Both handedness and dermatoglyphic asymmetry reflect early, prenatal influences and both have been reported to be associated with male sexual orientation; handedness has been related to female sexual orientation as well. Neurohormonal and developmental perturbation are two competing hypothesis that attempt to explain these connections. We attempted to replicate these associations and to extend dermatoglyphic asymmetry findings to women. Dermatoglyphic directional asymmetry and fluctuating… 
Fluctuating Asymmetry and Sexual Orientation in Men and Women
TLDR
Results showed that, for men, there was a significant positive correlation between three measures of FA and sexual orientation scores (SOS), and as ear breadth FA and two composite FA scores increased so did SOS on a modified Kinsey scale.
Fluctuating asymmetry, second to fourth finger length ratios and human sexual orientation

TLDR
Examining nine bilateral somatic traits in 120 healthy heterosexual and homosexual men and women found that sexual orientation did not relate to composite FA scores, which constrain the number of possible neurodevelopmental pathways responsible for sexual orientation in humans.
Fraternal Birth Order, Handedness, and Sexual Orientation in a Chinese Population
TLDR
The results showed that homosexual women are more likely to be non-right-handed than heterosexual women, regardless of how sexual orientation was defined, whereas bisexual women areMore likely to been non- right-handedthan heterosexual women whenSexual orientation was assessed via sexual attraction and sexual identity.
Born gay? The psychobiology of human sexual orientation
Sexual orientation is fundamental to evolution and shifts from the species-typical pattern of heterosexuality may represent biological variations. The growth of scientific knowledge concerning the
Hand Asymmetry in Heterosexual and Homosexual Men and Women: Relationship to 2D:4D Digit Ratios and Other Sexually Dimorphic Anatomical Traits
TLDR
The present evidence actually suggests that homosexuals have lower FA than heterosexuals, raising the question of whether the positive fitness components associated with low FA may contribute to selection that maintains homosexuality in a population.
Evidence against a Relationship between Dermatoglyphic Asymmetry and Male Sexual Orientation
TLDR
The results reported in this paper do not support any relation between dermatoglyphic asymmetry and male sexual orientation, and, thus, any hypothesis concerning a biological intrauterine contribution to adult sexual orientation somehow associated with dermatoglyPHic development is not supported.
Sexual Orientation and Fluctuating Asymmetry in Men and Women
TLDR
Although elevated levels of developmental stress appear to be linked to shifts in sexual orientation, the underlying mechanism does not seem to be connected to sex-atypical prenatal hormones.
Excess of counterclockwise scalp hair-whorl rotation in homosexual men

TLDR
The results suggest that sexual preference may be influenced in a significant proportion of homosexual men by a biological/genetic factor that also controls direction of hair-whorl rotation.
Relationships Among Childhood Sex-Atypical Behavior, Spatial Ability, Handedness, and Sexual Orientation in Men
Moderate support was obtained in a sample of 101 gay, bisexual, and heterosexual males for the perinatal hormone theory, which hypothesizes that attenuated levels of androgens during critical periods
The neurodevelopment of human sexual orientation
  • Q. Rahman
  • Medicine, Psychology

  • 2005
TLDR
Evidence is reviewed which supports the proposal that sexual orientation in humans may be laid down in neural circuitry during early foetal development and the notion that non-heterosexual preferences may reflect generalized neurodevelopmental perturbations is not supported by available data.

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.
Neurohormonal functioning and sexual orientation: a theory of homosexuality-heterosexuality.
TLDR
Evidence indicating that the process of determining human sexual orientation is fundamentally the same in all mammals is reviewed, and a theory of how the entire spectrum of humanSexual orientation is determined is proposed.
Sexual orientation and handedness in men and women: a meta-analysis.
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.
The dermatoglyphic characteristics of transsexuals: is there evidence for an organizing effect of sex hormones
TLDR
It was unable to demonstrate that the chosen dermatoglyphic variables, total ridge count and finger ridge asymmetry are related to gender identity and sexual orientation in adult transsexuals, and found no support for a prenatal hormonal influence on these characteristics.
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.
Aggressiveness, competitiveness, and human sexual orientation
TLDR
Heterosexual men were more physically aggressive than were homosexual men; no other within-sex relationship was significant and the aggressiveness and competitiveness scales yielded significant sex differences, with men being more aggressive and competitive.
Evidence against a Relationship between Dermatoglyphic Asymmetry and Male Sexual Orientation
TLDR
The results reported in this paper do not support any relation between dermatoglyphic asymmetry and male sexual orientation, and, thus, any hypothesis concerning a biological intrauterine contribution to adult sexual orientation somehow associated with dermatoglyPHic development is not supported.
Dermatoglyphic analysis of total finger ridge count in female monozygotic twins discordant for sexual orientation
This study was designed to test the hypothesis that prenatal environment contributes to the development of sexual orientation in females. The research involved a dermatoglyphic analysis of finger
Human sexual orientation. The biologic theories reappraised.
TLDR
Critical review shows the evidence favoring a biologic theory to be lacking, and in an alternative model, temperamental and personality traits interact with the familial and social milieu as the individual's sexuality emerges.
A difference in hypothalamic structure between heterosexual and homosexual men
TLDR
The measured volumes of INAH 3 indicate that INAH is dimorphic with sexual orientation, at least in men, and suggests that sexual orientation has a biological substrate.
