Incorporating Information from Neuroscience and Endocrinology Regarding Sexual Orientation into Social Work Education

ABSTRACT

The brains of heterosexual males and heterosexual females are different. Moreover, the brains of gay men are similar to those in heterosexual females, whereas the brains of lesbians are similar to those in heterosexual males. Gender-atypical features in gays and lesbians are not limited to brain structures but extend to other physical features (auditory function, finger print patterns, relative size of index and ring fingers) and interest patterns and behaviors. The research supporting these postulates is reviewed. The gestational processes that might explain the differences in brain structure and function corresponding with sexual orientation are reviewed. A discussion of the physiological bases for the expression of gender-related traits and a discussion of factors contributing to sexual identity are provided. Throughout the article, alternative ways to think about gender are suggested. The importance of integrating the information presented in this article into the curriculum of social work education is explained.
