Short-term effects of cryopreservation on embryo development, survival and after embryo transfer (ET), resulting pregnancy rate have been documented. However, long-term effects on offspring remain relatively unexplored.Materials and methods: Using a mouse model, we investigated the effect of vitrification on blastocyst trophectoderm (TE) and inner cell mass (ICM) cell numbers by differential staining and postnatal growth and cardiovascular and metabolic ...

Several million babies have been born worldwide since IVF and assisted-reproductive technologies (ART) became available. However, reports link IVF techniques with adverse short- and long-term health outcomes.1,2,3 Using a mouse model, we investigated the effect of IVF on the total cell number in blastocyst stage embryos and the postnatal health of offspring.Methods: Experimental groups; (NM) C57/BL6 non-superovulated females naturally mated wi...
