As a result of the inability of female germ cells to regenerate after injury, a number of chemotherapeutic agents induce premature ovarian failure in the majority of reproductive age women who receive them. The long-term survival for these women has increased with more effective chemotherapies, making iatrogenic ovarian failure and infertility an increasingly significant issue. Currently the choices for maintaining fertility include in vitro fertilization (IVF) and embryo cryopreservation, oocyte cryopreservation and the use of GnRH agonist and antagonist to preserve ovarian function.
