Ethical quandaries in gamete-embryo cryopreservation related to oncofertility.

While cancer rates continue to increase, therapy has dramatically decreased the mortality rates. The increased efficacy of current therapies may unfortunately have profound toxic effects on gamete function in both adolescent and reproductive age groups, with infertility as an expected consequence of cancer therapy. Significant progress in the advancement of fertility preservation therapies provides realistic options for future fertility in cancer survivors. However, a number of challenging issues need to be considered when presenting fertility preservation options. This overview highlights some of these considerations including religious-cultural-ethical values, access to care and cost of services, developmental capacity and consent, and posthumous reproduction.
