Prostatitis means infection or inflammation in prostate. Inflammation, according to wikipedia, is part of the complex biological response of vascular tissues to harmful stimuli, such as pathogens, damaged cells, or irritants. When prostate get infected, there must be bacteria or pathogens in prostate fluids, which can enter into vagina during intercourse as a part of semen. Then bacteria or pathogens entering into vagina can cause infection or inflammation. This is the point view that many people hold. But it is true?
Actually, this question can't be anwsered simply by "Yes" or "No". First, you should know clearly about the type of your prostatitis. Clinically there is no bacteria found in 90% of prostatitis, which means it is non bacterial prostatitis. If a man has this type of prostatitis, the infection can't be trasnmitted to a woman.
Another situation is that a small percentage of prostatitis is caused by trichomonas or fungus infection. Other pathogens such as neisseria gonorrhoeae, mycoplasma and chlamydia can also lead to prostate infection, which is called bacterial prostatitis in clinic. These causing factors are infectious to some extent.
However, whether bacteria can cause women get infected are based on many factors, such as the strength of the bacterial virulence, the number of bacteria, the partner's resistance etc. If prostatitis is in an acute stage, the the possibility of women getting infected is high. On the other hand, vagina is an acidic environment which has certain lethality to bacteria. As long as the strength and quantity of bacteria is not high, prostate infection can't make women get infected.
No matter what prostatitis it is, men with prostate infection should take correct medication in time. For acute prostatitis, antibiotics are the first choice. But if antibiotics don't work, and the disease develop to chronic, then men need to take herbal medicine Diuretic and anti-inflammatory Pill to cure chronic prostatitis. In general, patients with prostatitis can get cured with the pills in three months.
