Differences in finger length ratios between self-identified "butch" and "femme" lesbians.

Biological and psychosocial determinants of male and female human sexual orientation.

Some propositions on male and female sexual orientation will be considered. Some of these are established; others are more speculative. The aim is to offer some notes towards a coherent, comprehensive theory of sexual orientation. 1. The distinction between butch and femme lesbians seems real rather than a social construct. 2. High levels of prenatal steroid hormones seem to be causally associa...

Butch/Femme differences in substance use and abuse among young lesbian and bisexual women: examination and potential explanations.

Homosexual people were more likely than heterosexual people to mention traits related to sex typicalit...

Queer Time, Affective Binds: An Erotohistoriography of Butch/Femme

Sexual dimorphism in digit length ratios of the second to fourth digits (2D:4D) in Blanford's fringe-toed lizard Acanthodactylus blanfordi Boulenger, 1918 (Sauria: Lacertidae) in the south of Iran

Finger length ratios are organized during embryonic development of fingers as they exposed to sex steroid hormones, and may show varying degrees of sexual dimorphism between males and females in different animal groups. Among all the finger length ratios calculated in a sample, the ratio between the second to fourth fingers (2D: 4D) is the most important one. In this study, the 2D:4D ratios in ...
