Yes, trichomoniasis can be prevented.
Use a latex condom properly every time you have sexual intercourse with every partner. Always use water-based lubricants (like Maxilube®, K-Y® Jelly, or Astroglide®)1 with latex condoms. Do not use oil lubricants like petroleum jelly, baby oil or cooking oil because they can cause latex condoms to break.
Know your partner's sexual history. The more people that you or your partner have had sex with, the greater your risk of encountering someone who has this or other STDs.
Other than abstaining from sex altogether, the best way to avoid transmission of sexually transmitted diseases is to be in a long-term, mutually monogamous relationship (no other sex partners for you or your partner) with a partner who has been tested and you know is not infected.
