  • This is the most common infectious disease and STD reported in the U.S.
    • 3-5 million new cases each year.
    • Adolescents are very vulnerable.


Chlamydia is a disease usually occurring inside of your body and usually starts inside your penis, causing an infection of the urethra, which is the tube down the middle of your penis that carries urine out of your body.

  • Takes 3-5 days (up to 30 days) before a guy will notice symptoms in his penis.
  • Ejaculation is not needed to catch it or pass it.
  • 80% of women have no symptoms at all even though they are infected, therefore they may not know that they are giving you the same disease.
  • Disease can be transmitted to someone else before symptoms occur.


Almost same symptoms as Gonohrrea.

  • May take 2-3 weeks after exposure before symptoms occur in the penis.
  • Women rarely (20%) have symptoms.
    • 40% will get PID, and 20% of these may become infertile (unable to ever have a baby).
    • 18% have extreme chronic pain
    • 9% may suffer a life-threatening complication of pregnancy called a tubal pregnancy
  • Can be passed when no symptoms are present.


  • Antibiotics correctly chosen by your doctor will easily cure the disease.
  • No over-the-counter medicine works, only the correct antibiotic, so see a doctor.
