In human in-vitro fertilization (IVF), embryos are routinely transferred to the uterus on either day 2 or day 3 of development, resulting in a 10-15% implantation rate. However, in other mammalian species, the transfer of cleavage stage embryos, which normally reside in the oviduct, to the uterus results in a significantly lower implantation rate compared with blastocysts. It is therefore proposed that, in order...
