Karen Cormier, 39, developed a rare form of kidney cancer when she was 5 years old, underwent chemotherapy, got cured with near certainty that she would be infertile. Two years of trying to conceive without success,  she and her husband ended the fertility treatments and adopted a son. Then, three years later, the unthinkable happened: Cormier discovered she was pregnant. She gave birth to a son.

For children with cancer, chemotherapy and radiation treatments are a double-edged sword, one that is lifesaving but often toxic to the fast growing cells of the reproductive system. Many children who live through cancer struggle to conceive once they reach adulthood. Clinical infertility, the failure to conceive after a year of trying, is particularly common among adults who received pelvic radiation and a class of chemotherapy drugs called alkylating agents. In some cases, when stem cell transplants and especially high doses of radiation are used, children may be left completely sterile.

But today, doctors are offering patients preservation options at the time of diagnosis, and researchers are finding that for many survivors, the odds of overcoming clinical infertility are surprisingly good.

Going by recent studies, doctors say that while there is no doubt that childhood cancer increases the likelihood of infertility, the ovaries and testes of young cancer patients may be more resilient than they had previously thought.
