Females may be outwardly choosy when selecting sexual partners -- accepting or shunning mates in very public ways -- but males may get the last say in this battle of the sexes.
New research found that males can adjust the speed and effectiveness of their sperm by allocating more or less seminal fluid to copulations. The determining factor is whether the male finds the female attractive.
The study, conducted on red junglefowl, a director ancestor of chickens, adds to the growing body of evidence that males throughout many promiscuous species in the animal kingdom, including humans, can mate with many females, but chances of fertilization are greater when the female is deemed to be attractive.
Desirable female red junglefowl are easy to identify.
"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.
For the study, published in the current Proceedings of the Royal Society B, the researchers collected natural ejaculates from dominate and subordinate red junglefowl males housed at the University of Stockholm. The males had either just mated with attractive or unattractive females.
Well....duh.
Laz is back in the laboratory, apparently.
I hate you.
In her case, I believe the sperm form themselves into a hammer and a stake.
Damn you WakeUpAndVote, damn you to hell!!!
Who didn’t know that?
Mine just shrivelled up while running the other way.........

You can bet you boots if the sperm was “collected” by humans, the last thing it was was “natural.”
Somebody actually dreamed up and got paid to do this study! I’m volunteering for the human testing!
Joe, I agree with everyone else and I’ll add that I hope yours falls off because of posting that picture this early in the morning!
A valuable tip that I'll keep in mind.
RE pic: She’s beautiful, isn’t she?
I’m so sick of these stupid stories. Folks actually research this nonsense, get grants for such nonsense, believe such nonsenese, and then nonsensical news outlets publish such nonsense, and the majority of folks who read such nonsense believe the nonsense, what a bunch of nonsense.
This makes sense.
