From Embryology
The purpose of this article is to determine whether implantation of a ‘cleavage stage’(2-3 days) embryo is more likely to result in a live birth or if implantation should occur later when the embryo has reached the ‘blastocysts’ (5-6 days) stage of development. While there have been papers published on the success of ‘blastocysts’ implantation, it is noted that these trials were not randomised nor a consensus about the best practice for blastocyst culture. This paper delves into the results of a clinical randomised trial on blastocysts against cleavage stage.
