Oestradiol and oestrone can interchange. Oestradiol has a big effect on bone formation. Women past menopause have an accelerated loss of bone because they have less oestrogen.

Oestradiol also has some functions in males. Its serum concentration in men is <35pg/mL, level equivalent to that seen in post-menopausal women.
