Fertility preservation and reproduction in patients facing gonadotoxic therapies: a committee opinion.

Chemotherapy and radiation therapy often result in reduced fertility, and patients receiving gonadotoxic treatment should be informed of options for fertility preservation and future reproduction prior to such treatment. Reproduction in the context of cancer also raises a number of ethical issues related to the welfare of both patients and offspring. This document replaces the document titled, "Fertility preservation and reproduction in cancer patients," last published in 2005 (Fertil Steril 2005;83:1622-8).
