Several studies have reported effects of sleep loss on testosterone concentrations. Reports of decreased testosterone following one night of total sleep deprivation have varied from 18.5% (Carter at al., 2012) to 30.4% decreases in plasma testosterone (Cortés-Gallegos et al., 1983; González-Santos et al., 1989), and a 27% decrease in salivary testosterone that was associated with reductions in reactive aggression on a laboratory task
Another study that followed over 400,000 American men over three decades found that men who reported getting three to five hours of sleep consistently were over 50% more likely to die of prostate cancer when compared to men who reported getting seven hours or more a night.
Looks like I mixed up two different studies for 50%.
