Hypothalamic-pituitary deficiency after Weil's syndrome: a case report.

A case of male hypogonadism after Weil's syndrome is described. Hypogonadism was the result of complete hypothalamic-pituitary deficiency. The relationship between leptospirosis and the endocrinopathy, the incidence that leptospira attacks hypothalamic-pituitary axis, and the mechanism with which the microorganism may cause damage to the pituitary and/or the hypothalamus are discussed.
