If a woman has high prolactin in early pregnancy, there is a real possibility that it may lead to embryonic arrest. Embryo development is influenced by estrogen and progesterone, and if a woman has high prolactin during pregnancy, it will inhibit the secretion of estrogen from the ovaries, resulting in the body being in a low estrogen state. In this low estrogen state, it may lead to poor embryonic development or embryonic sterilizations. If a woman is found to have high prolactin in early pregnancy, she can take drugs such as bromocriptine under the guidance of her doctor to regulate the condition, but she should strictly control the dosage of the drug and closely observe the adverse reaction of the drug. There are many reasons for embryo sterilizations, and the most common reason is chromosomal abnormality of the embryo. Therefore, if there are many times of embryonic sterilizations, it is necessary to check the chromosomes of both husband and wife.
