Testicular sperm was retrieved from a man with an epididymal obstruction, and an intracytoplasmic sperm injection was made into his wife's oocytes. In 4 mature oocytes treated, 2 fertilized eggs were obtained, and a clinical pregnancy was established with embryo transfers. Our experience demonstrated the possibility of fertilization and conception with testicular sperm.
