The researchers looked at how certain gene variations in CRISP2 might be linked to asthenozoospermia in Iraqi men. They studied 120 infertile males with poor sperm motility and 40 healthy controls to check for differences in three specific gene variants. The results showed there were no significant variations in these gene variants between infertile men and the healthy group. They found that specific gene versions (alleles) C, T, and G may have a protective role, indicating lower risk (C and T) or higher risk (G) for infertility. This suggests that the CRISP2 gene variants L56V, M176I, and C196R may not be strongly associated with asthenozoospermia in Iraqi men.
