If you are planning to get pregnant, it is recommended not to cleanse immediately after intercourse, because standing immediately after intercourse will reduce the chances of pregnancy by 50%, because a large amount of sperm will flow out of the vagina, so the amount of sperm entering the uterine cavity will be reduced, so the chances of pregnancy will be reduced. It is possible to cleanse the sperm on the next day. After intercourse, it is recommended that if the uterus is posteriorly flexed and posteriorly inclined, it is recommended to rest on the bed in a prone position for one hour so that the cervix will be immersed in the semen, which will increase the chances of pregnancy; if the uterus is anteriorly flexed and anteriorly inclined, after intercourse, the buttocks can be padded and the cervix will also be immersed in the semen, which will increase the chances of pregnancy.
