The problem of orgasm after the recovery of sexual ability varies from person to person, some people can recover the same as in the past, but some people will have an orgasm when the semen is not discharged from the urethra, but reverse into the bladder, that is, reverse ejaculation, that is because when the prostate is removed, the surgical scar will cause muscle contraction, resulting in changes in the urethral ridge. The result is that the ejaculatory ducts change from pointing at the urethra to pointing at the bladder, so that there is a “reverse ejaculation” during sexual intercourse, which has little effect on the elderly because they are no longer fertile, and there is no damage to the body.
