Patients with cancer and other medical conditions can be rendered infertile by the aggressive therapies needed to control or cure their disease. This is particularly significant in paediatric patients. The number of people choosing to delay starting a family and seeking elective fertility preservation treatments has also increased substantially over the past few decades. Giving these patients the opportunity to preserve their fertility is of the utmost importance and a growing subspeciality of reproductive medicine is dedicated to this cause. This is a practical guide to a range of techniques in fertility preservation, for both men and women, including cryopreservation of gametes, embryos and gonadal tissue, as well as uterine transplantation. Decision-making, ethical considerations and fertility preservation in gender incongruence and paediatric patients are also covered in depth. Written by world-leading experts in the field, gynaecologists, reproductive medicine physicians and oncologists will gain much from this book.
