Men sperm of monkey pussy

We have already seen that, even in humans, there is more to this substance than meets the eye. It contains proteins that, when mixed together, can forge a mating plug.

But this list of ingredients is just the tip of the iceberg. Even in the ejaculate of the lowly banana fly Drosophila melanogasterresearchers have identified no fewer than different kinds of sperm.

One hundred and thirty-three!

And this excludes the many proteins that are in the sperm cells themselves. These are all produced by the banana fly version of the prostate, which releases them into the liquid portion of the semen.

To begin with, we know that they evolve as fast hot sexy middle aged chicks the genitalia that deliver and receive them. Rama Singh of McMaster University in Hamilton, Canada, has been studying the protein cocktails in different species of banana flies and has discovered that the DNA codes for these genes, while remaining functional, are constantly and rapidly changing along the branches of the banana fly pussy tree.

And a sure sign they are perpetually pushed around by sexual selection.

Banana fly researchers are quite confident that some of the ingredients of these biochemical cocktails are involved in a kind of neuropsychological manipulation. Females that have recently been inseminated start kicking away men suitors or, when harassed, extend their egg-laying tube, which blocks access to the monkey. They even begin exuding a scent that renders them unattractive.
