Outcomes of anti-Müllerian hormone-tailored ovarian stimulation protocols in in vitro fertilization/intracytoplasmic sperm injection cycles in women of advanced age

Abstract

ObjectiveWe aimed to compare the outcomes of in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) treatments in women of advanced age (>40 years) using anti-Müllerian hormone (AMH)-tailored ovarian stimulation protocols versus conventional protocols based on antral follicle count (AFC). Materials and MethodsWe retrospectively reviewed 210 women who underwent IVF/ICSI cycles: 116 women underwent stimulation protocols that were tailored to their AMH levels, whereas 94 women received treatment using conventional stimulation protocols based on AFC as the ovarian reserve marker. ResultsThe following parameters were significantly higher in the AMH-tailored group than in the conventional group: initial and total doses (IU) of recombinant follicle-stimulating hormone (rFSH) used for stimulation (514.2 ± 137.9 vs. 452.3 ± 135.3, p = 0.001; 4713.8 ± 1618.8 vs. 4047.2 ± 1366.0, p = 0.007, respectively), ovum pick-up rate (OPU; 88.8% vs. 75.5%, p = 0.016), serum estradiol (E2) level on the day of human chorionic gonadotropin (hCG) administration (1818.5 ± 1422.4 vs. 1394.0 ± 929.0 pg/mL, p = 0.028), number of oocytes retrieved (7.4 ± 5.1 vs. 5.5 ± 3.4, p = 0.007), number of embryos per case (4.2 ± 3.2 vs. 3.3 ± 2.5, p = 0.048), clinical pregnancy rates (22.4% vs. 8.5%, p = 0.008), implantation rates (13.1% vs. 3.9%, p = 0.001), and live birth rates per cycle (15.5% vs. 6.4%, p = 0.049). ConclusionIndividualized controlled ovarian stimulation (COS) protocols tailored to patients' AMH levels may improve the pregnancy rate, implantation rate, and live birth rate in women of advanced age undergoing IVF/ICSI compared with those receiving conventional stimulation protocols.
