After radical prostatectomy for prostate cancer, there is sexual desire but inability to have an erection, which may be related to surgical complications and drug effects.
1. Surgical complications: radical prostatectomy for prostate cancer does not affect the testicles, and a considerable level of androgen exists in the body, so sexual desire can be produced normally. Radical prostatectomy for prostate cancer may damage the blood vessels and nerves innervating the penis, leading to the emergence of postoperative erectile dysfunction, with sexual desire but unable to have a normal erection.
According to the early and late staging of the patient’s tumor, preoperative radical prostatectomy with preservation of erectile function can be chosen appropriately.
2. Drug effect: for patients who have used endocrine therapy for prostate cancer before operation, anti-androgen therapy is carried out, which affects the androgen level of patients, and the phenomenon of having sexual desire but unable to have an erection will occur.
After radical prostatectomy for prostate cancer, you can go to the hospital in time to see a doctor and get a clear cause for targeted treatment.
