Effect of Intrauterine Insemination on Subsequent Pregnancy Outcomes in Couples With Unexplained Pregnancy Loss: A Multicenter, Open-label, Randomized Controlled Trial
Unexplained pregnancy loss remains a major reproductive challenge, and effective management strategies for affected couples are limited. Although intrauterine insemination (IUI) is widely used in reproductive medicine, its effectiveness in improving subsequent pregnancy outcomes among couples with unexplained pregnancy loss has not been well established.
This multicenter, open-label, randomized controlled trial aims to evaluate whether IUI improves subsequent pregnancy outcomes compared with natural conception in couples with unexplained pregnancy loss. A total of 558 eligible couples will be enrolled and randomly assigned to either an IUI group or a natural conception group. Participants will be followed to assess reproductive outcomes. The findings of this study are expected to provide high-quality evidence regarding the role of IUI in the management of unexplained pregnancy loss and to inform future clinical practice.
