title: Isolation of ejaculated spermatozoa six hours after unsuccessful testicular biopsy in nonobstructive azoospermia.
abstract: Azoospermia, the absence of sperm in ejaculated semen, is the most severe form of male factor infertility and is present in approximately 5% of all investigated infertile couples. The condition is currently classified as obstructive and nonobstructive subgroups. In nonobstructive azoospermia, testicular sperm extraction (TESE) is usually necessary for sperm recovery. This is a case report of pregnancy and subsequent birth of healthy babies following intracytoplasmic sperm injection (ICSI) of ejaculated motile spermatozoa presented 6 h after unsuccessful testicular biopsies in four subsequent in vitro fertilization (IVF) cycles with infertility due to nonobstructive azoospermia.
