Despite several studies in identifying the neural circuitry contributing to sexual orientation in the male-to-female (MTF) transsexuals, a neuro-imaging study for the relationships between sex arousal and sexual hormone in the postoperative MTF transsexuals versus premenopausal and menopausal women has not been attempted until now. The purpose of this study was to compare the brain activation patterns associated with visual sexual arousal in connection with sexual hormone levels in postoperative MTF transsexuals versus normal premenopausal and menopausal women using a 3.0 Tesla fMRI.
