Genetic tests predict ED after prostate Therapy

A new study  has identified 12 genetic markers associated with susceptibility for erectile dysfunction following radiotherapy treatment for prostate cancer. Man can use this information to be better inform as to which treatment option might be best for their specific cancer , age and lifestyle.

Researchers involved men with prostate cancer who were randomly assigned to two different groups. Each group of men received brachytherapy, brachytherapy plus external-beam radiation, or external-beam radiation alone, and were followed for 4 years to determine their level of sexual function after therapy.

In a finding that Barry S. Rosenstein, PhD, of the radiation oncology department at Mount Sinai Medical School in New York, New York, and fellow investigators described as notable in their report for International Journal of Radiation Oncology.Biology.Physics, the 12 markers lie in or near genes involved in erectile function or other normal cellular functions  rather than genes involved in DNA damage repair.
