Which gender is more active in the womb?

One study, published in 2001 in the journal Human Fetal and Neonatal Movement Patterns, found that boys may move around more in the womb than girls. The average number of leg movements was much higher in the boys compared to the girls at 20, 34 and 37 weeks, that study found.

Do boys reach milestones later than girls?

Conclusions: Female fetuses grow considerably slower than male fetuses, and these differences are observed from early gestation. However, the female fetus is not merely a smaller version of the male fetus, but, rather, there is a sex-specific growth pattern for each of the individual fetal biometric indices.

Why are boys more delayed?

This study suggests that high prenatal testosterone levels are a risk factor for language delay in male children. In contrast to the increased risk for delay in males, higher levels of testosterone appeared to reduce the risk of language delay among females.

What age is late to start puberty for boys?

Boys can start puberty at a wide range of ages, with 95% starting between the ages of 9 and 14, so we consider puberty delayed when it has not started by age 14. The earliest sign of puberty in boys is enlargement of the testicles, followed by growth of the penis and pubic hair.
