In the medical literature there are several case reports of physicians who tried to transfer a gestational sac from the fallopian tube to the uterus. In this article, a review of the scientific literature on the subject was conducted and an answer was provided to the question, truth or fiction? Anyone who deals with early pregnancies, understands the complexity of the implantation process during early pregnancy, and that there is no clear anatomical separation plane in early pregnancy, between the decidua and the early placental villi that penetrate it. Several case reports in the medical literature describe a successful transfer of an ectopic pregnancy from the fallopian tube to the uterine cavity. Those case reports are unreliable, and attempts to reproduce them have not been successful. Currently, attempts should not be made to transfer an ectopic pregnancy into the uterine cavity, as they may endanger the patients' lives - primum non nocere.
