Pain Around the Pelvis
The human pelvis is a complex structure of bones, joints, and muscles. Your pelvis supports your spine and major organs, including your bladder, rectum, intestines, and reproductive system. Some of the most common diseases that affect the pelvis are hernias, bladder infections, kidney stones, appendicitis, constipation, and gastroenteritis. Pelvic pain can also be a symptom of sexually transmitted diseases for males.
When you have an STD, your immune system is compromised, and it cannot fight off certain microorganisms as easily as it normally would. When this happens, these microorganisms can infect parts of your body they normally wouldn’t be able to infect.
One such place is your prostate gland in the pelvic area. The prostate gland is under the bladder and surrounds part of your urethra (the tube urine comes from). The prostate gland secretes fluid into semen that causes it to cling together so that it doesn’t all come out at once when you ejaculate (have an orgasm).
If you have an STD and bacteria get into your semen (which can happen through unprotected sex), they can cause inflammation, swelling, and discomfort in this area.
