Researcher Juyoung Lee has published the first complete three-dimensional map of the clitoral nerve network, using synchrotron imaging to render every nerve pathway in high resolution. [1] The equivalent map for penile nerves was completed in the 1990s. The gap is thirty years.

The clinical consequences of that gap are not theoretical. Surgeons performing pelvic procedures — hysterectomies, prostatectomies, gender-affirming surgeries — work near structures whose nerve anatomy has until now been understood only partially and through two-dimensional histological sections that could not capture three-dimensional branching. [1] Nerve damage in these procedures is a known complication, one that patients are counseled about but surgeons could not fully predict because the map did not exist.

Lee's synchrotron technique passes high-energy X-rays through tissue samples, generating image stacks that can be computationally reconstructed into three-dimensional models. [1] The result is a full-resolution map of a nerve system that supplies one of the most densely innervated regions of the human body.

The research also carries implications for sexual medicine. Persistent genital arousal disorder, reduced sensation following pelvic surgery, and conditions affecting orgasmic function have all been studied without the foundational anatomical knowledge this map now provides. [2]

The thirty-year lag mirrors documented patterns in medical research funding: female anatomy has historically received less research investment than male anatomy, a gap that the National Institutes of Health has formally acknowledged but not closed. [1] Juyoung Lee's work does not close the funding gap. It closes the knowledge gap for this structure, which is a start.
