Seat of female libido revealed

The precise part of the brain likely to be the seat of heterosexual desire in women has been revealed by experiments on mice.

The study confirms that the hormone oestrogen is vital for arousal, but only in the specific area of the brain called the ventromedial nucleus (VMN) in the hypothalamus.

Sonoko Ogawa of the University of Tsukuba in Japan and her collaborators in the US discovered this by blocking the effects of oestrogen exclusively in that part of the brain in mice. They did this with tiny slugs of genetic material called small hairpin RNAs designed to block production of oestrogen receptor alpha, the molecule where oestrogen docks on cells in the VMN and elsewhere in the body.

They used a harmless virus to shuttle the RNAs exclusively into the VMN, so that oestrogen signals would only be blocked there and nowhere else in the body. The effect was dramatic - the females refused to have sex.

“They became extremely aggressive towards males, and started biting and kicking when males approached,” says Ogawa. The females refused to mate and none of them showed the usual signs of sexual receptivity. By contrast, control females injected with neutral RNAs mated as usual. View a video of the normal mice (top) and those in which sexual receptivity was blocked (bottom).

This explains why liberal women seem to either not like sex or use it only as a weapon.

They don't have enough estrogen in the right places.

I wonder if I can get this in dart form.

We're ready for this thread!

Wine seems to have the opposite effect on the VMN, I have found.

Don't know about that, but Federal Reserve Notes work.

I hear it now, my oestrogen alpha receptor is blocked, not tonight.

Jeez you beat me to it, LOL.

[Lizavetta]

Conservative women are guilty of this as well.

Now I just have to figure out where the male sex drive comes from so I can get rid of mine. That stupid sex drive has gotten me into more trouble...

[A_perfect_lady]

Here's the seat of my libido. This man could change my screen name.

Yes, a very LARGE diamond.

So which button on the remote control unblocks the RNAs??
