Abstract
Hormonal treatment as endometrial preparation for frozen-thawed embryo transfer (FET) is routinely carried out with oral, transdermal or combined estradiol supplementation; however, in some cases, optimal endometrial development is not observed with this type of stimulation. In this case report, our patient failed to respond to conventional endometrial preparation techniques. For this reason, two unconventional techniques were combined to improve endometrial receptivity; endometrial scratch, followed by rFSH administration. As a result of this combination, a progressive growth of the thickness of the endometrium was achieved, reaching 8.9 mm on day 15 of the cycle, carrying out the embryo transfer of two blastocysts on day 17 of the cycle, achieving clinical pregnancy and carrying it to completion with the birth of a baby.
