LHRHa during chemotherapy, could protect women's ovaries.

Young women undergoing chemotherapy for breast cancer may be more likely to remain fertile if they also receive hormonal treatment, according to new research presented to the 2015 European Cancer Congress on Monday and published simultaneously in Annals of Oncology.

Researchers will tell the Congress that the addition of treatment with a so-called luteinising hormone-releasing hormone analogue, or LHRHa, during chemotherapy, could protect women's ovaries. The approach may increase the chances of pregnancy after breast cancer treatment.
