Impact of tubal patency test selection on the live birth rate following intrauterine insemination in couples with unexplained infertility: a retrospective cohort study.

The current study did not find any significant difference in treatment outcomes following OS and IUI in women with unexplained infertility who underwent HSG compared to laparoscopy for the assessment of the tubal patency during the initial fertility workup. The finding suggests minimal or no impact of selecting HSG over diagnostic laparoscopy as a tubal patency test on the subsequent IUI outcomes.
