Hi, I just thought I'd post a personal experience for parents of boys to be aware of but I doubt many people will need this information. When I was 11, I had a swollen and VERY sore left testicle. The next day I was taken to see the doctor, and by 1pm I was in emergency surgery for a possible twisted testicle, which can kink the blood vessels and restrict blood flow and eventually result in the teste effectively dying. It turned out to be something slightly different (twisted hydatid)... BUT... as well as dealing with the issue the surgeon performed what's called a Bilateral Orchidopexy. This involves attaching the testes to the inside of the scrotum to prevent them from rotating inside. (There are other reasons for this surgery which are also quite valid) Over the last 20 years or so, I've experienced 'twinges' of pain and occasional aches, and I've had to advise sexual partners to be very gentle when it comes to handling my balls. Recently I was on the receiving end of some attention down there, and my partner was being slightly more exuberant than usual. It wasn't painful, it was slightly uncomfortable, but I was enjoying things so I didn't say anything. Since then I've had almost constant aching. I've seen my doctor who has pinpointed the pain as being in the same place as the stitches. I've had a testicular ultrasound and while I'm yet to see my doctor again next week for official results, I've taken a look at the film I was given and the sonographer has put in snapshots labeled as a 'strain'. My doctor is probably going to give me a referral to a urologist to see if I can get the stitches removed. So my point is this: based on my personal experience, this procedure has caused me discomfort and I really don't think it has helped me very much seeing as the chances of getting a twisted testicle aren't all that common. If your son has a similar issue and does need surgical intervention - please check if they intend to perform this procedure and talk to your doctor as to whether they think it's really necessary.
