Digit ratio (2D: 4D) and congenital adrenal hyperplasia (CAH): Systematic literature review and meta-analysis
The ratio of length between the second and fourth fingers (2D: 4D) is commonly used as an
indicator of prenatal sex hormone exposure. Several approaches have been used to try to …

Digit ratio (2D: 4D) and maternal testosterone-to-estradiol ratio measured in early pregnancy
The ratio of index to ring finger (2D: 4D) has been hypothesised to indicate prenatal
androgen exposure, yet evidence for its validity is lacking. We report the first pre-registered …

Sexual dimorphism in titi monkeys' digit (2D: 4D) ratio is associated with maternal urinary sex hormones during pregnancy
The second‐to‐fourth digit (2D: 4D) ratio is a sexually‐dimorphic biomarker for prenatal sex
hormone exposure. We investigated whether titi monkeys (Plecturocebus cupreus) exhibit …
