Once you stop ADT, your testosterone may return to where it was before, a lower level than before or not at all. Many of the side effects of ADT are the result of low or absent testosterone, not the drugs. I think it is important to deal with this now, rather than later. I was fine after my radical prostatectomy but ADT gave me ED. I tried Sildenafil and Tadalafil as well as Trimix. None of them worked well enough. Since I never lost my libido, I got a IPP (inflatable penile prosthesis) implant a year ago. My wife and I continued to have regular sex without penetration for the three years I was on ADT before my IPP. We are both very happy with the implant. I am 74 and have had PC for almost 10 years. I have been off ADT for 14 months and my testosterone is coming back very slowly.
