Pituitary responsiveness to the intravenous injection of synthetic luteinizing hormone releasing hormone (LHRH) was studied in a female patient with Prader Willi syndrome and the response was compared with that obtained in prepubertal and pubertal subjects. LHRH caused the release of minimal amounts of LH and FSH in Prader Willi syndrome as compared with the LHRH response of prepubertal and pubertal female children. From these observations it is concluded that hypogonadotropism in Prader Willi syndrome may be due to a hypothalamic lesion associated with impaired or limited pituitary responsiveness.
