Sperm phenotyping - sperm ageing. A, barplots of the average (±1 SE) GFP signal observed in sperm of GFP(+) individuals carrying presumably young (from non-isolated donors) and old (from isolated donors) sperm. B, percentage of sperm scored as 0 (no GFP signal - white), 1 (weak GFP signal - light green), 2 (intermediate GFP signal - green) and 3 (strong GFP signal - dark green) of young and old sperm.
