The level of estradiol in early pregnancy is not directly related to gender. Estradiol is a type of estrogen that is normally produced gradually in a woman’s body after pregnancy and may remain at a relatively stable level in the later stages of pregnancy. Everyone’s body is different, so the level of estradiol production during early pregnancy varies. The sex of the fetus is determined by the chromosomes and is not directly related to the hormone secretion in the body. To determine the sex of the fetus, an ultrasound is usually required and the doctor will identify the sex of the fetus based on the results of the examination. In the absence of medical indications, sex determination is not allowed. Whether it is a boy or a girl, normal development and health is the most important thing. If there are any abnormalities in the development of the fetus, you should seek medical attention.
