Inclusion Criteria:

decreased serum testosterone concentration below the normal range (serum T < 300ng/dL), FSH and LH levels within or below the normal range, absence of a pituitary or hypothalamic mass lesions on MRI, presence of gonadotropin response to repetitive doses of GnRH, normal smell test and normal karyotypes
