Is truvada (emtricitabine and tenofovir) a good choice as part of a preventative step for a male who does not regularly wear protection during male to male intercourse?

Not really: Truvada (emtricitabine and tenofovir) will cover some strains of HIV only. There is a wide variety of sexual transmitted diseases that Truvada (emtricitabine and tenofovir) will offer no protection against. That' s why mechanical protection in the form of condoms is critical.

Yes, it is.: While every single health care professional rightly says that you MUST wear condoms when having sex with unknown or sero-discordant partners, the reality is that Truvada (emtricitabine and tenofovir) does in fact provide SOME protection from the transmission of HIV. However, we CANNOT condone the use of Truvada (emtricitabine and tenofovir) ALONE, because it does NOT completely protect against HIV, and does NOTHING to prevent ANY OTHER STD.
