Low digit ratio predicts early age at menarche in Colombian schoolgirls.
BACKGROUND The ratio between the lengths of the second and fourth fingers (digit ratio: 2D : 4D), a purported negative correlate of prenatal androgen exposure, has been inversely related to age at menarche. However, a recent study found high digit ratios in carriers of a single variant in the LIN28B gene, which has been linked to delayed menarche. METHODS We investigated the association of di...
متن کاملFactors associated with early menopause among women in Nigeria

We determined the prevalence of early menopause (EM) and its associated factors in a cohort of HIV-infected and HIV-negative controls in Jos, Nigeria. METHODS HIV-infected women accessing care in an ambulatory setting and t...
متن کاملLow Digit Ratio 2D∶4D in Alcohol Dependent Patients
The ratio of the lengths of the second and fourth finger (2D∶4D) has been described as reflecting the degree of prenatal androgen exposure in humans. 2D∶4D is smaller for males than females and is associated with traits such as left-handedness, physical aggression, attention-deficit-hyperactivity disorder and a genetic polymorphism of the androgen receptor. All of these traits are known to be c...
متن کاملLow second to fourth digit ratio in Dupuytren disease
The ratio of the lengths of the second and fourth digits (2D:4D) has been described as reflecting endogenous prenatal androgen exposure. In general, 2D:4D is lower in men than in women and has potential as a biomarker or predictor for various diseases, athletic ability, and academic performance. Dupuytren disease has digital flexion contractures and is known to predominate in men, but the patho...
