Pituitary-gonadal function in adult male rats subjected to chronic water restriction

A. Armario, L. Campmany and A. Lopez-Calderon

The effect of water restriction on the pituitary-gonadal axis has been studied in adult male rats. Water restriction did not modify FSH, LH and testosterone levels. However, both LH and testosterone responses to acute noise stress were impaired by water restriction. It was unlikely that the inhibition of the pituitary-gonadal response to stress was due to an alteration of the circadian pattern of LH since no evidence for such a daily rhythm was found in either of the two experimental groups. The effects of water restriction on the pituitary-gonadal axis appear to be at least partially a consequence of the resulting reduction in food intake, so that the pituitary-gonadal response to stress would be a more sensitive index of abnormalities induced by protein-calorie deficit than basal concentrations of LH, FSH, or T.
