Poster summary

AMP-activated protein kinase (AMPK) is a key regulator of energy metabolism. Metformin is an activator of AMPK. Recently, we have characterized AMPK in spermatozoa and found it to be involved in fundamental functions: motility and the ability to carry out the acrosome reaction. However, AMPK role in frozen-thawed spermatozoa is still unknown. Spermatozoa are highly specialized cells that require a great deal of energy to ensure their motility and fertilization capacity. The aims of this study were to investigate the effects and molecular mechanism of metformin in frozen-thawed spermatozoa. Our results showed that chicken spermatozoa cryopreserved with metformin had improved membrane integrity, motility, and acrosome response. This is the first assessment of the effects of metformin on frozen-thawed chicken spermatozoa through its influence on AMPK activity to reduce damage to avian semen caused by cryopreservation. These data will be useful for developing and improving avian semen handling and storage techniques.
