A microbiologic analysis of my semen revealed that I have E-coli bacteria. The doctor prescribed antibiotics, Ampicillin 500 mg and Gentamicin shots for 1 week treatment. My girlfriend was also tested positive for this bacteria in her vaginal secretion analysis, but her doctor told her that this bacteria is absolutely harmless and she needs no trearment at all.
I think that it would be useless if I take all of the prescribed drugs and clear the bacteria off and my girlfiend doesn't, because when we have sex, I am going to catch the bacteria again.
My doctor told me that my immune system supresses the bacteria and that's why I do not have any symptoms now, but that is not guaranteed in the future. For this reason he believes that immediate treatment with anitiotics is highly recommended.
I would highly appreciate your opinion on this issue. Is this bacteria really harmful, so that it really needs treatment with antibiotics? Is there any danger that it could cause any infection in the future?
