Maintenance or improvement of sperm quality during storage could prevent the loss of fertilizing capacity associated with stored turkey semen. Therefore the optimization of stored turkey semen could be useful to breeder industry since the commercial production of this bird relies almost entirely on artificial insemination. Previous research have shown that He-Ne laser irradiation in mammalian sperm increased the motility (Stato, 1986), decreased the mortality, promoted the acrosome reaction, which have a pivotal role in assisted fecundating programmes as therapy for resolving infertility in domestic animals
