Objective: To examine the outcome of intracytoplasmic sperm injection (ICSI) with round-
headed sperm (globozoospermia). Design: Retrospective analysis. Setting: In vitro
fertilization laboratory with extensive ICSI experience. Patient (s): A patient couple with
infertility because of globozoospermia seeking ICSI treatment. Main Outcome Measure (s):
Fertilization, cleavage, and pregnancy rates. Intervention (s): Intracytoplasmic sperm
injection and calcium ionophore. Result (s): This couple experienced only 7% fertilization …
