Question

Quizplus · Accepted Answer

Elevated levels of estrogen can accelerate the closure of epiphyseal plates. Estrogen is involved in the regulation of bone growth, and high levels of estrogen can stimulate the closure of the plates, leading to premature cessation of bone growth. This is why girls usually stop growing earlier than boys, as they typically have higher estrogen levels during puberty.
