Twenty-first-century medicine has mapped many anatomic puzzles and now can pinpoint the tiniest DNA mutations. Yet gaps remain — especially in our understanding of the female body. Nearly 30 years after researchers charted the penile nerve network, scientists have produced the first 3-D map of nerves inside the clitoral glans, said Ju Young Lee, PhD, neuroscientist at Amsterdam University Medical Center, Amsterdam, Netherlands, opening new lines of research into female pleasure and other women’s health issues.

As reported on bioRxiv, micrometer-scale computed tomography images of the female pelvis were obtained using a synchrotron radiation x-ray source. These unique data revealed the complex path of the dorsal nerve of the clitoris, the main sensory nerve of this organ.

In this context, gynecologist Miriam Al Adib, MD, PhD, told El Médico Interactivo, part of the Medscape Professional Network, “This study provides a more detailed and precise description of the innervation of the clitoris, identifying nerve pathways and branches that were not well characterized until now, especially in relation to deep and periurethral structures.” 

Clitoral Nerve Network

The study observed nerve trunks inside the clitoral glans with maximum diameters ranging from 0.2 mm to 0.7 mm. These trunks showed a branching, tree-like pattern that projected toward the glans surface. The scans also showed that some branches of the dorsal nerve of the clitoris split to innervate the clitoral hood and the mons pubis (a rounded mass of fatty tissue above the pubic bone, often called mons veneris or “mound of Venus”). Finally, the researchers demonstrated that the posterior labial nerve, a branch of the perineal nerves, innervates the area surrounding the clitoris and the labial structures.

Obtaining high-resolution images of the inside of the glans — the most sensitive part of the clitoris — is unprecedented because these terminal nerve branches cannot be seen during dissection.

For that reason, Al Adib emphasized that the work “reinforces the idea that the clitoris is a complex organ, with significant internal extension and a neurosensory network broader than what traditional anatomy textbooks have described. This higher level of anatomic detail makes it possible to better understand its functional organization and its vulnerability in different clinical contexts.”

Advances for Women’s Health

Earlier studies suggested that the dorsal nerve of the clitoris tapered as it approached the glans. The recent CT scans contradict that traditional anatomic notion, revealing that the nerve retains its full intensity up to its terminal segment.

This advance in understanding the clitoris is particularly important. “More precise identification and characterization of clitoral innervation allow a deeper look at the neuroanatomic mechanisms involved in the female sexual response,” the gynecologist said.

The implications extend beyond female pleasure. As the study notes, the findings have an immediate impact on vulvar surgical procedures, such as gender-affirming surgery and reconstructive surgery after female genital mutilation.

Al Adib discussed these issues. For one, a more detailed knowledge of clitoral innervation is especially relevant in vulvar oncologic and reconstructive surgery, where preserving neurosensory function has a direct effect on patients’ quality of life. 

She added that “in cases of female genital mutilation, it can contribute to developing reconstructive techniques aimed at functional recovery and not only morphologic recovery.”

In gender-affirming surgery, this information is crucial to optimizing the preservation of sensitivity. “Regarding so-called cosmetic genital surgeries, these findings reinforce the need for extremely cautious and well-informed decision-making, underscoring the potential risks to sensitivity and sexual function when procedures are performed without thorough anatomical knowledge,” she concluded.

New Paths to Female Pleasure

What Al Adib highlighted most was that “this finding helps explain the involvement of different sensory territories in the perception of pleasure and in the generation of orgasm, as well as the interindividual variability observed in sexual response.”

It is a late first step and a reminder of how much remains to be learned. “There are still significant gaps in our understanding of anatomic variability, neurofunctional integration, the influence of hormonal and other physiological or lifestyle factors, and how these translate into clinical practice. This study is not the end of the line, but rather a foundation upon which to develop new lines of research that will improve both clinical approaches and the training of healthcare professionals,” the expert said.

For that reason, Al Adib stressed that this type of research has structural value for medicine: “It contributes to placing women’s sexual health on a rigorous scientific level and correcting historical inequalities in the production of knowledge. Progress in this field not only improves clinical care but also has implications in terms of quality of life, rights, and health equity.”

Gender Bias in Biomedical Research

The first anatomic study of the clitoris dates back to 1998, when — almost in parallel — researchers achieved a truly detailed understanding of the penis. That nearly 30-year gap between mapping the nerve networks of male and female genitalia is a worrying sign of the gender bias that persists in biomedical research — a bias with real consequences for patients’ lives.

“While the anatomy and physiology of the penis have been studied in detail, the lack of equivalent research on female genitalia has had scientific and clinical consequences. It has led to an incomplete understanding of female sexuality, limited innovation in surgical techniques that respect function, and contributed to deficient sexual education based on incomplete or incorrect models,” Al Adib said.

The clitoris was not just a forgotten organ; it is a structure far more complex, extensive, and relevant than decades of male-biased science had imagined.
