All patients where the cancer treatment has gonadotoxic potential should be referred for oncofertility advice. The effect of chemotherapy and radiotherapy on the human ovary can vary from no impact to full-blown premature ovarian failure due to hormonal and follicular depletion.

Doxorubicin (DOX) has been widely used as a cytotoxic chemotherapeutic. However, DOX has a number of side effects, such as myelotoxicity or gonadotoxicity, the most dangerous of which is cardiotoxicity. Cardiotoxicity can manifest as cardiac arrhythmias, myocarditis, and pericarditis; life-threatening late cardiotoxicity can result in heart failure months or years after the completion of chemotherapy.

Alkylating chemotherapy (AC) is known to be more gonadotoxic than non-alkylating chemotherapy (NAC). Anti-Müllerian hormone (AMH), an indirect marker of ovarian reserve, and age have been investigated as predictors of ovarian function after chemotherapy; however, little is known about the time to return of menses.
