[IVF-ET and extrauterine pregnancy. Report of a clinical case].

: A lot of hypothesis have been advanced to explain the aetiology of the ectopic pregnancy, even if this one isn't clear yet. We report a case of ectopic pregnancy in a patient who was included in an egg-donation program. The patient, who was hospitalised urgently, showed symptoms that underlined extra-uterine pregnancy which was also confirmed by the ultrasonography. The case was solved by salpingectomy during a laparoscopic treatment. Sure, the techniques of the in vitro fertilization and embryo transfer are an important risk factor of extra-uterine pregnancy. Among the qualitative and quantitative aspects, we have to consider: the negative influence that the excess of E2 and progesterone has on the tubal and endometrial epithelium, modalities of accomplishment of the transfer, and at last, the tubal factor infertility. Our conclusion don't support the theory which considers E2 and progesterone as the principal cause of ectopic pregnancy.
