The importance of gender-specific growth hormone (GH) secretion pattern in the regulation of growth and metabolism has been demonstrated clearly in rodents. We recently showed that GH secretion in humans is also sexually dimorphic. Whether GH secretion pattern regulates the metabolic effects of GH in humans is largely unknown.

The biochemical diagnosis of acromegaly is conventionally based on elevated plasma GH levels that fail to suppress after an oral glucose load. We studied 16 newly diagnosed patients with acromegaly with normal mean plasma GH but elevated age and gender-adjusted plasma IGF-I concentrations (476 +/- 29 microg/liter, mean +/- SE). Plasma GH was sampled every 10 min for 24 h, and an oral glucose tolerance test was performed.
