Posterior uterus position, which means that the longitudinal axis of the uterus remains unchanged and the whole uterus tilts backward, tends to make the cervix upturned, i.e., the uterus tilts backward, which easily affects conception. There is a difference between congenital and acquired formation of posterior uterus, but most of the posterior uterus can be successfully conceived with certain fertility guidance, and only a few more serious patients need to receive surgical treatment for posterior uterus. I. What are the risks of posterior uterus? According to clinical examination, a well-mobile uterus, regardless of its position, is not the sole cause of infertility. However, a posterior uterus that is fixed by surrounding adhesions is often caused by pelvic inflammatory disease or endometriosis, which often involves both the fallopian tubes and ovaries and is a common cause of infertility. In addition, it should be noted that some posterior uteruses have the ectocervix pointing upward, which affects the contact between the semen and the cervical opening and thus does not facilitate the smooth movement of sperm, which can also affect conception. Under normal circumstances, when the woman has intercourse in the supine position, the head of the man’s penis is usually not against the cervix, but in the gap behind the cervix deep in the vagina, which is called the posterior fornix, where the semen is also ejaculated, just as the opening of the cervix faces the posterior wall of the vagina, so that the opening of the cervix is immersed in the semen accumulated in the posterior fornix of the vagina, which facilitates the sperm to cross the cervical opening and meet the egg for conception. If the uterus is tilted too far forward or backward, the opening of the cervix will not be immersed in semen and the chance of conception will be significantly reduced. 1. Inflammatory diseases Inflammation of the fallopian tubes, uterus and ovaries of women can easily cause adhesions between the body of the uterus and the rectum at the back, resulting in a posterior position of the uterus. 2, congenital dysplasia of the uterus Such female patients often experience laxity of the uterine ligaments, which makes the bottom of the uterus tilt backward, resulting in the symptoms of retroversion of the uterus. 3, multiple abortions Women who have had multiple abortions often result in trauma to the uterus, which, combined with failure to maintain the uterus well after surgery, will eventually lead to the backward tilting of the uterus. The posterior position of the uterus makes it difficult for semen to be shot directly to the cervical opening because the opening of the cervix tends to be backward, so the probability of conception is lower than that of a normal anterior uterus (where the opening of the cervix faces forward and semen is more easily shot directly to the cervical opening). How to conceive with a posterior uterus? 1. Properly cushion the buttocks: when couples have intercourse or after sex, cushion a pillow on the woman’s buttocks, so that the woman is in a hip-high position and the cervix is immersed in semen to improve the chances of conception. 2, 30 minutes after intercourse avoid urination: after intercourse women are prohibited to urinate within 30 minutes, so as to fully let the cervix and semen contact, to improve the probability of conception. 3, the use of kneeling behind the posture of intercourse: can use the female kneeling on the back of the male position of intercourse, easy to make the upturned cervix soaked in semen. 4, prone after intercourse: after intercourse the woman lies prone, so that the semen converges to the anterior vaginal vault, increasing the probability of conception. 5.Surgery: If the posterior position is severe and not easy to conceive, you should go to a professional hospital for treatment according to medical advice. In fact, pregnancy is related to many factors, such as whether the woman’s fallopian tubes are open, whether she has endometriosis, how the ovaries are functioning, the ovulation situation, the quality of the male partner’s semen and so on. These factors together affect conception, and a posterior uterus is insignificant in the face of these problems. Therefore, women should not be too obsessed with the position of their uterus.
