Can trichomoniasis lead to sterility?

Yes, sometimes. Trichomonas is an std caused by a single-celled parasite (it has 4 flagellae "tails" and can "swim"). In men, trichomonas infections have been reported to cause decreased sperm count and decreased sperm movement, leading to a greater risk of infertility. In women, trichomonas increases the risk of infertility by causing pelvic inflammatory disease in the fallopian tubes and connected areas.
Thanks for asking! Trichomoniasis as such causes vaginal discharge, itching and irritation and sometimes painful urination.People infected should be evaluated for syphilis, gonnorhea, chlamydia , and HIV which may contribute to infertility.
