Social Freezing

Putting childbearing on ice – Expert study


«Social freezing» refers to the practice of harvesting and freezing a woman’s eggs (cryopreservation) so they can be used for a pregnancy later in life. Thus, women who do not suffer from any underlying infertility problems are making use of reproductive medicine solely for the purpose of postponing the start of a family – either for career reasons or because they have not yet found the right partner, for example. Mature eggs from the woman’s ovaries are extracted, frozen and stored. Years later the frozen eggs can be thawed and then fertilised in vitro. This technology promises to free women from the dictates of their biological clock, but it also raises questions about medical risks, child welfare and society's efforts to make career and family compatible.

This interdisciplinary study evaluates the risks and rewards of social freezing. It examines how many women in Switzerland avail themselves of social freezing, how great the future potential of this technology is and what changes it would bring about as compared to today. It addresses the points that should be covered in a medical consultation regarding egg harvesting and subsequent in vitro fertilisation and embryo implantation, as well as the legal, ethical, social and medical standards that should apply to the fertilisation of human eggs and implantation of human embryos.

It concludes with an overall evaluation. Based on this, recommendations directed at decision-makers, in particular politicians, are formulated accordingly.
