castrated boys WILL typically be taller, due to the lack of testosterone.
I still disagree with this summation.
With this logic, women would be taller than the average male b/c they have less testosterone. Continuing with this logic, individuals with androgen insensitivity would be
much taller than the average male (The NBA would be dominated by 7 foot models with large perky breasts
). The whole reason I brought up the Jamie Lee Curtis point was to discredit this line of reasoning.
You also don't seem to realize (or recall) that testosterone 1)derived from adrenal androgen, 2)derived from peripheral conversion of estrogen is still present in eunuchs. So they don't lack testosterone, rather their E:A ratio is shifted higher. The ratio is increased further b/c estrogen stimulates the production of steroid binding globulin (SBG) which further diminishes available testosterone.
Testosterone is a big reason men are taller than women . The right amount of testosterone in puberty triggering long bone growth while at the same time having less available estrogen to trigger epiphyseal plate closure.
Finally, to be completely correct...we should really be referring to dihydrotestosterone (DHT) which is the active form of the hormone responsible for all the positive (penile development, bone growth, facial hair) and negative (male pattern baldness, prostatic hyperplasia, back hair) effects.
Testosterone ---> DHT (by 5-alpha reductase)
Testosterone ---> Estrogen (aromatase)
Estrogen ---> Testosterone (aromatase)
