“…Additionally, statistically significant differences were found in 2D:4D for both right and left hands depending on the category of waist circumference and WHtR. Researchers have reported that women with abdominal obesity have the lowest digit ratio values 38 . This is in line with reports suggesting that testosterone promotes fat accumulation in the waist area 11 .…”

“…There are also studies that do not show the existence of such a relationship in young women 37 , 38 as well as young women and men 39 – 42 . On the other hand, others reveal an inverse correlation between 2D:4D and BMI 43 .…”

“…Research shows that it may be positively correlated with 2D:4D 32 , 47 , negatively correlated 43 or not related 48 . In the case of waist circumference (WC) and hip circumference (HC) and their relationship—WHR researchers report both positive 32 and negative associations 36 , 38 , 40 , 43 with right and left hand 2D: 4D. Others, on the other hand, report a lack of association with 2D: 4D 41 , 48 .…”

“…Here, too, mixed results have been reported. Some authors point to positive associations between 2D:4D of the right and left hand and WHtR 32 , others suggest negative correlations between these variables 38 , 41 . Additionally, statistically significant differences were found in 2D:4D for both right and left hands depending on the category of waist circumference and WHtR.…”

Abstract2D:4D finger length ratio is a proxy of prenatal sex hormone exposure. Prenatal testosterone decreases and prenatal estrogens increase this index. In the current study we investigated whether the 2D:4D index, as a marker of the prenatal hormonal environment, is associated with the development of overweight and obesity in adults, and whether is it correlated with the rate of weight loss in patients after bariatric surgery. We tested 125 adults with obesity (BMI ≥ 30.0 kg/m2), 125 adults with overweight (BMI 25.0–29.9 kg/m2) and 153 persons with normal body weight (BMI < 25 kg/m2) of both sexes. We have found that the development of excessive body weight in men and women, and fat accumulation in the upper arms, thighs and lower legs in women with obesity (but not men) are associated with increased prenatal estrogen exposure. This relationship indicates a new area of activity in the field of obesity prevention. Moreover, it seems that the 2D:4D index (especially of the right hand) may be a useful factor in early prediction of the risk of developing excessive body weight in humans. The rate of weight loss after bariatric surgery is independent of prenatal exposure to sex hormones.

“…Для изучения значимости пальцевого индекса данные по разным возрастным когортам женщин представляют особый интерес, поскольку по многих работах выявляется тенденция более отч тливых соматических и психологических ассоциаций этого показателя именно в женских выборках, при этом старшие возраста зачастую остаются вне рамок изучения [Bakholdina et al, 2018a]. Среди соматических признаков, обнаруживающих связи с пальцевым индексом у женщин -индекс «талия-б дра» [Zurawiecka et al, 2019], степень жироотложения [Bakholdina et al, 2018a], размер груди [Ertuğrul et. al., 2020], сила кисти [Bakholdina et al, 2018b].…”

We propose and evaluate a new theory for helping to explain the evolution of endometriosis risk in humans. By this theory, endometriosis risk evolved in the context of sexual selection by males for high, relatively female-biased expression of sexually dimorphic and female-limited phenotypes associated with low testosterone and high female reproductive fitness. The theory is supported by extensive data, showing that: (a) endometriosis involves higher expression of major female-biasing genes, and lower expression of major male-biasing genes, that orchestrate prenatal sexual differentiation; (b) endometriosis and its correlates are associated with low prenatal and postnatal testosterone, both of which have female-biasing effects on traits; (c) low prenatal and postnatal testosterone, and endometriosis, are associated with relatively female-biased phenotypic expression for a large suite of sexually dimorphic and sex-limited traits; (d) relatively female-biased expression of these traits is commonly associated with higher fertility and fecundity; (e) some traits, including female facial features, vocal pitch, and breast size, fit with all of the predictions of the model, though they have yet to be studied in relation to endometriosis; and (f) traits linked with low prenatal and postnatal testosterone or high estradiol, and traits associated with endometriosis in humans, are preferred by males across multiple species of non-human mammals. Risk and symptoms of endometriosis thus appear to involve and represent, in part, maladaptive extremes of sexually selected female-limited and sexually dimorphic traits.
