Recent study have found men, on average, tend to be taller and more muscular than females, and the magnitude of that difference appears to be the result of nutrition within the first six months of an infant male’s life.
Most people are unaware that male infants in the first six months of life produce testosterone at approximately the same level as an adult male.
“In the last 20 years, a lot has been learned about a process called developmental plasticity — how the body responds early in life to things like nutrition and stress. Early experiences can have a permanent effect on how the body develops, and this effect can linger into adulthood. There is a lot of evidence that this can influence risk of diseases like heart attack, diabetes and hypertension — really important diseases.” says Scientists.
