Chlamydia is the most common type of STD in the U.S. Some of the symptoms that result from this disease are as follows:
MEN: burning sensation during urination, discharge from the penis or rectum, testicular tenderness or pain, or rectal discharge or pain.
WOMEN: Only about 30% of women with chlamydia have symptoms. Symptoms that may occur in women include: Burning sensation during urination, painful sexual intercourse, rectal pain or discharge, or vaginal discharge.
Chlamydia is spread by vaginal and anal intercourse. Rarely, it is spread during oral sex or by touching your eye with your hand. It can also spread from a woman to her fetus during birth.
Syphilis is a sexually transmitted disease (STD) caused by the bacterium Treponema pallidum. Syphilis is a highly contagious disease spread primarily by sexual activity, including oral and anal sex. Occasionally, the disease can be passed to another person through prolonged kissing or close bodily contact. Signs and symptoms of syphilis include a firm, round, small, and painless sore on the genitals, anus, or mouth, or a rash on the body, especially on the palms of the hands or the soles of the feet.
Gonorrhea is caused by the bacteria Neisseria gonorrhoeae. Anyone who has any type of sex can catch gonorrhea. The infection can be spread by contact with the mouth, vagina, penis, or anus.
Symptoms in men include: Burning and pain while urinating, increased urinary frequency or urgency, discharge from the penis (white, yellow, or green in color), red or swollen opening of penis (urethra), tender or swollen testicles, sore throat (gonococcal pharyngitis.)
Symptoms in women can be very mild or nonspecific, and may be mistaken for another type of infection. They include: Vaginal discharge, burning and pain while urinating, increased urination, sore throat, painful sexual intercourse, severe pain in lower abdomen (if the infection spreads to the fallopian tubes and stomach area), fever (if the infection spreads to the fallopian tubes and stomach area.)
