Effects of administration of 17beta-oestradiol on serum leptin levels in healthy postmenopausal women.

Objective: Women have higher leptin levels than men at a certain degree of adiposity. The role of oestrogens in the regulation of serum leptin levels remains inconclusive. The aim of the present study was to investigate the effect of unopposed oestrogen replacement therapy, during two months, on serum leptin levels in postmenopausal women.
