Please tell me what does a prostate biopsy entail and what can i expect afterwards?

Biopsy: Most prostate biopsies are done with you lying on your side, an ultrasound probe placed in the rectum through which numbing medicine can be administered around the prostate prior to taking small needle samples of the prostate, again through the ultrasound probe. Patients give themselves an enema at home prior to the biopsy, and take antibiotics before and after the biopsy for safety.
