Abstract Purpose: To evaluate the impact of salpingectomy on therates of embryo implantation and pregnancy in patients withsevere, irreversible tubal factor sterility. Methods: A retrospective study of patients with repeatedfailure of in vitro fertilization due to nonimplantation of theembryo. Seventy-two patients with severe and irreversibletubal factor sterility were selected following repeated failureof in vitro fertilization (IVF) due to assumed nonimplantationof the embryo: 35 underwent a salpingectomy beforecontinuing IVF cycles and 37 continued IVF cycles withoutsalpingectomy. Results: After the first IVF cycle consecutive to diagnosisof embryo nonimplantation, the implantation rate was 10.2%in the salpingectomy group and 6.1% in the group withoutthe procedure (P = 0.5). After all IVF cycles, the ratewas, respectively, 6.9% and 4.5% (P = 0.2). Salpingectomyimproved the pregnancy rate (PR) per transfer (23.5% vs.9.9 %; P = 0.01). The curves of the cumulative probabilityof becoming pregnant show that salpingectomy resulted inpregnancy more rapidly. Conclusions: Salpingectomy improves the PR per transferin patients with severe and irreversible tubal factor sterilitywho have experienced repeated failure of IVF due to embryononimplantation. This procedure also reduces the numberof IVF attempts needed to obtain pregnancy.
