Scientists Complete First-Ever 3D Nerve Map of the Clitoris in Landmark Study

Scientists Map Clitoral Nerves in Full for the First Time

Almost three decades after scientists successfully charted the intricate nerve network inside the penis, researchers have now achieved the same milestone for one of the most understudied organs in the human body — the clitoris. This long-overdue breakthrough not only deepens our understanding of female sexual anatomy but also exposes significant gaps — and outright errors — in what medical professionals have been taught.

A Historic Gap in Medical Science

Despite being the primary organ responsible for sexual pleasure, the clitoris has been largely overlooked by the scientific and medical communities for centuries. Cultural taboos surrounding female sexuality have consistently stalled meaningful research. The organ didn't even appear in standard anatomy textbooks until the 20th century, and as recently as 1995 — in the 38th edition of Gray's Anatomy — it was dismissively described as little more than "a small version of the penis."

Melbourne-based urologist Helen O'Connell, who published the first comprehensive anatomical study of the clitoris in 1998, has long argued that this neglect was deliberate. "It has been deleted intellectually by the medical and scientific community, presumably aligning attitude to a societal ignorance," she said.

How the Mapping Was Achieved

Led by Ju Young Lee, a research associate at Amsterdam University Medical Center in the Netherlands, a team of scientists used high-energy X-rays to generate detailed 3D scans of two female pelvises obtained through a body donor programme. The resulting images revealed, in extraordinary detail, five complex branching nerve structures running through the clitoris — the widest measuring just 0.7mm in diameter.

The study has been published on the preprint server bioRxiv and is currently awaiting peer review.

"This is the first ever 3D map of the nerves within the glans of the clitoris," said Lee, who expressed astonishment that comparable knowledge about the penile glans was established as far back as 1998 — 28 years ago.

What the Scans Revealed

The scans provided a far more nuanced picture of clitoral anatomy than previously understood. The research confirmed that clitoral nerve branches extend to several areas, including:

• The mons pubis — the rounded pad of tissue sitting above the pubic bone
• The clitoral hood — the protective fold of skin covering the glans
• The labial structures — the surrounding folds of skin of the vulva

Perhaps most significantly, the research challenges an established belief that the dorsal nerve of the clitoris gradually weakens as it approaches the glans. The new imaging suggests the nerve actually remains strong all the way to its endpoint — meaning that current anatomy curricula may be teaching incorrect information.

Georga Longhurst, head of anatomical sciences at St George's, University of London, noted the particular value of high-resolution imaging within the glans, the most sensitive portion of the clitoris. "These terminal nerve branches are impossible to see during dissection," she explained.

Why This Matters for Women's Health

The implications of this research extend well beyond academic anatomy. O'Connell emphasized that understanding the sensory nerve pathways underlying arousal and orgasm carries real health significance. "Orgasm is a brain function that leads to improved health and wellbeing as well as having positive implications for human relationships and possibly fertility," she said.

Improving Surgical Outcomes

One of the most pressing applications of this nerve map relates to reconstructive surgery following female genital mutilation (FGM). According to the World Health Organization, more than 230 million girls and women across 30 countries in Africa, the Middle East, and Asia have undergone some form of genital mutilation — a practice with no medical justification that can lead to severe bleeding, infection, urinary problems, menstrual complications, and childbirth difficulties.

Approximately 22% of women who undergo reconstructive surgery after FGM report a decline in orgasmic function. A clearer picture of how far clitoral nerves extend could help surgeons reduce that figure considerably, according to Lee.

Beyond FGM reconstruction, O'Connell noted that the findings could also benefit:

• Vulvar cancer surgery
• Gender reassignment procedures
• Genital cosmetic surgeries, including labiaplasty — a procedure that surged in popularity by 70% between 2015 and 2020

Looking Ahead

Lee hopes the study will spark broader public awareness about clitoral anatomy. Inspired by London's Vagina Museum, she is planning to open a dedicated clitoris exhibition at Amsterdam University Medical Center to help educate both medical professionals and the general public.

For a field that has been sidelined for so long, this research marks a meaningful turning point — one that could ultimately improve the health, wellbeing, and surgical outcomes of millions of women around the world.
