For the vast majority of couples, pregnancy is a natural physiological process and can be achieved as long as they are able to complete a normal sexual life. In order to improve the chance of conception, you can: 1. reduce the frequency of non-ovulatory sex, as too frequent sex can affect the number of sperm in male semen and the vitality of sperm, which will affect the chance of conception after intercourse. 2. adopt a proper sexual position, as the longer the semen stays in the vagina after intercourse, the better it is for sperm to move into the uterine cavity and improve the chance of conception. The more time a woman spends in the vagina, the more time she will be able to get pregnant after having intercourse.
