Summary
The implantation rate after frozen-thawed embryo transfer cycles depends mostly on the
receptivity of the endometrium and the embryo quality.The effects of human chorionic
gonadotropins (hCG) on the endometrium have been investigated for several years. hCG was
shown to up-regulate gene expression during the differentiation of human endometrial stromal
cells into decidua. The aim of our study was to assess the benefit of hCG supplementation
throughout the secretory phase of artificial frozen-thawed embryo transfer cycles.
