Inflammation of the female reproductive tract, including vaginitis, cervicitis, endometritis, salpingitis and periovarianitis, can affect conception and is one of the main causes of female infertility. When there is inflammation in the vagina, a large number of pus cells can swallow sperm, reduce sperm vitality and shorten sperm life. Trichomonas vaginalis can reduce the number and quality of sperm in addition to swallowing sperm directly. In addition, the wife has trichomonas vaginitis, transmitted to the husband through sex, can cause male urethra, prostate or epididymitis, directly affecting the production and health of spermatozoa, which reduces the chances of conception, and even causes infertility. Inflammation of the uterine cervix, the discharge of purulent fluid with bacteria can kill sperms, even if the sperms survive, it is not easy to pass through the cervix into the uterine cavity, thus reducing the rate of conception. Endometritis changes the normal environment of the uterus, and even if the sperm survives, even if it combines with the egg to form a fertilized egg, it can’t “settle” in the uterus. Inflammation of the fallopian tubes can cause obstruction of the uterine cavity, so that the transport of eggs and sperm entry is impeded, sperm can not meet with the egg combination, which is an important cause of female infertility, accounting for about 1/3 of the causes of female infertility. female reproductive tract inflammation can affect the conception of the, but if you can find out in time, active treatment, can increase the chances of conception and get pregnant.
