The question "Will treatment make me impotent?" is on the minds of many patients undergoing treatment for prostate cancer. Erectile dysfunction caused by trauma to the nerves and blood vessels involved in sexual function affects about half of men receiving radiation therapy to treat prostate cancer. "Nowadays, mortality after treatment for localized prostate cancer is as low as 1 percent at 10 years," Neil Desai, assistant professor of radiation oncology and principal investigator of the POTEN-C trial, said in a press release. "By contrast, as many as half of all patients being treated for prostate cancer will experience some decline in sexual function. It is appropriate, therefore, that our focus has shifted to this aspect of quality of life," he added. The POTEN-C trial (NCT03525262) is currently testing a new technique to limit the amount of radiation applied to the side of the prostate that shows no signs of cancer to spare nerves and blood vessels in that region. To achieve this, patients will first receive stereotactic ablative radiotherapy (SAbR) – a highl
