Abstract
Objective: This review aimed to investigate and summarize the current evidence on fertility-sparing options in cancer patients. Mechanism: Fertility preservation methods are becoming popular through the improved prognosis of cancer patients at a younger age and early diagnostic tools. However, currently, more and more women are suffering from iatrogenic ovarian failure and fertility loss because of cancer treatment. Most treatments have been used for hematological malignancies, but different gynecological cancers can be eligible. Findings in brief: Fertility preserving strategies such as oocyte and embryo cryopreservation, ovarian tissue preservation, ovarian transposition, and aspiration of ovarian follicles are the methods that could be suggested to the patients. The current knowledge supports oocyte and embryo cryopreservation as feasible, safe, and effective treatment approaches for cancer patients seeking fertility preservation. Conclusions: Robust evidence is still needed to prove the effectiveness of cryopreservation of the ovarian tissue and ovarian follicle aspiration approaches since these techniques are still in early their steps.
