Fertility preservation (FP) is to cryopreserve embryo gametes or reproductive tissue for people on the risk of fertility deterioration. It can be divided into medical and social. Medical FP refers mostly to the chemotherapy or radiotherapy which can destroy reproductive tissue. Social FP refers mostly to the women in advanced age whose fertility can be compromised leading to menopause. Our aim was to discuss the ethical and legal issues of FP.

This study has been done by using documentary- library. Information was collected from legal and ethical books and papers, Persian and English papers, declarations about the subject, data bases. In addition legal analyses have also been done in legal aspect issue.

As FP is a new issue, its permission depends on non-existence of ethical and legal prohibition. We should say that there is no prohibition on this matter according to ethics and law.

There are some ethical arguments against FP, such as potential threat for child, biological boundaries, and preventing harm prior to every action. Of course all of them have been answered. There are some legal arguments such as, principle of permissibility, reproductive right and prevention from chromosomal problems for permission of this act. Finally it seems that FP lacks ethical or legal problem.
