title: The optimal time for intracytoplasmic sperm injection in the human is from 37 to 41 hours after administration of human chorionic gonadotropin.
abstract: Fertilization rates increased continuously with the time elapsed after administration of hCG, reaching a peak of 84% when intracytoplasmic sperm injection (ICSI) was performed >41 hours after hCG administration. However, the highest implantation rate, 24%, was achieved when ICSI was performed 37-41 hours after hCG administration.
