For nearly thirty years, the intricate web of nerves inside the penis has been known to science. It was mapped in 1998, a quiet milestone in the long history of anatomical study. Now, at last, the same detailed scrutiny has been applied to one of the most neglected organs in the human body—the clitoris.
A team of researchers in the Netherlands has produced the first-ever three-dimensional map of the clitoral nerve network, a feat that not only reveals the extraordinary complexity of the organ but also corrects fundamental errors in what doctors have been taught for decades. The work, described in a preprint on bioRxiv, promises to reshape pelvic surgery, improve outcomes for women who undergo reconstructive procedures, and finally grant scientific legitimacy to an organ long obscured by cultural taboo.
“This is the first ever 3D map of the nerves within the glans of the clitoris,” said Ju Young Lee, a research associate at Amsterdam University Medical Center, who led the study. She expressed astonishment that such a basic anatomical undertaking took so long. “A similar level of knowledge regarding the penile glans was reached back in 1998.”
A History of Erasure
The clitoris, the epicenter of female sexual pleasure, has been systematically ignored by the medical establishment for centuries. Cultural prohibitions around female sexuality stifled inquiry, and the organ was conspicuously absent from standard anatomy textbooks until well into the 20th century. When it finally appeared in the 38th edition of Gray’s Anatomy in 1995, it was dismissively described as merely “a small version of the penis.”
Dr. Helen O’Connell, a Melbourne-based urologist who published the first comprehensive anatomical study of the clitoris in 1998—the same year the penile nerve map was completed—has long been a voice of frustration.

“It has been deleted intellectually by the medical and scientific community, presumably aligning attitude to a societal ignorance,” O’Connell said. Her earlier work laid the groundwork, but the full architecture of the organ’s nerve supply remained elusive—until now.
Unveiling the Hidden Network
Using high-energy X-rays, Lee and her colleagues created exquisitely detailed 3D scans of two female pelvises donated through a body donor program. The resulting images trace the trajectory of five complex, tree-like branching nerves that run through the clitoris, with branches as fine as 0.7 millimeters across. The scans reveal a far more extensive system than previously understood.
The research shows that some clitoral nerve branches extend to the mons pubis—the fleshy mound above the pubic bone—while others reach the clitoral hood and the labial folds. Crucially, the scans challenge a long-held anatomical assumption. Earlier teachings suggested that the dorsal nerve of the clitoris gradually diminishes as it approaches the glans, the small, highly sensitive external portion that represents just 10% of the total organ. The new images demonstrate the opposite: the nerve continues robustly all the way to the tip.
“I was especially fascinated by the high-resolution images within the glans, the most sensitive part of the clitoris, as these terminal nerve branches are impossible to see during dissection,” said Dr. Georga Longhurst, head of anatomical sciences at St George’s, University of London, who was not involved in the study.
Surgical Implications
The findings are far from academic. For surgeons operating in the pelvic region—whether for vulvar cancer, gender reassignment, or elective cosmetic procedures like labiaplasty—a precise understanding of nerve pathways can mean the difference between preserving or permanently impairing sexual function. Labiaplasty, for instance, saw a 70% increase in popularity between 2015 and 2020, yet many surgeons have operated without a clear map of the nerves they risk damaging.
Perhaps the most urgent application lies in reconstructive surgery following female genital mutilation (FGM). According to the World Health Organization, more than 230 million girls and women alive today have undergone FGM across 30 countries in Africa, the Middle East, and Asia. The practice, which has no health benefits, often involves the partial or total removal of the external clitoris and labia, leading to severe bleeding, infection, childbirth complications, and lasting psychological trauma.
For the estimated 22% of women who undergo surgical reconstruction after mutilation and experience a decline in orgasmic function, this new mapping offers hope. By revealing how far the nerves truly extend—beyond what is visible externally—surgeons may be able to restore sensation more effectively.
“Orgasm is a brain function that leads to improved health and wellbeing as well as having positive implications for human relationships and possibly fertility,” O’Connell said. Understanding the sensory mechanism that feeds that brain function, she added, is essential.
A Future in the Light
Lee hopes to build on the momentum by opening a clitoris exhibition within Amsterdam University Medical Center, modeled on the pioneering Vagina Museum in London, which opened in 2019 as the world’s first bricks-and-mortar museum dedicated to gynecological anatomy.
For too long, the clitoris has existed in a shadow world—crucial to half the population’s experience of pleasure yet virtually invisible to the science that shapes medical practice. This new map does more than fill in a blank page in Gray’s Anatomy. It reclaims the organ from centuries of neglect and offers a corrective to a history of intellectual erasure.
“The clitoris has been deleted,” O’Connell said. This research, finally, restores it.
