Trichomonas is not necessarily caused by men, and both men and women can be infected with trichomonas. Since men are usually asymptomatic after trichomonas infection, they can easily become the source of infection and spread to their sexual partners through sexual contact. You can learn about trichomonas through the following aspects: 1, trichomonas parasite site: trichomonas can be parasitic in the glands of the female perineum or vaginal folds, but also in the male foreskin folds, urethra or prostate. 2, trichomonas environment: public baths, bath tubs, bath towels, swimming pools, bidets, contaminated clothing, contaminated instruments or dressings, etc. 3, trichomoniasis transmission: trichomonas is mainly transmitted through sexual contact, male and female can become the first source of infection. It can also be indirectly transmitted by public baths, swimming pools and other contacts. Therefore, it is important to pay attention to sexual hygiene in daily life, avoid frequent unprotected sex, avoid sexual intercourse until the disease is cured, pay attention to high-temperature disinfection of underwear and towels in close contact, and take protective measures in public places such as baths and swimming pools. Trichomonas vaginalis can swallow sperm and can cause infertility if not treated thoroughly or for a long time. Therefore, when trichomoniasis is diagnosed, both the patient and her sexual partner need to be treated actively to prevent infertility and reinfection.
