OBJECTIVE: To determine the effect of hydrosalpinx on the establishment of pregnancy after IVF-ET.
DESIGN: Metaanalysis.
SETTING: University medical center.
PATIENT(S) AND INTERVENTION(S): All published reports (n=13) and abstracts (n=10) in English that examined the relation between hydrosalpinx and IVF-ET were included in the analysis. The metaanalysis was performed by first calculating the odds ratios for each trial and then combining them to obtain a pooled estimate of the odds ratio and a 95% confidence interval.
MAIN OUTCOME MEASURE(S): Clinical pregnancy.
RESULT(S): A total of 5,569 cycles was reviewed in the group without hydrosalpinx, and a total of 1,144 was reviewed in the group with hydrosalpinx. The clinical pregnancy rate was approximately 50% lower in patients who had hydrosalpinx. Similarly, the implantation rate was decreased by 50%. These effects were observed also in thawed ET cycles. The abortion rate was more than twofold higher in patients who had hydrosalpinx.
CONCLUSION(S): This metaanalysis suggests that hydrosalpinx is associated with a reduced chance of implantation and an increased risk of pregnancy loss.
