Not everyone loves condoms. But here's another reason to make like the Rio Olympics and stock up. Certain sexually transmitted diseases are developing a resistance to antibiotics, making them harder to treat, according to a new report from the World Health Organization (WHO).

Earlier this summer, the Centers for Disease Control and Prevention (CDC) reported that gonorrhea was becoming resistant to antibiotics. And now the WHO added chlamydia and syphilis (which apparently still exists) to the list. This means all three could be more difficult to treat, and if not treated, they could lead to health problems. Especially for women.
