Male cancer survivors may soon be given hormone replacement therapy to restore their testosterone levels after treatment.
Scientists at the University of Sheffield are about to begin a trial which will involve giving male cancer patients between the ages of 25 to 50 a gel which is absorbed through the skin.
The testosterone replacement strategy will be compared against a placebo gel by measuring the potential side effects of cancer treatment such as weight gain, less energy and a low sex drive.
It is hoped that the results could be used to develop a treatment to help the estimated 23,800 men in the UK who have low levels of testosterone following cancer treatment.
Cancer Research UK's director of clinical research Kate Law said it is rare for men to be diagnosed with cancer at a young age, but if so they are more likely to survive.
"Many of these men will have long-term side effects as the result of their treatment, so finding a way to ease these symptoms is potentially very exciting, because it could really improve the quality of life for thousands of men in the UK," she added
