Mild malformation of the uterus is usually able to develop normally, but if the uterine cavity is severely malformed so that the cavity is narrowed, the growth space of the fetus will be restricted, affecting the normal development of the fetus. Uterine malformations are due to congenital structural abnormalities or structural changes in the uterus caused by acquired trauma. Mild malformations of the uterus do not affect the normal growth and development of the fetus. However, severe malformations may lead to restriction of the growth space of the fetus, resulting in poor development of the fetus, and in severe cases, miscarriage and preterm delivery, which can be minimized by preconception corrective surgery. If uterine deformities are found to exist, it is recommended to seek medical attention in time to have the uterus corrected and operated on in advance to promote normal fertility. If a woman with uterine abnormalities is already pregnant, she needs to have adequate pregnancy tests to monitor the condition of the fetus.
