The human clitoris is a scientific iceberg, each bodily and figuratively.
Previously, analysis on our species’ clitoris has been superficial at best, and even the tiny bit that we predict we all know now is just not at all times proper.
The clitoris is commonly mentioned to deal with 8,000 nerve endings – ‘double’ that of the penis – however new findings, offered at a scientific assembly in October, counsel that is a severe underestimation of each intercourse organs.
The research is just not but peer-reviewed, however no less than the outcomes are on monitor to be correctly scrutinized.
The numbers most frequently cited for the innervation of the glans penis and glans clitoris derive from outdated research on – watch for it – cows; the outcomes had been merely co-opted for human anatomy.
And so these numbers have persevered for many years. Blair Peters, a plastic surgeon at Oregon Well being and Science College’s College of Medication, thinks it is about time scientists lastly discovered the proper quantity.
Peters focuses on gender-affirming care, and his work will depend on a deep understanding of human intercourse organs. To conduct additional analysis, Peters obtained clitoral nerve tissue from seven transmasculine volunteers present process gender-affirming genital surgical procedure in his follow.
Beneath a microscope, Peters and his colleagues counted a median of 5,140 nerve fibers within the dorsal clitoral nerve, and the clitoris has two of those.
Taking into consideration the total vary of samples studied, the whole variety of nerve endings innervating the whole wishbone-shaped organ ranges from 9,852 to 11,086 fibers.
Peters’s research is the primary to report the variety of nerve fibers within the human dorsal clitoral nerve and approximate the variety of nerve fibers innervating the human clitoris.
“It is startling to consider greater than 10,000 nerve fibers being concentrated in one thing as small as clitoris,” says Peters. “It is significantly shocking if you examine the clitoris to different, bigger constructions of the human physique. “
The median nerve, which runs by way of the hand, is thought for having excessive nerve fiber density, explains Peters. It has about 18,000 nerve fibers, but it surely’s additionally an entire lot larger than a roughly 10-centimeter-long (4 inches) pleasure organ.
So how’s that innervation examine to the top of a male penis? Peters plans on discovering out.
Whereas it is typically mentioned that the clitoris is twice as delicate as a penis, there’s extra nuance to the numbers than that. Each intercourse organs have the same embryological origin, which suggests they in all probability comprise roughly comparable numbers of whole nerve endings.
What’s almost definitely completely different is how densely concentrated these nerve endings are in sure spots.
Initial studies counsel, as an illustration, that the tip of the clitoris has higher variability in nerve density than the glans of the penis. In easy phrases, that in all probability means some components of the clitoris are additional delicate.
Peters hopes that a greater understanding of how intercourse organs are innervated can in the end assist surgeons with profitable reconstructions of the clitoris and penis, not just for gender-affirming functions but in addition for repairing situations of genital mutilation.
“There’s one thing profound about the truth that gender-affirming care changing into extra commonplace additionally advantages different areas of well being care,” Peters says.
“A rising tide lifts all boats. Oppressing or limiting transgender well being care will hurt everybody.”
Peters offered the findings at a joint scientific assembly of the Sexual Medicine Society of North America and the International Society for Sexual Medicine.
