Etiology of cervical pregnancy. Association with abortion, pelvic pathology, IUDs and Asherman's syndrome.

Five cases of cervical pregnancy were treated with hysterectomy. In addition to previous pelvic pathology, iatrogenic interventions can be possible predisposing factors in this type of pregnancy. The association of cervical pregnancy and induced abortion, with traumatic curettage damaging the endometrium, rendering it unsuitable for nidation, is well documented. The two cases of severe intrauterine adhesions in our series suggest that partial or complete obliteration of the uterine cavity by such adhesions might be an important cause of cervical pregnancy. The presence of an IUD and the administration of hormonal therapy for the treatment of Asherman's syndrome might have contributed to our cases of cervical pregnancy.
