introduction: it is now generally accepted that vero cells provide beneficial effects on improving embryo quality in many animal species. the aim of this research was to determine the effect of vero cell co-culture on the development of vitrified 8-cell mouse embryos. material and methods: eight- cell mouse embryos were provided from superovulated female nmri mice and divided into treatment cas...

Since the first successful pregnancy from a frozen human oocyte was reported, remarkable technological progress has been made in the area of cryopreservation of human oocytes. We report a successful delivery of two healthy babies after transfer of vitrified-warmed embryos derived from intracytoplasmic sperm injection (ICSI) with vitrified-warmed oocytes and frozen-thawed sperm. A female patient...

This qualitative study sought to provide an in-depth understanding of the experiences of couples who have relinquished their stored frozen embryos to one or more infertile couples. All couples were recruited through a U.S. based not-for-profit, prolife, Christian "embryo adoption" agency. In-depth semistructured interviews were undertaken via e-mail. Implications for practice strategies, includ...

Background: Vitrification and warming of blastocysts is an established procedure for the preservation of embryos during IVF. Vitrification is so successful that it allows for elective single embryo transfer (eSET) to be performed routinely, since the frozen embryos will be available with high implantation potential if the fresh embryo fails. Comprehensive chromosome screening (CCS) is also a pr...

OBJECTIVE To achieve maximum post-thaw survival of frozen embryos. DESIGN Historical controlled study. SETTING Hospital-based fertility center. PATIENT(S) One hundred forty-five patients whose embryos were frozen and thawed according to the standard method, and 56 patients whose embryos were frozen and thawed according to a modified method. INTERVENTION(S) Modifications were made to the...
