There are several types of chronic prostatitis, with nonbacterial prostatitis being the most common clinically. This type of prostatitis is not contagious during sexual activity, so there is no need for concern. However, chronic bacterial prostatitis can potentially be contagious, particularly when caused by Mycoplasma or Chlamydia infections. These pathogens can travel with semen into the female vagina, leading to vaginitis. Therefore, it is best for patients with prostatitis to undergo prostate fluid culture and sensitivity tests to determine the specific type, followed by targeted treatment.
