Asymptomatic STDs: The Hidden Epidemic

Perhaps you've heard someone say, "I don't need to get tested for STDs. I'd know if I had one." Perhaps that someone was you. Unfortunately, it simply isn't true -- the vast majority of people with sexually transmitted diseases never know they have them until it's too late. What is too late? It varies for different people. Too late could be when you try to have a child and discover that untreated chlamydia has rendered you infertile, or it could simply be hearing that you've passed on a disease to someone you love.
