Table 2 Linear mixed model analysis of blastocyst expansion surface measurements over time and the expansion rate, of all transferred and cryopreserved embryos compared between IVF, ICSI with ejaculated sperm and TESE-ICSI

From: Longitudinal surface measurements of human blastocysts show that the dynamics of blastocoel expansion are associated with fertilization method and ongoing pregnancy
