I am 29 years of age. I am here to discuss my problem with all of you. I am married for 5 years now. I have a healthy sex life with my wife. But for the last one week I am confronting this swollen testicle problem. There is pain and swelling in my right testicle with redness surrounding the complete area including the scrotum. Could this be an infection due to the intercourse or is this something else. I am interested to know the causes for swollen testicle?
