Evidently sperm need a reason to swim upstream…

Sperm & EggEvery now and then you come across an article that just, while it seems so short, answers a lot of questions. For example this one, Sperm Travels Faster Toward Attractive Females in Discover Channel article by Jennifer Veigas. Of course the research was done on red junglefowl, a sort of chicken.

While women may be picky when choosing a mate, it seem that the male is most likely to produce more sperm with a great desire to make it to the egg if the male finds the female attractive and the more attractive the faster the sperm swim to their destination.

While this is interesting research especially for those who are trying to learn more about fertility, it does seem to be making a lot of assumptions when the chickens can’t exactly tell you that that chicken on over by the watering can is the most beautiful he’s ever seen. The researcher said:

“Female attractiveness is determined by the expression of a sexual ornament — the comb — which is phenotypically and genetically correlated to the number and mass of eggs females lay,” according to study co-authors Charlie Cornwallis of the University of Oxford and the Royal Veterinary College’s Emily O’Connor.

I don’t think that this research can really be expected to map on human behavior because I don’t think it actually maps on chicken behavior — flushed comb or not — some hens are better layers than others no matter what the rooster thinks of them. Ask any farmer? So, while interesting, I think the assumptions are flawed but then again the original papers are not available and the reported methodology just doesn’t make me think they got anything going with this line of research — but it does make you wonder….
