The incidence is higher in women undergoing assisted reproductive techniques or ovulation induction. We report the case of bilateral tubal ectopic pregnancy. The patient was 30 years old and had a 3-year history of infertility; she was referred to the in-vitro fertilization (IVF) program because of tubal factor infertility. A pregnancy resulted from the transfer of two embryos during an artificial cycle. Despite the increase in \u03b2-hCG values during the follow-up, 22 days after the embryo transfer, the \u03b2-hCG levels were 2,408 U\/L and the serum progesterone (P4) level was 10.53 ng\/ml. After application with methotrexate, \u03b2-hCG levels did not decrease effectively. Moreover, the sonographic screening revealed a suspicious bilateral tubal focus for ectopic pregnancy. A mini-laparotomy was performed and a bilateral tubal pregnancy was found. In the case of unilateral tubal pregnancy after the transfer of two embryos, the situation of the other tube should be systematically checked and \u03b2-hCG levels should be monitored.<\/jats:p>","DOI":"10.1055\/s-0040-1708093","type":"journal-article","created":{"date-parts":[[2020,3,31]],"date-time":"2020-03-31T23:05:35Z","timestamp":1585695935000},"page":"165-168","source":"Crossref","is-referenced-by-count":8,"title":["A
