BOOK TITLE: Principles and Practice of Assisted Reproductive Technology
Fertility preservation can be defined as a means for preserving an individual’s ability to reproduce at will or at a chosen time. It has given a new dimension to ART services. With a post-thaw embryo/gamete survival rate of around 90%, and around 50% implantation rate, the infertility specialists confidently offer freezing to all who want to delay childbearing or whose fertility is at risk. Fertility can be preserved in many ways for these patients, though some are established and some are emerging. Embryo/oocyte and semen cryopreservation are well accepted methods of fertility preservation in postpubertal patients. This chapter covers the role of fertility specialist and oncologist in fertility preservation, indications of fertility preservation, techniques of fertility preservation, emerging technologies, recommendations for fertility preservation in cancer patients, posthumous use of stored reproductive tissue or gametes, and avoiding cancer in offspring.
