Mild rectal bleeding is a common side effect following a prostate biopsy procedure, explains Mayo Clinic. Men may also notice small amounts of blood in the urine and stools, as well as a rusty tint in the semen.
It is important for men to avoid activities that require heavy lifting and abstain from sexual activities for 48 hours following prostate biopsy procedures, explains WakeMed Physician Practices. After a prostate biopsy, patients are provided with antibiotics to help prevent infection, but it is still a possibility. Patients should contact their physicians immediately if they experience continual rectal bleeding or develop a fever of 101 degrees Fahrenheit or higher.
