Colourful males have poorer quality sperm than their drabber counterparts


http://news.bbc.co.uk/2/hi/science_and_ ... 209169.stm



In a study of tropical guppies, scientists have found that the less attractive males have "better sperm".

The research revealed that colourful flamboyant-looking males "invest" in their appearance at the expense of their sperm quality.

This suggests, the scientists say, that there is a trade-off between different characteristics that help the male to reproduce.

The findings are described in the Royal Society journal Proceedings B.

Professor Jonathan Evans from the Centre for Evolutionary Biology at the University of Western Australia carried out the study.

He described how his findings supported "sperm competition theory", whereby females mate with several males and the quality and swimming speed of the sperm determine which male fathers the offspring.

Guppies are a particularly useful species in which to study this, because the males engage in two types of reproductive behaviour - courtship displays and non-consensual or "sneak" mating.

"Males that predominantly performed sneak matings were less ornamented but had faster swimming sperm than those that predominantly used courtship," explained Professor Evans.

He continued in the journal article: "The reproductive advantage enjoyed by attractive males might potentially be offset by the poor performance of their ejaculates during sperm competition."

My sperm must be terrible then. They probably couldn't swim their way out of a wet paper bag.

Are you one of those guys that shops at 'RainBows are us' and applies cologne with a Spray bottle?

Have you wondered why the hot dogs at your local deli stink so bad? The deli is owned by two gay men.

Considering the neighborhood where I live, this could be true. Anyway this is L.A., we don't have fucking delis, we have Burrito King.

Heck, men did it up until we entered the "civil" era.

Well, according to this study, that would be only the unattractive men. Hot men wouldn't need to sneak mate

Can you imagine a bunch of fish gigalos running a train on a she-fish, then she's left wondering who the father is...then she'd have to go on some fish talkshow like Rikki Lake asking for a paternity test on the show entitled, 'I had sex with 40 guppies.....and their brothers!!!'

Except in the fish world, it's the WOMEN who are flirting, not the MEN. Here it is quite the opposite

my wrath? you make me sound so evil!!

In our society sneak-mating = rape, but years ago when women were considered a man's property it was completely acceptable.

I wonder how many of us sneak-mated in past lives?

I think it's interesting that we call it rape but in the animal world it's called "sneak" mating.... who do they think they are kidding with that term??
