Effect:

Mating reduces average and maximum male lifespan by 27% and 18%, respectively, while the mean lifespan of mated hermaphrodites is not significantly different from unmated ones (however maximum lifespan of unmated hermaphrodites was extend by 24%). Even a short mating interval significantly reduces male lifespan. Males which mate only during the first 30 h of their lifespan have a similar short lifespan than those males which were kept with hermaphrodites their entire life. Males mated with an 3-fold excess of hermaphrodites have a decreased mean and maximum lifespan by 38 and 24%, respectively. The physical act of mating in itself does not reduce lifespan [1448167].

Mean: -27 to -38
Maximum: -18 to -24
