A common treatment for prostate cancer is surgery to remove the prostate gland. This is a radical prostatectomy.

glands that produce semen - these are the seminal vesicles
After surgery to remove your prostate, you no longer ejaculate semen. This is because the prostate makes most of the fluid in semen. Your testicles continue to make sperm cells but they are reabsorbed back into your body. This means you are still able to have an orgasm, but this is a dry orgasm with no ejaculation.
This means you will not be able to get someone pregnant by sexual intercourse.
