Researchers at Amsterdam University Medical Center have produced the first complete three-dimensional nerve map of the human clitoris, correcting long-standing anatomical assumptions and addressing a decades-long gap in medical knowledge. The study, led by Dr. Ju Young Lee, a postdoctoral researcher in the department of obstetrics and gynaecology, used synchrotron phase-contrast CT scanning, an advanced X-ray technique capable of resolving structures down to 0.001 millimeters (about 0.00004 inches). The tissue examined came from the pelvises of two postmenopausal women who had donated their bodies to the university after death. The findings were published on the preprint server bioRxiv in March 2026 and have not yet undergone peer review.

The mapping revealed that the dorsal nerve of the clitoris, the organ's main sensory nerve, branches extensively in a tree-like pattern throughout the clitoral glans rather than tapering off as earlier models assumed. The nerve also extends upward into the clitoral hood and the mons pubis, beyond where scientists previously believed it ended. The study confirmed that the human clitoris contains more than 10,000 nerve fibers, correcting a long-standing estimate of roughly 8,000 that had been based on research conducted on cows in 1976 and repeated in medical textbooks for nearly five decades. The nerve density of the clitoris is up to 15 times greater than that of the penis.

The full clitoris is far larger than traditionally depicted in medical textbooks. Only about 10 percent is visible externally as the glans clitoridis. The remaining 90 percent is internal, consisting of the clitoral body, two crura (legs) of erectile tissue that can extend up to 9 centimeters (about 3.5 inches), and two vestibular bulbs flanking the vaginal opening.

The research addresses a substantial gap in medical knowledge. The penis was fully nerve-mapped in 1996, and that data directly informed surgical techniques for prostate surgery, penile reconstruction, and gender-affirming procedures. There are roughly 20 times more scientific papers on the penile glans than on the clitoral glans. Dr. Lee described the study as "the starting point of clitoris science" and stated that understanding the anatomy is a prerequisite for understanding how the clitoris functions. She pointed to a societal taboo attached to female sexuality as an obstacle to scientific investigation and noted that ignorance has led many people to confuse the clitoris with the vagina.

The clinical implications of the nerve map span several medical fields. In childbirth, knowledge of nerve pathways can help surgeons avoid damaging clitoral nerves during episiotomy and reduce long-term sexual dysfunction after birth. In gender-affirming surgery, accurate nerve mapping allows surgeons to preserve sensation during clitoroplasty and phalloplasty. For survivors of female genital mutilation, which affects over 230 million women and girls worldwide and is considered a human rights violation, the map serves as a guide for reconstructive surgery aimed at restoring partial sensation. The study noted that about one-fifth of women have fewer orgasms after reconstructive surgery, and the new mapping could help address that issue. The images could also help surgeons avoid nerve damage during female genital cosmetic procedures such as labiaplasty and vaginal rejuvenation, and during pelvic surgeries including hip replacements and bladder procedures. Additionally, the map provides a foundation for researching sexual dysfunction conditions such as provoked vestibulodynia and persistent genital arousal disorder.

The study has notable limitations. It examined only two postmenopausal women, so the findings may not represent the anatomy of every clitoris. Dr. Lee noted that follow-up studies with larger sample sizes and a broader range of participants across different ages would be valuable, and expressed interest in future research focusing on physiology, meaning how the organ functions, rather than just its structure. She also recommended that people use a mirror to examine their own anatomy, noting that unlike the penis, the clitoris requires a mirror for proper visual inspection.

The work is part of the Human Organ Atlas initiative, a project aiming to render all of the body's organs at a microscopic scale to provide new insights into human biology. Future studies will examine a broader range of tissue samples to better understand how clitoral anatomy changes across different stages of life.

Some context is worth noting. The clitoris itself has a long history in anatomical science. Realdo Colombo described it in 1559. Regnier de Graaf illustrated it in 1672. Georg Ludwig Kobelt documented the glans, body, crura, and bulbs in remarkable detail in 1844. Helen O'Connell's work in 1998 and 2005 corrected generations of inaccurate medical diagrams and re-established the clitoris as a complex internal erectile organ rather than a small external structure. Earlier anatomical research, including work published in 2020 and 2021, examined branching patterns and surgical risk zones related to labiaplasty and vulvar procedures. What is genuinely new in the latest research is the level of detail and precision in the imaging, which has produced one of the most sophisticated three-dimensional microscopic visualizations of the clitoral nerve network to date.
