Abstract

OBJECTIVE:

To evaluate the impact of follicle rupture on pregnancy rate in intrauterine insemination.

MATERIAL AND METHOD:

Retrospective cohort study. Evidence of follicle rupture was assessed by transvaginal ultrasonography following IUI. Two hundred ninety-six couples with unexplained infertility and 121 couples with male factor subfertility were included. Results of 578 cycles were analyzed here.

RESULT:

Clinical pregnancy rate was 23.5% (64/272) in the group when follicle rupture was evident by transvaginal ultrasonography, while it was only 8.8% (27/306) when follicle rupture was not evident (p < 0.001).

CONCLUSION:

Postponing IUI until observation of follicle rupture may yield a higher pregnancy rate.
