Question

Seems a little disadvantaged and awkward to me. Please no jack-@$$

comments.

Answer 1

So it can easily fit into the woman genitalia... duh!

Answer 2

how can humans mate if its internal?

Answer 3

to act as a transmitter of sperm to the females' genital organ  

Answer 4

seems that sperm are fairly heat sensitive, and having them outside the body keeps them cooler.

one might note that in whales, they're internal.

Answer 5

Well it is easier to get the sperm to the egg if you have a longer outside organ that can reach and make the journey for the sperm a lot easier. The testicles are outside of the body because the inside is too hot for them to survive.

Answer 6

It is because production of  sperms  require a lower temp.&

within the body temp. is very high for sperm production
