Background. Couples’ reasons for discarding supernumerary fertilized cryopreserved embryos and gender differences in attitudes toward the frozen embryos were investigated among Swedish couples undergoing in vitro fertilization (IVF) at a private clinic. At the time of the study Swedish law stipulated that couples could keep their frozen embryos for a maximum of one year, with the possibility of an extension based on individual requests. Methods. A questionnaire with structured and unstructured questions was sent to 124 women and 124 men who had entered the IVF treatment and obtained supernumerary embryos from 1 January 1994 to 1 March 1995. Eighty‐two women and 74 men completed the questionnaire. Results. After a mean storage time of 25.3 (±11.0) months 22 (26.8%) of the responding couples had their embryos discarded. The reasons were mainly practical, such as a positive outcome of IVF and a legally too short storage time. Comparisons between women and men showed that fewer women (13;17.6%) than men (20;27%) had been uncertain during the IVF treatment about using the frozen embryos at a later date and that men more often than women expressed anxieties about possible effects of the freezing procedure on the potential child ( p =0.009). Conclusion. A positive outcome of the original IVF treatment and a short maximum legal time of cryopreservation were the most common reasons why couples discarded their embryos. The men more often than women expressed anxieties about possible effects on a potential child. The results emphasize the need for giving detailed information to the couples about cryopreserved embryos and children born by this method.
