Psychometric and Faciometric Support for Observable Facial Feminization in Gay Men

The studies offer objective support for a more feminized facial phenotype in gay males that is difficult to explain through cultural or behavioral cues.

Association of the index (2nd) and ring (4th) digit ratios with some physical attributes in Ebira Ethnic Group of Nigeria

The results show a positive correlation between the digit lengths andheight, weight, and BMI in both males and females but the 2D:4D digit ratio has no relationship with height, weight or BMI of an individual from the people of the Ebira tribe of Nigeria.

Anthropometric Study of the Index (2 nd ) and Ring (4 th ) Digits in Ebira Ethnic Group of Nigeria

The Anthropometric Study of Index (2D) and Ring (4D) Digits of Ebira tribe of Nigeria was carried out to determine the values of the 2D and 4D digit ratios and correlate them with other

Scientometric Analysis and Bibliography of Digit Ratio (2D:4D) Research, 1998–2008

Comparative citation analyses show that 2D:4D research presently is commensurate in size and importance to evolutionary psychological jealousy research, but has grown faster than the latter field.

The Human Sexual Response

Sex dimorphism in digital formulae of children.

Test for a sex difference in the relative lengths of the finger bones, including the second-to-fourth digit ratio (2D:4D), using left-hand radiographs taken in young children indicate that relative digit lengths are sex-dimorphic in children, and suggests that 3D: 4D may be a better marker of perinatal sex differentiation.

Measuring feminine gender identity in homosexual males

The appropriateness of measuring “femininity” in homosexual males by means of the usual masculinity-femininity tests is questioned and an attempt was made to arrive at a more appropriate scale by first assembling a nucleus of F.G.I. items of high clinical face validity which later could be extended by adding items strongly correlated with this nucleus.

Finger length and distal finger extent patterns in humans.

The sexual dimorphism in finger measures is more strongly expressed in the distal extent of fingertips than in the length of fingers, with smaller between-finger differences for females than for males.

LISREL 8 analyses showed that self-ascribed masculinity–femininity did not mediate the strong relation between sexual orientation and GD for men or for women.

Sex-Specific Finger-Length Patterns Linked to Behavioral Variables: Consistency across Various Human Populations

With samples from Brazil, Canada, India, Turkey, and Korea, it was shown that patterns of distal extent of finger tips are similar across different human populations, and consistent sex differences were found across the samples.

Finger-Length Ratios in Female Monozygotic Twins Discordant for Sexual Orientation

Differences in 2D:4D ratio suggest that MZ twins share virtually the same genes, and lower ratio in lesbians is a result of differences in prenatal environment.

Relative Lengths of Fingers and Toes in Human Males and Females

For both homosexual females and homosexual males, nearly all of the length ratios for fingers were intermediate to those for heterosexual females and heterosexual males; that is, the ratios of homosexual females were masculinized and those of homosexual males were hypomasculinized, but few of these differences were significant.
