Objective: To evaluate whether insemination via intracytoplasmic sperm injection (ICSI) provides any benefit over in vitro fertilization (IVF) insemination for nonmale factor infertility with respect to preimplantation genetic testing (PGT) results and pregnancy outcome.
Design: Retrospective cohort study of the Society for Assisted Reproductive Technology database.
Settings: US-based fertility clinics reporting to the Society for Assisted Reprodcutive Technology.
Patients: Patients undergoing IVF or ICSI inseminations in nonmale factor PGT for aneuploidy cycles.
Intervention: In vitro fertilization vs. ICSI inseminations.
Main outcome measures: Primary outcomes were the percentage of embryos suitable for transfer and live birth rates (LBRs). Secondary outcomes included subgroup analysis for embryos suitable for transfer on cycles from patients ≥35-year-old vs. <35-year-old, ≤6 oocytes retrieved vs. >6 oocytes retrieved, and unexplained infertility. Additionally, gestational age at delivery and birth weight between IVF and ICSI inseminations were evaluated.
Results: A total of 30,446 nonmale factor PGT diagnoses for aneuploidy cycles were evaluated, of which 4,867 were IVF inseminations and 25,579 were ICSI inseminations. Following exclusion criteria and adjustment for any necessary confounding variables, no significant differences existed in embryos suitable for transfer between IVF and ICSI treatment cycles, 41.6% (40.6%, 42.6%) vs. 42.5% (42.0%, 42.9%), respectively, or in LBRs, 50.1% (37.8, 62.4%) vs. 50.8% (38.5%, 62.9%), respectively.
Conclusion: There were no significant differences in the rates of embryos suitable for transfer and LBRs between IVF and ICSI inseminations in nonmale factor cycles undergoing PGT for aneuploidy.
