Hypothalamic-pituitary-gonadal axis, prolactin, and cortisol in alcoholics during withdrawal and after three weeks of abstinence: comparison with healthy control subjects.
Serum concentrations of luteinizing hormone, follicle-stimulating hormone, testosterone, androstenedione, estradiol, sex hormone-binding globulin, cortisol, and prolactin were measured in 12 male chronic alcoholics once during withdrawal and once after 21 days of abstinence. The results were compared with those of 14 healthy volunteers. During withdrawal, luteinizing hormone, estradiol, and cortisol levels were significantly enhanced. Estradiol and cortisol concentrations fell significantly during abstinence, whereas luteinizing hormone concentrations remained elevated. The results may be interpreted as follows: the well-known inhibitory effect of alcohol on the biosynthesis of testosterone may have led to a compensatory increase in luteinizing hormone secretion, so that normal serum concentrations of testosterone were maintained. On the other hand, peripheral conversion from androstenedione to estradiol via aromatase pathways seemed to be enhanced in chronic alcoholics, at least during withdrawal. Whether this marked increase in estradiol concentrations is implicated in different clinical and psychological symptoms seen in chronic alcoholics remains to be investigated.
