Trial summary

The purpose of this study is to understand how oestrogen controls the use of fat in the liver. The hypothesis is that oestrogen is required to prevent the accumulation of fat in the liver. The mechanism may be direct or mediated by other hormones such as growth hormone, which is regulated by oestrogen. 
We wish to study the effects of oestrogen compounds called Selective Oestrogen Receptor Modulators (tamoxifen) and a drug that prevents oestrogen production (letrozole) on the secretion of growth hormone from the special gland in brain and how they control the liver production and burning of fat in men and women. We wish to compare these effects with that of natural oestrogen itself in women.
