Since the first week of TRT I have noticed that a lot of the time my scrotum is very tight. This is very unusual, since normally it would be very loose. Testicle size seems okay, but they are just drawn tight. I have been taking 250IU HCG EOD since the start. Thinking that might not be enough, I raised this to 400IU EOD for the last 2 injections, but that does not seem to make a difference yet to the tightness, so I am not sure insufficient HCG is the problem. Is there any other reason why TRT would cause this?
