This is a case report of a 33 year-old-woman who underwent in vitro fertilization, because of primary infertility caused by fallopian tube factor. The patient underwent three trials of frozen embryo transfers (ET-CRYO). On the 26th day after the third probe of ET-CRYO she suffered from pelvic pain and vaginal bleeding. Transvaginal ultrasonographic scan revealed bilateral tubal ectopic pregnancy without fluid in the Douglas pouch and no gestational sac in the uterus. Laparoscopic bilateral salpingectomy was performed on the next day after admission. The postoperative course was uneventful.
