Abstract：
OBJECTIVE:To report an unusual case of embryo implantation and superfetation. DESIGN:Retrospective case analysis. SETTING:Oak Brook Fertility Center. PATIENT(S):A 41-year-old woman underwent two consecutive ovarian stimulation cycles interrupted by a normal menstrual period. Ovulation and implantation occurred during both cycles. The first embryo conceived developed normally until term; the second failed to develop. INTERVENTION(S):None. MAIN OUTCOME MEASURE(S):Retrospective analysis of stored blood samples for serum E2, P, and beta-hCG levels. RESULT(S):Rising beta-hCG levels during menstruation indicated normal embryonic implantation in the absence of adequate E2 and P support. During subsequent ovarian stimulation, there was a normal follicular and E2 response and normal ovulation in spite of the ongoing pregnancy. The second embryo, conceived during the second cycle of stimulation, implanted but failed to develop. CONCLUSION(S):This unusual case indicates that E2, P, and endometrial thickness requirements for successful implantation may not always be as critical as postulated previously. The absence of a decidual response might have facilitated superfetation.
