title: [Freezing of human embryos. A review of and a suggestion to unified guidelines for treatment at public fertility clinics in Denmark].
abstract: In Denmark, legislation has made cryopreservation of human oocytes and embryos possible since October 1992. The legislation is reviewed. Cryopreservation of embryos constitutes a significant improvement of infertility treatment. The number of oocyte pick-ups and the number of embryos transferred can be reduced without compromising the total likelihood of success of in-vitro fertilization (IVF) treatment. According to Danish law, frozen embryos can only be stored for one year. This limit will interfere with patient expectations in numerous cases, and the time limit should be expanded. Moreover, freezing of embryos should be allowed in connection with oocyte donation programmes.
