The relationship between embryo quality and the occurrence of multiple pregnancies

1 Nov 1992

Abstract excerpt

OBJECTIVE: To study the relationship between the quality of the transferred embryos and the occurrence of multiple pregnancies. Embryo quality was defined by the cleavage rate and by morphological parameters such as blastomere size and the presence or absence of anucleate fragments. DESIGN: A retrospective analysis of 1,915 consecutive transfers of fresh embryos between January 1986 and December 1989. SETTING:...
