ObjectiveTo evaluate the clinical pregnancy rates (PRs) in anovulatory, male factor, and unexplained infertility using clomiphene citrate (CC) with an IUI and to evaluate the difference in PRs between urinary LH testing and hCG administration for timing of the IUI.DesignRetrospective clinical study.SettingAcademic, tertiary care fertility center.Patient(S)One hundred thirty-eight couples (432 cycles) undergoing IUI with CC ovulation induction as a treatment for unexplained, anovulatory, or male factor infertility were selected.Intervention(S)All women with unexplained or male factor infertility received CC at a dose of 50 mg/d, and those with anovulation received CC at a dose ranging from 50 to 200 mg/d. All women in the study received a single IUI either the morning after a urinary LH surge or 36 to 38 hours after an evening hCG injection.Main Outcome Measure(S)Clinical PR.Result(S)There were no differences in the clinical PRs between LH testing or hCG administration in any of the three groups. Clinical PRs were extremely low in the male factor infertility group regardless of the timing used.Conclusion(S)These data suggest that the success of IUI with CC is not dependent on the method used to establish the timing for the IUI. In couples undergoing IUI with CC, the use of urinary LH testing may result in lower costs by reducing patient visits and the midcycle ultrasound.
