<s>[INST] my boyfriend is 27 and had had discomfort in the groin and blood in his urin he was told its a prostate infection and was perscribed doxycycline hyc 100 mg for 21 days.... im concerned about me though because he has recently told me when he was 16 he had the clap is there a possibility he's got it back?  Ive never hurd of someone his age with prostate problems.... [/INST] Thanks for contacting HCM. You are concerned about your boyfriend having had gonorrhea when he was 16 could still give you gonorrhea after all these years. The short answer is not likely. Gonorrhea would have been an active infection for nearly a decade and that is not possible. What is possible even for a young adult prostatitis can occur. I recommend that he complete his antibiotics and follows up with his doctor o be sure it has resolved. There is no chance for you to get the same infection from prostatitis. Hope this answers your medical question. Please contact us again with your health care concerns and questions </s>
