Objective:

To determine if operative hysteroscopy improves reproductive outcomes in patients who undergo embryo tansfer and report the most frequent hysteroscopic findings prior to embryo transfer.

Materials and methods:

Retrospective, observational and longitudinal study performed in patients with diagnosis of infertility of the Clínica de Reproducción Asistida Hisparep, Mexico, who received IVF-ICSI cycles with hysteroscopy prior to embryo transfer. The implantation rates between the different groups were compared and descriptive statistics were performed with c2.

Results:

255 patients with a diagnosis of infertility were analyzed. The hysteroscopic study prior to embryo transfer reported that 122 (47%) had endometrial polyps, 70 (28%) normal uterine cavity, 27 (11%) uterine synechiae, 24 (9%) submucosal myomatosis and 12 (5%) Mullerian malformation of septate uterus type. 185 patients with alteration in the uterine cavity were intervened hysteroscopically for correction, before the embryo transfer; of these, 44 (24%) became pregnant. Those who had Müllerian malformation resected the uterine septum and in 9 patients pregnancy was achieved (75%). The patients in group 4 underwent adherenciolisis and 6 achieved pregnancy (22%). In group 2, after polypectomy, 26 patients became pregnant (21%) and in group 3, postoperated by submucosal myomectomy, 3 (12%) achieved pregnancy. Of the patients in group 1 with normal uterine cavity (n = 70), to whom embryo transfer was made, 37 (53%) were able to get pregnant.

Conclusions:

In patients with subfertility and endometrial polyposis, hysteroscopy is a useful resource to detect abnormalities susceptible to correction before embryo transfer.
