I've been dealing with mild penis injury, what I believe is mild Peyronie's for three years. Have not been as sexually active due to the pain. I may be imaging things but it sounds/feels like my voice is not as deep as it used to be. Has this happened to anyone else?
Prob best just to get your hormone levels checked.
It's always good to get your hormone levels checked, but I don't think your voice can get higher after puberty. Also, I have been on testosterone myself and it made no difference in erection quality and for peyronies symptoms. There may be a connection between low testosterone and peyronies, but it isn't a very strong one I think.
