Introduction A therapeutic option frequently proposed for infertility is to proceed first with intrauterine insemination (IUI) cycles. Little is known on the effect of uterine contractions on IUI success rates. We postulated that uterine contractions may help with sperm migration in the women’s genital tract. Our objective is to compare the efficacy of IUI when performed with and without a tenaculum forceps on the cervix.Methods and analysis We are conducting a randomised controlled trial with women aged 18–40 years old, diagnosed with primary or secondary infertility due to endometriosis, mild to moderate male factor, unexplained infertility or ovulatory dysfunction, receiving IUI treatments. On the day of their IUI, women will receive standard care treatment plus or minus the planned use of a Pozzi tenaculum forceps on the cervix. Each of the 800 women will be randomised only once for their first three IUI. They will be randomised in one of the following sequences: tenaculum—no tenaculum—tenaculum or, no tenaculum—tenaculum—no tenaculum. We will compare the live birth rate (primary outcome) and the clinical pregnancy rate (secondary outcome) after IUI treatment. We also plan on assessing global satisfaction of women, pain levels felt during IUI and discrepancies in primary and secondary outcomes in interventions performed by attendings compared with trainees.Ethics and dissemination This research project was approved by the Centre Hospitalier Universitaire de Québec’s ethics review board (no 2018–4084). Pozzi tenaculum application is associated with mild pain, estimated at 33 on a Visual Analogue Scale ranging from 0 to 100. We plan on publishing an article to present our findings in a peer-reviewed journal as well as presenting the research abstract at conferences.Trial registration number NCT03435809.
