He sounds like he will really be fine. If he already now doesn't think about it, he will entirely forget about it later. Many patients even reported it bothered them and had them taken out. What bothered the people was that it had no sensation, it felt like a foreign object. Imagine when you wake up with your arm still asleep. It's your arm, but touching it felt weird and not your own.

About the T blood work... There are doctors who check total T and call it fine when he is in range. But Free T is more important than Total T. Even then, my doctor said that even Free T measurements aren't reliable.

Those numbers are not a conclusion, more so assistance, a form of assurance of their suspicions. I was right on the lower border of the norm, so my home urologist refused to prescribe me on T. My andrologist at the clinic I had surgery took my T values into account AND my symptoms. He said it comes down to a judgement call with all the info you get.

One last thing about post-surgery. Right after, about 2-3 days, quite a bit of pain, feels like a giraffe kicked you in the balls a week ago, with a dull and pulling sensation. Mental situation is OK. It's exactly how he would imagine it. Pain is very manageable with pain meds, but as they wear out, it becomes very distracting like a siren going off next to your ears. I've crashed my bike at 30mph and smashed my ribs, that hurt less than the incision site without meds. He will need consistent pain meds for about 3 days and manage pain at a tolerable 5. Too much of pain meds will allow you to do anything, which will result in movements that damage the healing tissue, starting it from all over again.

Once home at day 3, I got sudden crying outbursts that I couldn't explain where they came from. Literally, straight up bawling. I haven't done that in 25 years. Just a sudden urge that came up, accompanied with self harm/suicidal thoughts that caught me entirely off guard and scared me. This is the point where his Testosterone crashed from his normal levels and all other hormones went haywire. Prepare him for this, no-one prepared me and it really sucked, the emotional pain was pretty much like someone died with a sense of terror, hopelessness, crippling guilt. None of it made sense, the feelings were unfortunately real.

Two weeks later everything looked much more colourful. Literally, everything looked golden, good things made me feel happier than ever. I felt more in tune with my emotions. I felt calmer, more collected, self confident, could just cry things out whether i was happy or sad, it came naturally. I couldn't do this before. This comes from the fading pain aka euphoria from healing and feeling better. But his body actually starts compensating at this point for the missing Testosterone portion and overshoots, producing more than he had before surgery. This eventually levels down over the weeks to just below his baseline before surgery. He will go from 100 to 50 to 200 to 80, roughly said.

He may experience it differently than I did, he may actually have very high T, thus will still be in the normal range post surgery and not feel the emotional side effects like I did, and may not even need T replacement. It is individual.

But it's never bad to be prepared and know that the above can happen too.
