The Clitoris, Uncovered: An Intimate History
2020-03-04
According to Greek mythology, the prophet Tiresias was harassing a pair of mating snakes when Hera decided to transform him into a woman as punishment. After he had lived in this form for seven years, she changed him back. Later, when asked by Hera and Zeus to settle an argument over which sex has the most pleasure in intercourse (Hera thought men; Zeus said women), Tiresias replied, Women. Definitely women. For this impertinence, Hera struck him blind. Tiresias may have been just poking some fun at the almighty gods. Or he may have had a better understanding than most of that nerve-rich female pleasure center: the clitoris. In the history of sexual anatomy, the clitoris has long been dismissed, demeaned, and misunderstood. (Fun fact: when a French physician dissected this organ for the first time in 1545, he named it membre honteuxthe shameful memberand declared its sole purpose to be urination. The earlier origins of the word are murky. Clitoris comes from the Greek kleitoris, which has been translated as both little hill and to rub, suggesting an ancient play on words.) First off, it is not just some pea-sized nub. Around 90 percent of the clitoriss bulk lies beneath the surface. It is a sprawling underground kingdom of crackling nerves and blood-pumping vessels. Underneath the nub, called the glans clitoris, a plump wishbone shape encircles the vagina, with arms that flare out up to nine centimeters into the pelvis. And all of the parts beneath the surface are made of erectile tissue, meaning they swell with blood when aroused to become even bigger. And that under-the-surface bulk is brimming with connections. The clitoris is intimately entwined with all of the pelvic structures around it, including the urethra (the duct for urination), the vagina and the labia. This arrangement has implications in the bedroom, in the classroom and on the operating table. Understanding the full shape of the clitoris helps us to improve anatomy textbooks and better comprehend how female orgasm works. It also helps surgeons to spare crucial nerves during pelvic surgery, improve gender-affirmation procedures and repair the clitorises of women who have undergone female genital mutilation. What is crazy is that, starting with the ancient Greeks, it took humans more than 2,000 years to develop this understandingdespite the fact that about half of the population has a clitoris. Though female anatomy has not changed all that much, our understanding of it sure has. Throughout history, the clitoris has been lost, found and lost again, with male anatomists jostling one another over who deserves credit for its discovery. Yet the full clitoris is still inadequately portrayed in most anatomy textbooks. Fortunately, a few anatomical pioneers are working to change that. In 2005 Australian urologist Helen OConnell thrust the full anatomy of the clitoris into the public eye. She used microdissection of cadavers and magnetic resonance imaging of living women to reveal what only a few brave anatomists had ever dared to point out. OConnell compared the clitoris to an iceberg: beneath the surface, it was 10 times the size most people thought it was and boasted two to three times as many nerve endings as the penis. And its shapepart penguin, part insect, part spaceshipwas a marvel that could only be appreciated in three dimensions. Theres nothing quite like the shape of a clitoris, OConnell said in 2006. Today some anatomy teaching programs are starting to incorporate this expanded understanding of the organ once known as only a little hill. For the sake of women and men everywhere, heres hoping this shape wont be ignored any longer.
