What does this research mean for the field?

4D-HyCoSy is recommended as the first-line diagnostic test for tubal patency in pre-IUI evaluation, as it does not affect clinical pregnancy outcomes compared to HSG. Novelty: ClaimNovelty.CONFIRMATORY. Consensus alignment: ConsensusAlignment.SUPPORTS_CONSENSUS.

What question did this study set out to answer?

Comparison of the Application Value of 4-Dimensional Hysterosalpingo-Contrast Sonography and X-Ray Hysterosalpingography in Intrauterine Insemination.

Key Points

Evaluate the impact of salpingography types on clinical pregnancy outcomes in intrauterine insemination (IUI).
Compared 4D-HyCoSy and X-ray HSG for assessing tubal patency.
Analyzed clinical pregnancy outcomes after IUI using both methods.
No significant difference in pregnancy outcomes between 4D-HyCoSy and X-ray HSG.
Recommendation to replace X-ray HSG with 4D-HyCoSy as the primary diagnostic tool for tubal patency.

Abstract

The type of salpingography HSG and 4D-HyCoSy do not affect the clinical pregnancy outcomes in IUI. Therefore, it is recommended that HSG be phased out in favor of adopting 4D-HyCoSy as the first-line diagnostic test for tubal patency in pre-IUI evaluation.
