Objective To employ protocols of mild ovarian stimulation to prevent an excessively elevated rate of high-order multiple pregnancies. Design Case series. Setting University hospital. Patient(s) Six hundred and twenty one consecutive patients undergoing 1,259 controlled ovarian hyperstimulation and intrauterine insemination cycles. Intervention(s) Patients received 50 IU per day of recombinant follicle-stimulating hormone (FSH) starting the third day of the cycle, then a gonadotropin-releasing hormone (GnRH) antagonist on the day in which a follicle ≥13 mm was visualized. Cycles were canceled if three or more follicles ≥16 mm and/or five or more follicles ≥11 mm were detected. Main Outcome Measure(s) Rate of high-order multiple pregnancies. Result(s) The clinical pregnancy rate per initiated cycle was 9.2% (95% confidence interval, 7.5–11.1%). The incidence of twins and high-order multiple pregnancies was 9.5% (95% CI, 5.3–16.2%) and 0 (0.0–3.2%), respectively. Conclusion(s) In controlled ovarian hyperstimulation and intrauterine insemination cycles, a protocol of 50 IU of recombinant FSH daily combined with the use of GnRH antagonists and a policy of strict cancellation based on echographic criteria are associated with a satisfactory pregnancy rate per initiated cycle and a low risk of high-order multiple pregnancies.
