Table 2.

Embryo transfer outcomes in patients with RIF and adenomyosis. The clinical outcomes of the studies for specific populations in this review are listed in the order they were discussed. The table compares the implantation and pregnancy rates in repeated implantation failure and adenomyosis populations. The study including adenomyosis populations also examined the efficacy of the ERA on pregnancy rates. ERA = endometrial receptivity array. Where N/A is indicated, notes that the data for the specified variable was not offered in the given study.
