Vitrification of preimplantation genetically diagnosed human blastocysts and its contribution to the cumulative ongoing pregnancy rate per cycle by u…
2008
Objective To evaluate the survival rate and clinical results of our vitrification procedure on preimplantation genetic diagnosis (PGD) blastocysts and to calculate its actual contribution to the reproductive outcome per cycle. Design Retrospective clinical study. Setting University Institute IVI, Valencia, Spain. Patient(s) Patients who requested cryotransfer of surplus PGD blastocysts after failed fresh elective transfer. Intervention(s) Retrospectively collected data during 2 years of experience with blastocyst vitrification. Main Outcome Measure(s) Primary outcome measures were the following: blastocyst recovery and survival; cryotransfer cancellation; and the implantation, pregnancy (PR…
Ultrastructure of preimplantation genetic diagnosis-derived human blastocysts grown in a coculture system after vitrification
2006
Objective To evaluate ultrastructural features of preimplantation genetic diagnosis (PGD) blastocysts before and after vitrification. Design Descriptive study of both vitrified and fresh hatching blastocysts. Setting PGD program at the Instituto Universitario, Instituto Valenciano de Infertilidad. Patient(s) Patients undergoing PGD donated their abnormal embryos for research (n = 26). Intervention(s) Biopsied embryos were cultured in the presence of human endometrial cells until day 6. Sixteen blastocysts were vitrified. A total of 11 high-scored hatching blastocysts, 6 warmed and 5 fresh, were fixed for ultrastructure. Main Outcome Measure(s) The cytoskeleton structure, type of intercellul…
