Male Maturity Shaped by Early Nutrition
September 13, 2010
A new Northwestern University study makes a strong case for nurture's role in male to female differences--suggesting that rapid weight gain in the first six months of life predicts earlier puberty for boys. Males who experienced rapid growth as babies--an indication that they were not nutritionally stressed--also were taller, had more muscle and were stronger, and had higher testosterone levels as young adults.
