At the end of the intercourse, the penis expels the semen, while still being inside the vagina. In certain cases, the semen might leak out of the vagina simply because of gravity, in which case changing the position of the female pelvis in order to keep the semen might be helpful. Sometimes, the anatomical position of the service is such that the semen cannot reach its vaginal end to enter and to proceed towards the uterine cavity. Keeping the pelvis elevated (for example, by putting a pillow under the pelvis), while lying on her back might help the woman to keep the semen inside and make the semen reach the cervix.

There is also one more possible cause for the semen not entering the cervix, which is the presence of antibodies that fight the spermatozoids.


You might want to have your wife visit her gynecologist to check for anti-spermatozoal antibodies and for additional advice on how to keep the semen inside the vagina and to make it reach the uterus.
