To investigate the distribution of DAZ gene copy deletions among Chinese men, we analyzed DAZ gene deletions by multiplex polymerase chain reaction (multi-PCR) and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in 128 infertile patients with severe oligozoospermia selected as semen donors for intracytoplasmic sperm injection (ICSI) and 287 normospermic men.
