A Novel Mouse Model for Investigating the Effects of Gender-affirming Hormone Therapy on Surgical Healing.

ABSTRACT: Wound healing problems are a major cause of morbidity for gender-affirming surgery (GAS) patients. Prior studies have shown sex differences in wound healing may exist. We hypothesized exogenous testosterone supplementation may impair post-GAS wound healing and developed a model to investigate this phenomenon. Mice were randomized by hormone regimen and gonadectomy (OVX). Gonadectomy or sham occurred on day 0 and mice were assigned to no testosterone (-T), mono- or bi-weekly (T/2T) testosterone groups. Dorsal splinted wounding occurred on day 14 and harvest on day 21. Serum testosterone levels were quantified with mass spectrometry. Tissue underwent analysis with planimetry, qPCR, ELISA, and immunofluorescence. Mean testosterone trough levels for bi-weekly regimen were higher compared to mo
