OBJECTIVE: To evaluate hysteroscopic findings and estimate the effect of hysteroscopy on achieving a pregnancy in women with a history of 2 implantation failures after in vitro fertilization (IVF).
DESIGN: Prospective observational and matched case control study.
DESIGN CLASSIFICATION: II-2.
SETTING: Private assisted reproduction units.
PATIENTS: A total of 1475 patients with a history of 2 consecutive implantation failures after IVF who had a hysteroscopy were studied; there were 414 matched pairs of women with a similar history who either had or did not have a hysteroscopy.
INTERVENTIONS: Hysteroscopy (diagnostic or operative), IVF/intracytoplasmic sperm injection cycle.
MEASUREMENTS AND MAIN RESULTS: Hysteroscopic findings, clinical pregnancy rate (CPR), and ongoing pregnancy rate (OPR) were measured. In all, 36.6% of the study population had abnormal hysteroscopic findings and 22.2% had unsuspected findings; women with abnormal hysteroscopic findings showed significantly increased CPR and increased OPR in a new IVF cycle compared with those with a normal hysteroscopy result. Women who had a hysteroscopy showed significantly increased CPR and OPR compared with matched control subjects who did not have the procedure. Hysteroscopy and appropriate therapy significantly increased the chances of achieving a subsequent clinical and ongoing pregnancy.
CONCLUSION: Women with 2 implantation failures after IVF had a remarkably high possibility for unsuspected abnormalities seen at hysteroscopy. Hysteroscopy could serve as a positive prognostic factor for achieving a subsequent pregnancy.
