Popis: Background The integrity of the neural pathways that link genital sensitive areas to the brain and the correlation with subjective sensations in transgender women with gender dysphoria after gender affirming surgery (GAS) have not been explored in detail and remain controversial, so far. Aim To test with electrophysiology the integrity of the nervous paths after GAS, and to explore the relationship between genital sensitivity and self-perceived orgasmic intensity in transgender women after GAS. Methods Six patients who underwent GAS between 2016 and 2019 were enrolled in the study, and the evaluation of genital and pelvic neural pathways was performed. Outcomes Genital sensory thresholds (at clitoral, vaginal, and anal sites) investigated by Somatosensory Evoked Potentials (SEP) and the intensity of orgasm (measured by a psychometric tool, the Orgasmometer) were combined to obtain an objective and subjective evaluation. Results SSEPs confirmed the integrity of the large diameter, dorsal column-lemniscus pathway subserving the genital area after GAS. Perceptual Threshold (PT) values were much lower at the neoclitoris compared to neovagina and anal sites. There was no correlation between Orgasmometer and SEP at anal and neovaginal level, while a trend was found at clitoral level. Clinical Implication These findings could lead clinicians to a better understanding of postsurgical sexual life in transgender women in order to develop surgical techniques that could focus more on functional aspects of neovagina and neoclitoris. Strengths & Limitations Limitations: study very preliminary/exploratory; small number of patients; no long-term follow-up. Strengths: first assessment of sensory pelvic floor innervation in transgender women after GAS; use of objective methods; first attempt at correlating objectives findings to subjective experience of the sexual orgasm. Conclusions Our evaluation showed that SSEPs is a good indicator of neural sensitivity, especially in neoclitoris, and that these measurements were consistent with the analysis of self-perceived orgasmic intensity.
