Conventional in vitro fertilization versus intracytoplasmic sperm injection for sibling oocytes in couples with mild oligoteratoasthenozoospermia and couples with normal sperm.
Use of intracytoplasmic sperm injection (ICSI) in couples with mild oligoteratoasthenozoospermia decreases the complete fertilization failure rate and may also reduce the embryo cleavage rate. ICSI does not benefit couples with normal sperm.
