title: [Cryopreservation of embryos in an in vitro fertilization program(IVN-ET)--preliminary results].
abstract: The authors present preliminary results of cryopreservation of embryos in IVF-ET programme in the Institute of Obstetrics and Gynecology in Białystok. The method of slow cooling embryos with 1, 2 propanediol and saccharose were used. In the group of 136 patients with excess embryos after the transfer of two fresh embryos 29 pregnancies (21.3%) were obtained. After the transfer of frozen/thawed embryos up till now 5 pregnancies have been obtained (one child born, 3 pregnancies ongoing, 1 abortion).
