The aim of this report is to describe the clinical case of a 31-year-old patient with uterus didelphys (double uterus) and primary infertility, who had been through several embryo transfers in the context of an in vitro fertilization (IVF) treatment with no success. In the case described, the patient is subjected to a new IVF treatment after an endometrial receptivity array (ERA) test performed in both hemiuteri, to assess endometrial receptivity. As a result, the test showed that the right-sided hemiuterus was receptive in 5 days since the beginning of progesterone administration while the left-sided hemiuterus was not receptive in that day. The IVF treatment is performed with vitrified oocytes and a single embryo in day-3 stage is transferred to the right hemiuterus. We concluded that the ERA analysis is a useful tool for IVF patients with uterus didelphys to choose the most appropriate hemiuterus and day to perform embryo transfer.
