LHRH test in Bartter's syndrome before and during treatment with prostaglandin synthesis inhibitors.

LHRH tests were performed in two children with Bartter's syndrome before and during treatment with prostaglandin synthesis inhibitors. Before treatment, in patient 1 both basal and peak FSH and LH levels were elevated; in patient 2 basal and peak FSH levels were above the normal range, while basal and peak LH levels were normal. During treatment with an inhibitor of prostaglandin synthesis, abnormal values decreased into the normal range. These results support a possible role of endogenous prostaglandins in regulating gonadotrophin secretion in humans.
