Protection vs. Birth Control vs. Contraception: What's the Difference?

Contraception and birth control are essentially synonyms — methods specifically aimed at preventing pregnancy. This includes hormonal methods (the pill, IUDs, implants), which prevent pregnancy but provide no protection against STDs at all. "Protection," in the context of sexual health, more specifically refers to barrier methods — external and internal condoms — which are the only category on this list that meaningfully reduces STD transmission risk alongside preventing pregnancy.

Being on hormonal birth control (the pill, an IUD, an implant) provides no STD protection whatsoever — this is a common and genuinely consequential misunderstanding, since these methods are highly effective for pregnancy prevention specifically, which can create a false sense of "being protected" more broadly. If STD prevention matters alongside pregnancy prevention, that requires a barrier method (condoms) used consistently, regardless of whatever hormonal method might also be in use.
