After intercourse, follow the following methods to improve the chances of pregnancy: 1. rest in bed for at least one hour after intercourse, avoid standing immediately, as standing immediately will reduce the chances of pregnancy by 50%, because the semen will be discharged outside the vagina in large quantities. 2. if the uterus is in an abnormal position, such as a retroflexed posteriorly inclined uterus, with the cervix close to the anterior vaginal wall, then the ejaculate is ejaculated in the posterior fornix, so that the sperm will travel farther to enter the uterine cavity. It is recommended that after intercourse, it is best to rest on the bed, so that the cervix is immersed in semen and the chances of pregnancy are improved. In addition, after intercourse, in addition to resting in bed, it is necessary to keep the vulva locally clean.
