O-23: Transfer of Blastocysts Derived from Frozen Thawed Cleavage Stage Embryos Improved Ongoing Pregnancy
Background: The aim of our study was to compare the resulting from transfer of embryos that cryopereserved in cleavage stage after thawing and transfer of embryos after thawing and culture in sequentional media until blastocyst formation. Materials and Methods: In this prospective clinical study, we have evaluated 128 cycles in women undergone in vitro fertilization (IVF) or intracytoplasmic sp...
متن کاملBetter perinatal outcomes following transfer of fresh blastocysts and blastocysts cultured from thawed cleavage embryos: a population-based study.
BACKGROUND Fresh embryo transfer results in higher live birth rates, while thawed embryo transfer appears to result in healthier babies. This study aims to investigate the association between the transfer of fresh or thawed embryos at the cleavage or blastocyst stage and the perinatal outcomes. METHODS This analysis is a retrospective population-based study of 150 376 autologous embryo transf...
متن کاملTelomere lengths in human oocytes, cleavage stage embryos and blastocysts
Telomeres are repeated sequences that protect the ends of chromosomes and harbour DNA repair proteins. Telomeres shorten during each cell division in the absence of telomerase. When telomere length becomes critically short, cell senescence occurs. Telomere length therefore reflects both cellular ageing and capacity for division. We have measured telomere length in human germinal vesicle (GV) oo...
متن کاملThe Analysis of Factors Affecting the Success Rate of Frozen Thawed Embryos in IVF / ICSI Cycles
Purpose: the aim of this study is to analyze the factors contributing to the success of frozen- thawed embryo transfer (ET). Material and method: This retrospective, case-control study was carried out on 700 infertile couples treated with IVF and ICSI and had embryo freezing in Isfahan Fertility and Infertility Center, Iran, from the beginning of July 2000 to the end of June 2003. Results: fa...
متن کاملHeat shock decreases the embryonic quality of frozen-thawed bovine blastocysts produced in vitro
In this study, the effect of heat shock on frozen-thawed blastocysts was evaluated using in vitro-produced (IVP) bovine embryos. In experiment 1, the effects of 6 h of heat shock at 41.0 C on fresh blastocysts were evaluated. HSPA1A expression as a reflection of stress was increased by heat shock (P < 0.05), but the expressions of the quality markers IFNT and POU5F1 were not affected. In experi...
