L.

2. The estradiol content will also change at different stages of a woman's ovulation period. Generally, it is 48-521 picomoles/liter in the pre-ovulation period, 70-1835 picomoles/liter in the ovulation period, but it becomes 272-793 picomoles/liter in the post-ovulation period.

3. The amount of estradiol will vary throughout the pregnancy. It will increase slightly in normal pregnancy and drop sharply after the placenta is delivered. In the early pregnancy, it is generally 0-300ng/L, in the mid-pregnancy, it is generally 1000-8000ng/L, and in the late pregnancy, it is generally 5000-27000ng/L.

2. Is it important to test estradiol in early pregnancy?

1. Estrogen plays a very important role in maintaining pregnancy. On the one hand, it plays an important role in the preparation of the endometrium before embryo implantation and the maintenance of the luteal phase;

2. On the other hand, it promotes the synthesis of progesterone by the corpus luteum and placenta, which is beneficial to stabilize the intrauterine environment and maintain the development of pregnancy. Estradiol is secreted by the ovarian follicles and can also be produced in large quantities by the placenta in women after three months of pregnancy.

3. The main function is to promote the transformation of the endometrium into the proliferative phase and promote the development of female secondary sexual characteristics.

3. Precautions in early pregnancy

During pregnancy, it is very important to do an estradiol check, as it will directly affect the baby's health. Pregnant women should remember to pay attention to rest, eat a balanced diet, and supplement with more nutritious foods to increase resistance in order to maintain the balance of estradiol. Only in this way can you and your baby be healthy.
