A latest study has revealed that men who end up surviving cancer, those who were treated with chemotherapy or radiotherapy, could end up developing a deficiency of the hormone testosterone, which further tends to negatively affect their quality of life and can leave then feeling lethargic.

As has been revealed by the study, nearly 15% of the male cancer survivors go on to develop the deficiency of testosterone.

The link between the levels of testosterone and quality of life in males, sexual function and fatigue was analyzed by lead researcher Prof. Richard Ross, of Sheffield University, in as many as 176 cancer survivors and 213 healthy males of the same ages.

"This is an important study demonstrating that low testosterone levels are common in male cancer survivors and associated with an impaired quality of life. We now need interventional trials with testosterone to determine which young male cancer survivors will benefit from replacement therapy", said Prof. Ross.

Details of the study have been published in the journal Cancer.
