The effect of a longitudinal uterus on pregnancy varies from person to person. Usually, it is not easy to get pregnant with a longitudinal uterus and after pregnancy, it is prone to miscarriage, premature birth and abnormal fetal position. However, some women do not know they have a longitudinal uterus until after normal delivery or after a cesarean section, and this type of longitudinal uterus does not require treatment. In most cases, it may affect the fertilization of the egg and the development and growth of the embryo in the future. Therefore, patients with a longitudinal uterus may be monitored for early embryonic development by progesterone and blood HCG after pregnancy. In the middle and later stages of pregnancy, care should be taken to avoid premature rupture of membranes, miscarriage or preterm delivery. Patients with longitudinal uterus who have a history of adverse pregnancy and delivery should seek early medical attention for hysteroscopic surgery to correct the malformed uterus in time to provide good reproductive conditions for normal delivery and normal fetus in the future.
