The position of the uterus is usually located in the central part of the pelvic cavity. There is a distinction between anterior and posterior uterine position, both of which are mainly based on the position of the uterus in the pelvis. Anterior uterine position is the most common normal uterine position for women because the normal uterus should be slightly tilted forward to facilitate the gathering of semen at the cervical opening, making it easier to conceive. The posterior position of the uterus is a slight backward tilt of the uterus, and the opening of the uterus may have an upward position change because of the posterior position of the uterus, which makes it difficult to conceive relative to the anterior position of the uterus. Generally, after sex, the hips can be properly padded to increase the amount of semen gathered in the vault of the cervical opening, which can also effectively improve the chances of conception.
