A new Australian study shows that a significant number of cancer patients are not being told their treatment can cause infertility.

In a survey of 878 cancer survivors, just 46 per cent of men and 57 per cent of women reported their practitioners discussed with them the possibility of treatment causing infertility. 

Results from the study led by Western Sydney University showed doctors are focused on treating cancer and they often believe potential side effects of treatment to be out of their scope, or too time-consuming to deal with.
