Sexual differentiation leads to the development of distinctive anatomical structures (e.g., gonads and genitalia); it also produces less obvious anatomical shifts in brain, bones, muscles, etc. This study is a retrospective analysis of growth patterns in the hands in relation to sex and sexual orientation. Using data from three published studies, we analyzed four hand traits in adults: hand width, hand length, second digit length, and fourth digit length. Using these measurements, we derived… 

Sex Differences in Directional Asymmetry of Digit Length and its Effects on Sex Differences in Digit Ratio (2D:4D)

TLDR
Based on six samples totaling about 3,000 individuals, the present study replicated the first finding of Martin, Puts, and Breedlove (2008), which found leftward bias was more frequent among men and rightward bias more frequently among women, and replicated the second finding, which was smaller by orders of magnitude and not significant.

TLDR
This study investigated the magnitude and cross-sample consistency of sex differences in all six possible digit ratios and in four novel relative finger-length measures suggested by Loehlin, Medland, and Martin as possibly superior to digit ratios for discriminating between the sexes.

Digit length ratio (2D/4D): comparing measurements from X-rays and photographs in field voles (Microtus agrestis)

TLDR
2D/4D appears to be a rather species- and method-specific measure and researchers should be careful when generalising its applicability to study early hormonal effects in vertebrates.

Pubertal Stress and Nutrition and their Association with Sexual Orientation and Height in the Add Health Data

TLDR
Prenatal mechanisms are likely better candidates for explaining the height difference between gay men and heterosexual men, as well as stress, given that stress has been associated with sexual minority identification and with lower height.

Side-specific effect of yolk testosterone elevation on second-to-fourth digit ratio in a wild passerine

TLDR
This is the first study which shows experimentally that early testosterone exposure can affect second-to-fourth digit ratio in a wild population of a passerine bird.

THE EFFECTS OF FACIAL SYMMETRY AND SEXUALLY- DIMORPHIC FACIAL PROPORTIONS ON ASSESSMENTS OF SEXUAL ORIENTATION

This study examined how perceptions of a person’s sexual orientation may be influenced by facial bilateral symmetry and sexually-dimorphic facial proportions thought to be influenced by sex hormones.

Second to fourth digit ratio (2D:4D) and concentrations of circulating sex hormones in adulthood

TLDR
There were no strong associations between any adult circulating concentration of sex hormone or SHGB measured in adulthood and 2D:4D, and these results contribute to the growing body of evidence indicating that 2D:[4D]4D is unrelated to adult sex hormone concentrations.

Sex hormones and finger length What does 2 D : 4 D indicate ?

Much recent research has focused on the ratio of the lengths of the second to fourth manual digits (2D:4D) as a predictor of the degree of expression of sexually dimorphic and other

Finger-length ratios and sexual orientation

TLDR
The androgen-sensitive pattern of finger lengths is examined, and there is evidence that homosexual women are exposed to more prenatal androgen than heterosexual women are, and men with more than one older brother, who are more likely than first-born males to be homosexual in adulthood, are exposure to more pregnancies than eldest sons.

Masculinized Finger Length Patterns in Human Males and Females with Congenital Adrenal Hyperplasia

TLDR
Results are consistent with the idea that prenatal androgen exposure reduces the 2D:4D and plays a role in the establishment of the sex difference in human finger length patterns, and finger lengths may offer a retrospective marker of perinatal androgens exposure in humans.

TLDR
The results support the notion that sexual orientation in some men and women has an early neurodevelopmental basis, but the factors responsible for the handedness-sexual orientation association require elucidation.

Dermatoglyphic asymmetry and sexual orientation in men.

TLDR
An association was observed between leftward dermatoglyphic asymmetry and an increased incidence of adextrality in homosexual men, but not in heterosexual men, consistent with a biological contribution to sexual orientation.
