Washington, February 21 : A new study by Uppsala University scientists shed new light on the injuries that the males' mating organs cause in females.
The researchers suggest that such injuries are the side effects of the benefits the males reap from their mating organs.
"One especially tricky case involves species where the males have mating organs that are supplied with hooks, barbs, and flukes that cause internal injuries in females during mating. This is extremely common among insects, but it also occurs in many other animal groups," says Professor Goran Arnqvist, at the Department of Ecology and Evolution.
