I'm a 26 year old who's been suffering from prostatitis for a year now. After a visit to my 3rd urologist (first 2 just gave me antibiotics and didn't do much), the doc did a semen culture. I talked to him today and he told me that I had a light growth of staph in my semen. He asked me if I was symptomatic, at which point I was (I become symptomatic for about 1-2 weeks every 6 weeks or so). He said if I wasn't symptomatic, he wouldn't prescribe me antibiotics, but since I was, he gave me an antibiotic for 2 weeks.
My question is, is this an infection I should be concerned about as far as passing it to my g/f during sex? My urologist told me that it's not an STD, but I'm not sure at this point. My doc said anyone can have this infection and it's usually normally found in the genital area anyway. Can it cause infertility?
