Urinary testosterone and epitestosterone excretions in women with idiopathic hirsutism.

Urinary testosterone and epitestosterone were determined in 90 normal healthy women and in 90 women with idiopathic hirsutism, both groups aged between 16 and 46 years. Testosterone and epitestosterone excretion values were above the normal range in 27 of the 90 hirsute women (30%), and these 27 women had much more prominent hair growth than the others. When these results were statistically analysed according to the age groups or for all ages as a whole, they were found to be highly significant (P less than 0.0005). Therefore, it is concluded that the estimation of urinary testosterone and epitestosterone could be meaningfully applied to study the androgen status of hirsute women.
