  • Chlamydia
    A common STD that can infect both men and women. It can cause serious, permanent damage to a woman's reproductive system, making it difficult or impossible for her to get pregnant later on. Chlamydia can also cause a potentially fatal ectopic pregnancy (pregnancy that occurs outside the womb).

  • Condoms and lube
    Condoms and other barriers, when used consistently and correctly, greatly reduce the risk of HIV and other STDs. Most condom failures result from incorrect use of the condom, not because the condom itself was faulty.
