If the woman is in the superior position during sex, such as when the uterus is in a retroverted position, the sperm is ejaculated directly into the anterior fornix. Clinically, it may also be easy to get pregnant, but it is only relative and not absolute. It is recommended that after intercourse: 1, do not stand up immediately: because if you stand up immediately the chances of pregnancy will drop 50%, because a large number of sperm will flow out of the vagina. 2, rest position: if the uterus is backward bend and backward tilt, it is recommended that the woman is best to lie down on the bed to rest for an hour, so that the cervix will be immersed in the semen in the chances of pregnancy will be greatly increased. If the uterus is in anterior flexion and anterior tilt position, the cervix will be close to the back wall of the vagina. It is recommended that you rest your buttocks for an hour after intercourse to help you get pregnant.
