The following matters should be noted for intercourse to help pregnancy: 1. In order to get pregnant quickly, intercourse should be chosen at the right time, about three days before and after female ovulation will improve the chances of conception, because under normal circumstances, sperm can survive for about three days after discharge, and eggs can survive for about two days after discharge, during which intercourse is likely to form fertilized eggs; 2. After intercourse, women should not get up immediately It is best to rest in bed for about 0.5-2 hours after intercourse to avoid the outflow of semen caused by the activity of getting up, so that more sperm can have enough time to enter the uterine cavity; 3. Choose a suitable position according to the position of the woman’s uterus, for example, women with an anterior uterus can choose a flat position, which helps the cervix to be completely immersed in semen, and women with a posterior uterus are advised to raise their hips and lie prone to help more sperm enter the uterine cavity. The prone position helps more sperm enter the uterine cavity.
