  • Zamrzovanje in odmrzovanje zarodkov v programu zunajtelesne oploditve = Embryo freezing and thawing in program of in vitro fertilization
    Virant-Klun, Irma ...
    Background. Upon obtaining the written informed consent from the couple, the surplus embryos, resulting from in vitro fertilization procedure (IVF) at the Department of Obstetrics and Gynaecology ... Ljubljana, were frozen and stored. The frozen embryos of the patients who failed to conceive with fresh embryos, were thawed and transferred into the uterus. Methods. After pre-treatment of freezing solutions with succrose and cryoprotectant, embryos were stepwisely frozen to - 150 degrees C and stored in liquid nitrogen at - 196 degrees C. Onthe day of embryo transfer into the uterus (ET) embryos were thawed at room ature in the series of thawing solutions. Asfeered into the uterus. For ovulation stimulation patients were pre-treated with human menopausal gonadotropins hMG (Pergonal, Serono) in doses which enabled developing as low number of preovulatory follicles as possible. Then, we waited for a natural ovulation, or it was induced by human chorionic gonadotropins (hCG). In patients with previous prooved ovulation cycles, the thawed embryos were transferred into the uterus in the spontaneous, non-stimulated cycle. Results.Until 1st February 1998 we froze 1410 embryos of 437 female patients, 3 embryos per patient on the average. The results of embryo thawing obtaine din the time period December 1996 - February 1998 were analysed. In this time period 110 embryo thawing cycles were performed in 110 patients. We thawed 302embryos. 194 (64%) of embryos survived freezing and thawing processes.(Abstract truncated at 2000 characters)
