Prenatal Testosterone.
2D:4D Ratio is associated with prenatal Testosterone
TL;DR at the bottom
Face:
Before reading this: Some things in your face are just genetic and have not much to do with prenatal Testosterone.
- Prenatal Testosterone makes everything wider
An extreme example of this is Jordan Barret:
Jordan Barret however is a extreme example of this. I chose him to resemble the morph.
.
Prenatal Testosterone is related to Sexually dimorphic facial morphology in adulthood.

Low 2D:4D ratio associated with higher horizontal facial symmetry in males, and with lower facial symmetry in females
https://www.sciencedirect.com/science/article/pii/S1090513803000849?via=ihub
---------
- Smaller and shorter + Broader forehead
- Thicker and lower brows
- Wider and shorter noses
- Broader faces (at the cheekbones)
- Bigger ears
- Higher forward growth
- More robust face
- More prominent chins (Not necessarily protruding chins. I have seen examples of this IRL)
- More masculine face in adulthood
- Higher horizontal facial symmetry
- Wider everything
------------
Body:
This is about women. I don't know if males have the same.
- Muscle efficiency.
- Higher fertility
- Higher static and explosive strength
- Thicker neck circumference
- Higher content of muscle mass, lean body mass and water (in women but probably males too).
- Higher circulating testosterone
- Higher amount of androgen receptors

I am too lazy to do behaviour. I am going to do one for testosterone too if you guys want that.

These are all the positives tho.

High prenatal testosterone: smaller and shorter foreheads, thicker and lower brows, wider and shorter noses, broader faces (at the cheekbones]), and more prominent chins
"This approach reveals that some aspects of facial masculinity are organized before puberty, suggesting they develop in response to testosterone exposure in utero (Meindl et al. 2012): individuals with lower 2D:4D ratios tend to have smaller and shorter foreheads, thicker and lower brows, wider and shorter noses, broader faces (across the zygomatic arches), and more prominent chins than individuals with higher ratios (Meindl et al. 2012; Schaefer et al. 2005)."

Body:
Lower right-hand 2D:4D ratios associated with higher sperm counts and blood testosterone levels in males; higher ratios associated with high blood levels of oestrogen, luteinizing hormone and prolactin in males and females
Low 2D:4D ratio strongly related to efficiency in aerobic exercise (endurance), weakly to strength
"Speed in endurance races is strongly related to 2D:4D, and may be one factor that underlies the link between sport and 2D:4D, but nothing is known of the relationship between 2D:4D and sprinting speed. Here we show that running times over 50 m were positively correlated with 2D:4D in a sample of 241 boys (i.e. runners with low 2D:4D ran faster than runners with high 2D:4D). The relationship was also found for 50 m split times (at 20, 30, and 40 m) and was independent of age, BMI, and an index of maturity. However, associations between 2D:4D and sprinting speed were much weaker than those reported for endurance running. This suggests that 2D:4D is a relatively weak predictor of strength and a stronger predictor of efficiency in aerobic exercise."
High 2D:4D digit ratio correlated to some forms of lower infertility in men
"The percentage of cases (males) with a 2D:4D ratio equal to or greater than 1 was specially higher among vasal agenesis and hypogonadotropic hypogonadism groups and some statistically significant differences were detected."
Low 2D:4D ratio associated with higher static and explosive strength in males, and with greater height and more body fat in females
"A negative correlation between right hand 2D:4D and vertical jumping, standing long jump, 20 m sprint, 10x5 agility and right hand grip strength in the males. As for the females, although a negative correlation was detected between right hand 2D:4D and height, a positive correlation was found between the same variable and body fat ratio (p<0.05). It can be concluded that while a low 2D:4D ratio was correlated with static and explosive strength, speed and agility in the males, it was correlated with height and body fat ratio in the females."
Low 2D:4D ratio associated with higher neck circumference in adolescents (except in obese individuals)
"There was a significant negative correlation between NC [neck circumference] and 2D:4D ratios of the individuals with normal BMI [Body Mass Index]. However, no statistically significant correlation between NC and 2D:4D ratios was observed in overweight and obese individuals."
This is about women. I don't know if males have the same.
Lower 2D:4D ratio in women associated with higher content of muscle mass, lean body mass and water
"The BMI, muscle mass, lean body mass and water in the body demonstrated higher values in men than in women. However, the fat content in men was low. It was found that the relationship exists between muscle mass, lean mass and total water content in the body and the 2D:4D finger length ratio in the left hand in women. A higher level of fetal testosterone, characterized by lower values of the 2nd to 4th finger length ratio, may be associated with a higher content of muscle mass, lean body mass and water in the body of adult women leading a similar lifestyle."
