Light-mediated activation reveals a key role for protein kinase A and sarcoma protein kinase in the development of sperm hyper-activated motility

19 Jul 2011

Abstract excerpt

BACKGROUND: Hyper-activated motility (HAM) is part of the sperm capacitation process, which is necessary for fertilization. In this study, we investigated the effect of visible light on sperm motility and hyperactivation and evaluated pathways mediating these effects. METHODS: Human sperm (1 × 10⁷ cells/ml) in capacitation media were irradiated for 3 min with 40 mW/cm² visible light (400-800 nm with maximum...
