What causes swollen testicle's epididymis?
Patient: My left testicle's epididymis felt a bit swollen and sore earlier today.  It feels a bit better now.  I was wondering if it might be because I've held off from ejaculating while masterbating this week (I've been edging in hopes of saving my semen for a wet dream), or if it might be more serious.  Thanks! Doctor: Hi,  Yes, you can have pain if you are stopping the release of sperm during ejaculation, which can cause retrograde flow. Yes, it can cause infection and injury to your prostate. It is a very odd or injurious way to get wet dreams.  Hope I have answered your query. Let me know if I can assist you further.  Regards, Dr. S.R.Raveendran, Sexologist
