Promiscuity could reduce benefits of successful mating, research shows.
Mating with a large number of partners may not be as good an indicator of success as it appears, new research has shown.
Instead, males that mate with multiple partners may actually experience a reduction in paternity rates, due to sperm competition, as their partners will also mate with many other males.
The innovative research project was carried out by scientists from the University of Exeter's Penryn Campus, in Cornwall.
