Painful Urination

• Infection in the urinary tract by Mycoplasma hominis often results in painful urination for men and women. This infection symptoms is common in most sexually transmitted diseases and can be mistaken for other STDs such as gonorrhea or chlamydia.
  
  

Unusual discharge

• Men and women experience strange discharges a few weeks after contracting Mycoplasma hominis infections. This is because the extra mucus and infected fluids are being excreted by the body, resulting in these unusual--and often foul smelling--discharges.
  
  

Pain during sex

• Women with a Mycoplasma hominis infection will often experience pain during intercourse. This is because the inflammation of the ureter presses upon the vaginal wall. When the vagina is engorged with blood from arousal, the two tissues press against each other. Penetration or sometimes just extreme excitement can result in painful sensations for women. Men do not typically feel pain during sex when infected with Mycoplasma hominis.
  
  

Expert Insight

• Mycoplasma hominis is a common organism and is unlike other sexually transmitted diseases. It is not unusual for monogamous couples to suddenly experience a Mycoplasma hominis infection even after years of exclusivity. In these cases, there are other factors at work that make infection by this common microbe more likely, such as suppressed immune systems.
  
  

Warning

• People with suppressed immune systems, such as those with HIV/AIDS or who have recently undergone an organ transplant, are more likely to contract this unusual venereal disease. In some cases, Mycoplasma hominis can affect organs outside the urinary or mucus tracts. For example, patients who have experienced renal failure after a kidney transplant might have been affected by a Mycoplasma hominis infection in the kidneys.
