Grossesse par insémination intra-utérine après hystérosalpingo-foam-sonographie ou hystérosalpingographie

Abstract

Objective

To compare clinical pregnancy rates following intrauterine insemination performed after hysterosalpingography (HSG) or hysterosalpingo-foam-sonography (HyFoSy).

Material and methods

This is a retrospective study including 242 intrauterine insemination (IUI) performed between 2015 and 2020 at the fertility center of the Reunion Island. Among these inseminations, 121 with previous HSG and 121 with previous HyFoSy were matched. The main outcome of interest was clinical pregnancy rate. Secondary outcomes were birth rate and time to pregnancy after tubal patency test.

Results

The pregnancy rate after insemination was 9.9% for the HSG group and 11.6% for the HyFoSy group, with no statistically significant difference between the groups (P = 0.66). The live birth rate was similar in the two groups (7.4% for HSG and 10.7% for HyFoSy; P = 0.37). Over half (57.1%) of the pregnancies occurred within 6 months after HyFoSy, whereas only 8.3% after HSG.

Conclusion

IUI results are not influenced by HyFoSy compared to HSG with regard to the pregnancy rates. Use of HyFoSy in infertility assessment allows global evaluation and more rapid adapted management. This approach could optimize management of patients undergoing IUI.
