[The estrogen-androgen profile is unchanged in men with cholelithiasis]. / Le statut estro-androgénique n'est pas modifié chez les hommes atteints de lithiase biliaire.

ABSTRACT

It is well established that cholelithiasis is more frequent in women than in men. This difference is usually explained by the effects of estrogens and progesterone on the metabolism of bile acids, biliary cholesterol secretion and saturation, and gallbladder motility. Another explanation could be a protective effect of androgens against cholelithiasis in men. To test this hypothesis, we determined the hormonal, androgenic and estrogenic, status of 15 male patients with asymptomatic gallstone disease and in 15 control patients with normal gallbladder matched for age and body weight. No significant difference in the plasma concentrations and the urinary excretion rate of sex hormones (testosterone, dihydrotestosterone, androstenedione, testosterone and androstanediol glucuronides, estradiol, estrone, total estrogens), as well as in the plasma sex hormone binding globulin, was found between the 2 groups of patients. The development of cholelithiasis in men, therefore, does not appear to be related to modification of sex steroids.
