A recent study has revealed that thousands of frozen embryos created through in vitro fertilization (IVF) are discarded when couples separate. The research, conducted at the London Women’s Clinic (LWC), examined cases between 2019 and 2023 and found that two-thirds of couples who ended their relationships after fertility treatment chose to have their remaining embryos destroyed.

Embryo freezing is a common part of the IVF process, allowing couples to preserve embryos for future use if initial cycles are unsuccessful or if they decide to expand their families later. However, when couples who have jointly contributed eggs and sperm to create embryos separate, decisions about the fate of those stored embryos become complex.

Under current regulations, if former partners cannot agree on what to do with remaining embryos, a 12-month cooling-off period is initiated. If no consensus is reached after that time, the embryos are discarded. In cases where only one partner has provided the egg and the other partner's genetic material comes from a donor, the individual who contributed the egg holds the authority to decide on the embryos’ use, including revoking consent for the other partner’s use of the embryos after separation.

The study looked at 141 couples who had frozen embryos at the LWC and subsequently separated. Of these, 66 percent chose embryo disposal, approximately 20 percent decided to retain them, while about 4.2 percent agreed to donate the embryos to their former partner. A smaller number of embryos were donated to other couples undergoing fertility treatment.

Researchers noted that these outcomes underscore the emotional, ethical, and legal challenges involved in managing stored embryos following relationship breakdowns. The findings bring attention to the need for clearer guidance and support around consent and decision-making in the context of IVF treatments when couples part ways.
