The Ethical Issues of Oocyte Cryopreservation
Xiao-wei LU, Yun FENG*
[ABSTRACT] With the development of assisted reproductive technology, human oocyte cryopreservation brings benefits to the women as follows: who may lose ovary function after surgery or radiotherapy and chemotherapy; who may gain premature ovarian failure; who have collected oocytes after ovarian hyperstimulation but the husband failed to gain sperm; who will delay their reproductive age due to various reasons; and those who are waiting for donate eggs. At the same time, the technology has also brought ethical arguments: Shall we provide egg freezing services to single women? Who have the right of the frozen eggs? Whether the women or their offsprings have the right to know the information about the children or the biological mother? We suggest that the agencies should give all the information about limitations of oocyte cryopreservation, possible risks, and so on, provide psychological assessment and pre-determine the ownership of the eggs before freezing. And the assisted reproductive institutions should follow the principles, as beneficial to patients, informed consent, protecting the offspring, public welfare, confidentiality, without commercialization and ethical oversight, in the process of consultation and oocyte cryopreservation.
