The posterior position of the uterus does not have a significant effect on pregnancy. If you are worried, you can put a pillow under the woman’s buttocks while having sex and then remove the pillow after half an hour after sex, which will facilitate the entry of sperm into the cervical opening. The posterior uterus does not need to be very worried about pregnancy. If there is infertility, a full medical examination can be done, which is usually not related to the posterior uterus. The causes of non-pregnancy due to a posterior uterus can be changed by adopting these approaches during sexual intercourse.
