Impact of Peri-operative tEstosterone Levels on oNcological and Functional Outcomes in RadiCal prostatEctomy

This study is investigating whether testosterone levels before and after surgery to remove the prostate (radical prostatectomy) affect cancer outcomes and sexual function recovery. Testosterone deficiency is common in men with prostate cancer, and researchers want to know if it impacts how well surgery works and how quickly men recover. **You may be eligible if...** - You are a male 18 years or older - You have been diagnosed with prostate cancer, confirmed by biopsy - You are having radical prostatectomy as your primary treatment - At least one nerve bundle beside the prostate is being spared during surgery - Your cancer has not spread (confirmed by imaging) - Your PSA (prostate-specific antigen) is undetectable after surgery - You have testosterone deficiency (confirmed by blood tests on two separate occasions) - You had some sexual function before surgery **You may NOT be eligible if...** - Your prostate cancer has spread to other organs - Your PSA was detectable after surgery - You have no testosterone deficiency - You had prior prostate treatment before this surgery Talk to your doctor to see if this trial is right for you.
