An anthropometric study of sexual orientation and gender identity in Thailand
TLDR
It appears the various anthropometrics inform separate biodevelopmental processes that differentially relate to sexual orientation and gender identity/expression depending on the measure in question as well as birth-assigned sex.
Personality and Sexual Orientation: New Data and Meta-analysis
TLDR
Personality differences were observed between those who identified as heterosexual, bisexual, and homosexual (gay/lesbian) on all five measured traits and there was evidence that personality differences between sexual orientation categories tend to decline with age.

Psychological sex differences have been studied scientifically for more than a century, yet linguists still debate about the existence, magnitude, and causes of such differences in language use.
Are Autism Spectrum Disorder and Asexuality Connected?
TLDR
It is concluded that asexuality and autism share various aspects, such as a possible role of prenatal factors, reference to romantic dimensions of sexual attraction and sexual orientation, and non-partner-oriented sexual desire, but future research should explore and clarify this link.
A Multi-Modal MRI Analysis of Cortical Structure in Relation to Gender Dysphoria, Sexual Orientation, and Age in Adolescents
TLDR
Effects of experienced gender were found as similarities in correlation patterns in GD AFAB and cisgender boys in age and sexual orientation (mainly T1), indicating the need to consider developmental trajectories andSexual orientation in brain studies of GD.
Inter-Network Brain Functional Connectivity in Adolescents Assigned Female at Birth Who Experience Gender Dysphoria
TLDR
The pattern of group differences and the networks involved aligned with the hypothesis that brain functional organization is different among GD AFAB (vs. cisgender) adolescents, and certain aspects of this organization relate to brain areas implicated in own-body perception and self-referential thinking.
Handedness and Birth Order Among Heterosexual Men, Gay Men, and Sao Praphet Song in Northern Thailand.
TLDR
Sexual orientation and gender identity simultaneously is investigated simultaneously via comparison of 282 heterosexual men, 201 gay men, and 178 sao praphet song-i.e., androphilic, markedly feminine males recognized as a "third" gender in Thailand to provide new insights and replicate previous findings in a non-Western sample.

Stability and Change in Sexual Orientation and Genital Arousal over Time.
Longitudinal work suggests that sexual orientation can change over time in men and women. These studies, however, may be susceptible to the bias of self-report. The current study therefore examined

Birth order and sexual orientation in women.
TLDR
Investigation of whether lesbians, like homosexual men, have a later birth order relative to heterosexual comparisons supports theories of gender-specific mechanisms in the development of sexual orientation in women and men.

TLDR
In both studies, fraternal birth order predicted same-sex attraction in men, with each additional older brother increasing the odds of homosexual attraction by an average of 38%.
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.
Genetic and environmental influences on sexual orientation and its correlates in an Australian twin sample.
TLDR
Assessment of sexual orientation and 2 related traits: childhood gender nonconformity and continuous gender identity suggested that the causal architecture differed between men and women, and provided significant evidence for the importance of genetic factors to the traits' covariation.
Early life conditions and adolescent sexual orientation: A prospective birth cohort study.
TLDR
Parental absence since birth, low prenatal family socioeconomic position, and poorer parent-child relationship were associated with later nonheterosexuality among girls, and this effect disappeared after entering all early life history factors.
Prenatal Influences on Human Sexual Orientation: Expectations versus Data
TLDR
The data indicate that human sexual orientation is sufficiently polarized that groups of lesbians show evidence of greater prenatal androgen exposure than groups of straight women, while groups of gay men have, on average, a greater proportion of brothers among their older siblings than do straight men.
Sexual Orientation in Women with Classical or Non-classical Congenital Adrenal Hyperplasia as a Function of Degree of Prenatal Androgen Excess
TLDR
The findings support a sexual-differentiation perspective involving prenatal androgens on the development of sexual orientation and are linked to the first study to relate sexual orientation to the specific molecular genotypes of CAH.
Handedness, sexual orientation, and somatic markers for prenatal androgens: Are southpaws really that gay?
TLDR
Ambidextrousness appears to be somewhat more common among females with homosexual tendencies, but left- handedness is nearly as strongly associated with heterosexual preferences, particularly in males, as is right-handedness.
