Can HIFU for prostate cancer affect sexual function?

HIFU aims to target only the area of cancer, but the prostate sits close to the nerves involved in erections and ejaculation. This means some men may notice changes after treatment. A small number may experience reduced erectile strength or changes to ejaculation, although side effects are generally less common than with more invasive treatments. Your consultant will review the location of your tumour and discuss your personal risk, so you can make an informed decision about your care.
