A retrospective study analyzing etiological, clinical and hormonal aspects in a population of 45 patients (14 males and 31 females) with permanent hypogonadism was performed, the most important findings were: 1) The most common cause of hypogonadism was gonadal failure (60% of all patients). This included-twenty-three females and four males. Eighteen patients had XO, two XY and two more XX gonadal dysgenesis. In the remaining cases, three patients had bilateral agonadism and two had testicular atrophy secondary to radiochemotherapy. 2) Eighteen patients had hypogonadotropic hypogonadism (40% of the cases). Ten were males and eight females. Eleven patients had gonadotropin deficiency associated with other pituitary dysfunctions. Deficiency of GH was found in all cases. TSH in ten, ACTH in nine and ADH in five. An increase in prolactin was observed in seven patients. The etiology of the hypopituitarism was intracranial tumors in five cases, idiopathic in three, perinatal hypoxemia in two and hypoplastic pituitary in one. In the remaining seven cases, isolated gonadotropin deficiency was found. Four cases were idiopathic, two cases had demyelinating diseases and one beta-thalassaemia. 3) Mean levels of testosterone were 4.20 +/- 6.5 (0, 20) pg/ml. Meal levels of estradiol of the total group, gonadal failure patients and those with hypogonadotropic hypogonadism were 8.51 +/- 14.7 (0, 50), 9 +/- 16 (0, 50) and 7.12 +/- 10.98 (0, 29) pg/ml, respectively. 4) Mean basal levels of LH and FSH in patients with gonadal failure were 35.57 +/- 60.66 (5, 320) and 53.19 +/- 53.92 (4, 230) mUi/ml, respectively. In hypogonadotropic hypogonadism patients, mean basal and peak levels of LH were 0.98 +/- 1.24 (0, 5) and 3.45 +/- 3.94 (0, 12) mUi/ml, respectively. Mean basal and peak levels of FSH after LHRH stimulation were 1.43 +/- 1.88 (0, 6) and 3.85 +/- 4.85 (0, 17) mUi/ml, respectively.
