The thin endometrium is difficult to conceive normally, and it can lead to infertility in serious cases. The specific reasons are as follows: First, it affects embryonic development: the thin endometrium has poor blood supply, which may also affect the blood supply after the implantation of the fertilized egg, thus affecting embryonic development, which may lead to abortion, embryo termination, slow development, etc. Second, it causes placenta previa: thin endometrium, poor blood supply, and the placenta may maintain fetal blood oxygen supply through compensatory increase of area. Third, it causes placenta implantation: the placenta is attached to the inner wall of the uterus and develops. The endometrium is thin, and placental tissue may invade the myometrium. Fourth, the endometrium is the "hotbed" for the development of the fertilized egg after implantation. The thin endometrium may lead to the failure of the fertilized egg to be implanted, thus causing infertility.
