If you are planning to get pregnant, it is recommended that you lie down in bed for at least one hour after intercourse before standing up or going straight to bed. This is because if you stand up or go to the toilet to wash your vulva or urinate immediately after intercourse, more semen will flow out of your body, which will reduce the chance of pregnancy by 50%. In addition, if the uterus is in retroflexion and posterior tilt, the cervix will be close to the front wall of the vagina. It is recommended to take a prone position after intercourse and rest on the bed for 1-2 hours, so that the cervix will be immersed in semen and the chance of pregnancy will increase. If the uterus is in an anteverted position and the cervix is pressed against the posterior vaginal wall, it is advisable to raise the hips after intercourse, which will also increase the chance of pregnancy.
