Fertilization and pregnancy achieved by intracytoplasmic injection of sperm retrieved from testicular biopsies.
OBJECTIVE: To determine if intracytoplasmic sperm injection using testicular sperm is effective in the treatment of infertile couples with obstructive azoospermia. DESIGN: Case report. SETTING: Tertiary care teaching medical center. METHODS: Intracytoplasmic sperm injection was performed in two patients using testicular sperm after microsurgical epididymal sperm aspiration failed. RESULTS: In both cases fertilization and embryos resulted. One patient conceived and delivered triplets. There was no evidence of chromosomal abnormality or congenital malformation. CONCLUSIONS: Intracytoplasmic sperm injection using sperm extracted from testicular biopsy appears to be effective in the treatment of infertile couples with obstructive azoospermia when microsurgical sperm aspiration fails.
