Trichomoniasis affects pregnancy because trichomonas is the growth and reproduction of trichomonas in the vagina of a woman and it is easily transmitted to men. In addition, the trichomonas can swallow sperm in the vagina, so even if there is sex, the male sperm will not be able to enter the vagina. In other cases, women with trichomoniasis may have itchy and uncomfortable leucorrhea. In this case, they should be given medication under the guidance of a doctor and be reviewed after treatment.
