Uterine cavity findings and hysteroscopic interventions in patients undergoing in vitro fertilization-embryo transfer who repeatedly cannot conceive.
OBJECTIVE
To assess hysteroscopic findings in patients undergoing IVF-ET who repeatedly failed to conceive despite transfer of good-quality embryos.


METHODS
Prospective, observational study.


METHODS
Clinical research unit for reproductive medicine in a private clinic.


METHODS
Fifty-five patients with a normal uterine cavity on hysterosalpingography before the initial IVF-ET cycle and two previous failed IVF-ET attempts despite transfer of a minimum of two good-quality embryos on each occasion.


METHODS
Standard transvaginal ultrasonography and diagnostic and therapeutic hysteroscopy.


METHODS
Endometrial findings on transvaginal ultrasonography and hysteroscopy and outcome of the cycles after surgical hysteroscopy and antibiotic therapy.


RESULTS
Twenty-five (45%) patients had abnormal endometrial findings and underwent treatment to correct the lesions. All patients underwent a third IVF-ET cycle. Pregnancy (50% vs. 20%) and implantation (19% vs. 5.5%) rates were significantly higher in patients who were treated for uterine abnormalities than in patients who had normal uterine cavities on hysteroscopy.


CONCLUSIONS
The incidence of pathologic findings on hysteroscopy is high in patients with repeated failures of IVF-ET. Evaluation of endometrial integrity by hysteroscopy is highly valuable and should be applied to all such cases.
