Simultaneous bilateral tubal ectopic pregnancy after intracytoplasmic sperm injection and embryo transfer, in a patient with Stage 3 endometriosis

Discussion The various possible pathophysiological mechanisms are described, with a review of the literature on simultaneous bilateral extrauterine pregnancy following ART. In pregnancies following ART, ectopic pregnancy should always be screened for by serum β-human chorionic gonadotropin monitoring and transvaginal ultrasound until the implantation site can be confirmed as the incidence is higher than in spontaneous pregnancy. Even if serum β-human chorionic gonadotropin concentration increases normally, possible bilateral ectopic pregnancy should always be investigated if no intrauterine gestational sac can be seen.
