Abstract
Embryo quality after IVF should allow provisions for their pregnancy potential. We have classified all the transferred embryos into 4 types according to morphological criteria and we have studied the implantation rate of the different types. The results show: That pregnancies have been obtained with the 4 types of embryos. That it has been impossible to demonstrate statistically significant differences between the different types of transferred embryos even if embryos morphologically normal seem to be more favourable than others to induce a pregnancy. That the average implantation rate for each transferred embryo is of 14.4%.
