TLDR
The results of this study highlight the need for future developmental studies of 2D:4D ratios in order to determine not only their stability and predictive value, but also to discern the mechanism connecting prenatal androgen exposure, 2D-3D ratios, and behavioral outcomes.

Digit ratio (2D:4D) and behavioral symptoms in primary-school aged boys.

Parent-Reports of Sex-Typed Play Preference in Preschool Children: Relationships to 2D:4D Digit Ratio and Older Siblings’ Sex

TLDR
Children’s 2D:4D was measured on both hands on four occasions from early infancy to early childhood providing the rare possibility to test the temporal stability of the sex difference and shows the importance of both biological and social influences on sex-typed play behavior.

Sex Differences in Rhesus Monkeys’ Digit Ratio (2D:4D Ratio) and Its Association With Maternal Social Dominance Rank

TLDR
Findings show a consistent sex difference in Old World monkeys’ 2D:4D ratio that diverges from the pattern observed in apes and humans, and suggest maternal social dominance rank modulates PAE in rhesus monkeys.

2D:4D Suggests a Role of Prenatal Testosterone in Gender Dysphoria

TLDR
The findings support the idea that high levels of prenatal T in natal females and low levels inNatal males play a part in the etiology of GD, and add to the evidence demonstrating the convergent validity of 2D:4D as a marker of prenatalT effects.

Sexual Dimorphism in Titi Monkeys' Digit (2D:4D) Ratio is Associated with Maternal Urinary Sex Hormones During Pregnancy.

TLDR
The first report of sexually-dimorphic 2D:4D ratio in New World monkeys is reported, and the results support a growing literature suggesting prenatal sex hormones may modulate offspring 2D-3D ratio.
