Chlamydia trachomatis infection can cause infertility, mainly from the following aspects: 1, after Chlamydia trachomatis infection, will cause inflammation of the fallopian tubes, the endometrium by Chlamydia trachomatis infection, endometrial inflammation or long endometrial polyps, and even cause adhesions and other problems, the path of sperm-egg union on a lot of obstacles, with these obstacles, will naturally cause difficulties in pregnancy, so that is It can cause infertility, that is, it can cause the fallopian tubes to be inaccessible or not open, or even obstruction of the fallopian tubes; 2. Because Chlamydia trachomatis is a particularly small pathogenic microorganism, it will adhere to the head of the sperm, affecting the combination of sperm and egg, and if the sperm and egg can not be combined, it is naturally impossible to get pregnant. Another great disadvantage is that once Chlamydia trachomatis infects the endometrium and is present here, even if pregnancy occurs, it can affect the health of the embryo and cause fetal malformation or miscarriage. So in so many aspects of infertility, Chlamydia trachomatis is a culprit. Therefore, once Chlamydia trachomatis infection is present, the first thing we need to do is to treat it effectively and it is safer to let her get cured before having children.
