There is a certain relationship between the implantation and estradiol. If the estradiol is too low, it will make the uterine lining thin, which will affect the implantation to a certain extent. After pregnancy, the estradiol value in pregnant women usually rises because the placental trophoblast cells will secrete estrogen after the embryo is implanted, so the estradiol value in the body will rise after the embryo is implanted. Low estradiol values are usually associated with low ovarian function, which can lead to ovarian failure to ovulate or absence of dominant follicles, etc., as well as a thin endometrium, which affects fertilization and embryo implantation. In addition, estradiol is also a very important hormone, the end of menstruation can quickly repair the uterine lining, stop bleeding and promote the growth of the uterine lining, which is conducive to the implantation of fertilized eggs. If the estradiol level is found to be lower than the normal range, it is recommended to consult a doctor in time, and under the doctor’s guidance, improve the relevant examinations to clarify the cause of the disease and treat the symptoms.
