I didn’t say it could not be herpes. I said I rarely see herpes on the testicle and that is true for me, regardless of what it says on the Planned Parenthood websiste. I specialized in genital herpes infection for 33 years, seeing thousands of patients and that is the experience that I am reporting to you. Have I seen it? Yes, just rarely. You said you were tested and do not have HSV 2. is that IgM, IgG, swab test? and if IgG, how long after the last sexual encounter did you get tested? It can take up to 12 weeks for an antibody test to become positive, after a new infection.
