Medical techniques of fertility preservation in the male and female.

Therapeutic advances in many medical fields have led to the need to consider patient quality of life after curative medico-surgical treatments for malignancy. Thus, it has become a major issue for young patients to preserve the ability to become "genetic" parents, with their own gametes. While the preservation of male fertility has been an established technique for more than 30 years, it is only in the last decade that progress in cryopreservation techniques has allowed surgeons to offer successful oocyte and ovarian tissue cryobanking. However, in addition to the still experimental nature of some fertility preservation techniques, this practice also raises many ethical and moral questions.
