About this trial

The Investigators have recently published on differences in pain sensitivity measures between cis and trans individuals in the local area. The investigators observed the anticipated differences in pain sensitivity between CM and CW (CW \> CM), but found that the TW were phenotypically similar to CW in all measures. However, the investigators did not assess hormone level, nor did the investigators recruit TM participants. Here, with the assistance of two local community group stakeholders the investigators will recruit the following groups: CM, CW, TM+T (currently taking exogenous testosterone), TW+E (exogenous estradiol), TM, and TW (n=20/group). The investigators will use quantitative sensory testing to assess sensitivity to cold, pressure, and heat via standardized protocols. Blood samples will be taken for assessment of stress and reproductive hormone levels, immune cell populations and stimulated cytokine release. Finally, questionnaires will measure pain state, quality of life (QOL), voice QOL, body image, appearance, self-reported health, masculinity/femininity, community connectedness, gender role, sleep, depression, social support, adverse childhood experiences and stigma.
