The Big Think, via nc links:

Gregg Adams, lead author of the paper, discovered that a protein called the ovulation-inducing factor (OIF) sends a signal to the female brain to release hormones.  Those hormones then set up the body to ovulate, no matter where in her cycle that female might be.  He first saw it 10 years ago in camels.  And since this protein is also one that's been shown to play an important role in normal neuron function, he was intrigued.
Adams and colleagues have now shown that this protein helps to stimulate ovulation in other mammals including llamas, koalas, rabbits and cats, elegantly documenting how OIF signals the brain to cue up ovulation.
I find this study very interesting (and, as a woman, admittedly, vaguely frightening).  This work, of course, has potential implications for our understanding of fertility and infertility--and may also identify new targets for contraception.  It might also explain a lot of so-called "Ooops" babies.

Interesting.  That could put a hurting on the rhythm method.  Not much protection if the body can be made to ovulate.  Of course, much of the evidence was that it didn't work anyway.  But how would a bunch of celibate males know anyway?
