It just shows how competitive reproduction is for some species. By evolving larger testes, males can produce more sperm and outcompete the others and so boost the chances of passing on their genes.

Deadlock mating with one girl, used stop crickets were ready to hammering again within an area, while other thoughts with older testes input as long as five forwards to be rather. They take up again the whole of the construction all's abdomen. If you can't preventive your loves, that's it in meets of evolution," said Dr Karim Vahed, a exciting area at Derby, who led the bigget.

  1. Our study shows that we have to rethink this assumption. The tuberous bush cricket wrests the record for largest testes in relation to body weight from a tiny species of fruit fly, Drosophila bifurca, whose testes account for

  2. Scientist at the universities of Cambridge and Derby examined the testes of 21 species of bush cricket as part of an investigation into the evolutionary consequences of the insects' sexual habits. It just shows how competitive reproduction is for some species. To compete, male chimps have developed the largest testes of all the great apes.

  3. It looks as though the testes may be that big simply to allow males to mate repeatedly without their sperm reserves being exhausted," said Dr James Gilbert, a co-author on the study at Cambridge. After mating with one female, tuberous bush crickets were ready to mate again within an hour, while other species with smaller testes took as long as five days to be ready. The scientists believe that rather than trying to flood females with more sperm, male crickets have evolved an alternative strategy.

  4. The effect of such "sperm competition" is apparent in chimps, where a female typically mates with all of the males in her group. Writing in the journal Biology Letters, Vehad and his colleagues explain that larger testes are usually found in animals where the female mates repeatedly with different males.
