īut one in 10 women has never had an orgasm – and most, at some point, will have “a hard time” reaching orgasm with a partner, says Wolf. It is the only known body part with the sole purpose of pleasure. “Clitoris” dates back to the 17th century and could derive from words for “sheath”, “key” or “latch”, or “to touch or tickle”, says Wolf. The first recorded use of the word “clit” was in America in the 1950s. It was only in 2009 that a small team of French researchers carried out the first sonographic mapping of an erect clitoris, even though the technology to do so had existed for years. Understanding has been frustrated by historical heteronormative studies of the female anatomy that assumed stimulation by a penis was necessary to orgasm Wolf blames Freud. “You can come from these different places that are all using the clitoris but using it in different ways,” says Wolf. G-spot and penetrative orgasms are clitoralīoth stimulate internal parts of the clitoris. When you’re aroused, they curl around “and give your internal body a little bit of a hug”. When at rest, the “arms”, or corpora cavernosa, of the clitoris’ body extend straight out towards your thighs.
It’s not “a zero to 100 situation”, says Wolf, but as you draw closer to orgasm, it increases in size. They can swell as much as 300 per cent when engorgedĬlitorises range from 7-12 cm in length and swell by 50 per cent to 300 per cent when engorged when aroused. “All those little pieces are working together to create the amazing sensations that anyone with a clitoris feels when they’re having orgasms.” The actual vaginal tunnel has almost no sensation at all – giving birth through something as sensitive as a clitoris would be “excruciating”, says Wolf. A clitoris is made up of 18 distinct parts – a mixture of erectile tissue, muscle and nerves. That’s double the number of those in a penis. “From there, all this fabulous magical stuff is happening beneath the surface.” There are more than 8,000 nerve endings in the tip of the clitoris alone “The part that we’re seeing and feeling is just this tiny little glans that creates the head of the clitoris,” says Wolf. Mostly invisible below the surface, wrapping around the vaginal tunnel and extending out towards the thighs. The vesicles in these atypical posterior pituitary nerve endings may be true neurohumor-containing, "synaptic" vesicles.Hooked into the foyer of the Sydney Opera House, she said, it seemed to do the trick: “Everyone wanted to give it a bit of a hug.”Īnd now that the giant, golden clitoris has got your attention, here are 10 facts Wolf wants you to know. Smaller, apparently nonneurosecretory nerve endings, lacking NSG but filled with small vesicles, are occasionally seen in sections from whole gland. A fraction rich in microvesicles, but containing some NSG membranes, was prepared by density-gradient centrifugation of an osmolysate of neurosecretosomes. Microvesicles, 40–80 mµ diameter and contained in typical neurosecretory cell terminals, are believed to be degradation products of membrane ghosts of depleted NSG electron micrographs indicative of this transformation are presented. Although complete separation of VP and OT was not achieved, the findings suggest that VP and OT are each stored in a different species of nerve ending and support the hypothesis that a given neurosecretory cell synthesizes, stores, and secretes only one of the peptide hormones.
No morphological differences were apparent in neurosecretosomes among the three subfractions.
The VP/OT ratio increased from the lightest to the densest fraction, indicating that VP is localized to denser and OT to lighter neurosecretosomes similar results have been obtained previously for subfractions of neurosecretory granules (NSG). The three subfractions, each shown to be nearly homogeneous populations of neurosecretosomes by means of electron microscopic and enzymic criteria, differed from each other in their vasopressin/oxytocin (VP/OT) ratios. Neurosecretosomes were subdivided into three fractions by density-gradient centrifugation. 15% of the nerve terminals in the gland were isolated as neurosecretosomes, as estimated from determinations of lactic dehydrogenase, a soluble, cytoplasmic enzyme. Subcellular fractions of the bovine posterior pituitary, including one composed almost exclusively of pinched-off nerve endings (neurosecretosomes), were characterized electron microscopically, hormonally, and enzymically.
