Women in Western societies have been progressively postponing the birth of their first child. However, the human body has not always accommodated the new professional and personal challenges women have faced. It has therefore not been uncommon for women to discover that it is simply too late for them to become pregnant. To overcome the obstacles that biology imposes on female reproduction, women have resorted to oocyte cryopreservation. This procedure was originally used by patients with a risk of becoming infertile from medical treatments. Now it is increasingly being used to expand reproductive age. Although oocyte cryopreservation presents several advantages in light of other possible reproductive options for older women, such as oocyte donation and embryo cryopreservation, it still raises many legal, medical and ethical concerns. From a medical perspective the main concerns are the risks for the woman (oocyte extraction) and for offspring (oocyte cryopreservation). Ethically it has been argued that this medical procedure is nothing but the fulfilment of a whim, at the expenses of the violation of natural boundaries to human reproduction, resulting in contra natura practices. From a juridical standpoint it is clear that there are still many questions that need to be legally solved: time limit for oocyte cryopreservation, consequences of the oocytes’ holder death, lawfulness of oocyte donation (in life or after death), compensation in case of oocyte destruction, requirements of patients’ informed consent and legal limitations that may prevent women from using cryopreserved oocytes. All these are issues which are addressed in the paper.
