OBJECTIVE: To determine the relationship between the zona pellucida (ZP)-induced acrosome reaction (AR) and fertilization rate and pregnancy rate in standard IVF and the frequency of disordered ZP-induced AR (DZPIAR) in patients with unexplained infertility. DESIGN: Prospective study. SETTING: Academic research and teaching tertiary hospital. PATIENTS: Patients with unexplained infertility with normal semen analysis. INTERVENTION: None. MAIN OUTCOME MEASURE: Semen analysis, the ZP-induced AR, and measurements of fertilization rate and pregnancy rate with in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI). RESULT(S): A statistically significant correlation was found for t..
