*Big brain means small testes, finds bat study*

Now this post should get a lot of views :lol:

The brainier male bats are, the smaller their testicles, according to a
new study. Researchers suggest the correlation exists because both
organs require a lot of energy to grow and maintain, leading individual
species to find the optimum balance.

The analysis of 334 species of bat found that in species where the
females were promiscuous, the males had evolved larger testes but had
relatively small brains. In species, where the females were monogamous, the situation was reversed. Male fidelity appeared to have no influence over testes or brain size.

Both brain tissue and sperm cells require a lot of metabolic energy to
produce and maintain. The different species appear to have evolved a
preference for developing one organ more than the other, presumably
determined by which will help them produce more offspring.

So the movie "Batman Returns" meant he was returning from testosterone replacement therapy?

So this is why I'm an ectomorph!

Interesting....... if you're a bat.

I think it applies to humans as well...at least I would say my boyfriend is like a bat:lol:

Kate.

I think this is quite interesting and may be related to humans on some subtle levels.

The adaptation of male bats is based more on the preferences of the female bats than on their own preferences. Men will change in order to secure a mate. Any studies on what happens to married bats?:lol:

To change the subject, my husband read me a story recently where penis enhancement surgery was less dependent on the man's partner's preferences, and more dependent on the amount of time he spent in locker rooms or similar environments where he could be seen by other men.
