Had RP at age 65 followed by salvage radiation and 2 years of Lupron and abiraterone. Finished ADT this past October. RP shortened the penis in flaccid state. ADT caused shrinkage of both penis and testicles. I’m now 4 months out from stopping ADT and genitalia are returning to normal size. I’ve been on 5 mg dose of tadalafil ever since surgery, first to help with healing and then to help address urinary incontinence. Having my genitalia return to normal size is more comfortable and helps when urinating (no fishing for the little bugger), but libido hasn’t returned, and I can’t say I miss it. I used to think about sex all the time. Now I spend my days on other enjoyable pursuits.
