Primary Outcome Measures:
  • change in adrenal androgens [ Time Frame: 1 day ]

Secondary Outcome Measures:
  • urinary androgen excretion [ Time Frame: 1 day ]
  • glucocorticoid metabolism and urinary glucocorticoid excretion [ Time Frame: 1 day ]

Enrollment: 13
Study Start Date: December 2006
Study Completion Date: May 2008
Primary Completion Date: May 2008 (Final data collection date for primary outcome measure)
Detailed Description:

Free fatty acids (FFA) are known to play an important role by inducing insulin resistance and metabolic disturbances in obesity and type 2 diabetes. In addition, FFAs seems to have a stimulatory effect on adrenal androgen precursors in men. However, the effect of FFAs on androgen precursors and androgens in women is yet unknown.

Therefore the effect of increased FFAs on adrenal androgens and androgen precursors should be investigated in a randomized controlled cross-over trial.
