Oocyte vitrification for elective fertility preservation: a SWOT analysis.

Oocyte vitrification, also known as egg freezing, is increasingly being used by women as a precautionary measure against the anticipated decline in fertility. In countries where this procedure is allowed, elective oocyte vitrification has become an integral part of the treatment portfolio of fertility clinics. The widespread tendency towards the postponement of motherhood and the advances in laboratory technologies are encouraging women to consider oocyte vitrification and, by doing so, increase their reproductive autonomy. However, elective oocyte vitrification, or elective egg freezing (EEF), still elicits controversy, not only when EEF is appraised from a cost-efficiency point of view, but also in terms of medical and ethical concerns. In general, although the laboratory tool of vitrification has revolutionized the treatment of infertility, the pros and cons need to be clarified when considering EEF.
