If you want to get pregnant, there is no point and no scientific basis to perform inversion after sex. Sperm do not enter the uterine cavity faster because of the inverted position, it depends on the condition of the woman’s cervix and the environment in the uterine cavity. In addition, it depends on whether the woman is ovulating or not. During the ovulation period, as long as 1-2 normal sperm enter the uterine cavity, pregnancy can be achieved without inversion, which can be done in normal position. And inversion is a more dangerous exercise, so do not invert after sex to avoid accidental injury. Normal sex is fine, and you can also monitor ovulation to increase the probability of pregnancy. In addition, you can take some folic acid, which is also helpful to improve the probability of pregnancy.
