A longitudinal uterus is the result of congenital developmental abnormalities. During the critical period of development of the fetal reproductive system, various harmful factors may cause developmental abnormalities in the reproductive system that can lead to a longitudinal uterus. Most women find out that they have a longitudinal uterus when they are unable to have a successful pregnancy until full term after several pregnancies or when they have a normal sex life and are unable to have a normal pregnancy for a long time, and are found to have a longitudinal uterus only during the examination when they visit the hospital. Depending on the severity of the condition, a longitudinal uterus can be classified as a complete longitudinal uterus, an incomplete longitudinal uterus or a vaginal longitudinal uterus at the same time. Depending on the severity of the condition, the impact on menstruation, sexual life and the pregnancy process may not be the same.
