Sex differences in steroid metabolism have been clearly demonstrated in animal studies, but few studies have addressed this question in the human. Our preliminary studies suggested human sex differences in both cortisol production and metabolism. We therefore looked in more detail at indices of cortisol metabolism derived from 24 hour urinary steroid profiles in a group of 20 men and 20 women who were age-matched, drug-free and had no endocrine disorder. Steroid analysis was by high resolution gas chromatography. Men excreted more total cortisol metabolites (7620 +/- 620 v 4750 +/- 380 micrograms/24 h, p < 0.001), 11-oxo metabolites of cortisol (11-oxo FM, 4320 +/- 400 v 2890 +/- 250 micrograms/24 h, p < 0.001) and 11 beta-hydroxy metabolites of cortisol (11-OH FM, 3290 +/- 240 v 1860 +/- 140 micrograms/24 h, p < 0.001). These differences remained significant when corrected for body surface area. The ratio of 11-oxo FM/11-OH FM, an index of 11 beta-hydroxysteroid dehydrogenase (11-HSD) activity, was higher in women (1.57 +/- 0.07 v 1.31 +/- 0.06, p < 0.01). The ratios of 5 alpha/5 beta and 20-oxo/20-OH metabolites of cortisol were both higher in men (1.07 +/- 0.15 v 0.58 +/- 0.04, p < 0.01, and 2.78 +/- 0.06 v 2.27 +/- 0.11, p < 0.01), while the ratio of 20 alpha/20 beta metabolites of cortisol was higher in women (1.79 +/- 0.13 v 1.32 +/- 0.06, p < 0.01). We conclude that there are considerable sex differences in both the production and metabolism of cortisol in healthy men and women. In particular, the data are consistent with a sex difference in 11-HSD activity, with relatively greater conversion of cortisol to cortisone in women.

Our purpose was to investigate the effects of electroacupuncture (EA) therapy on body weight and on levels of serum insulin, c-peptide and glucose in obese women. 52 healthy women were included in this study and were allocated into three groups: 1) Placebo EA group (n = 15; mean age = 41.8 +/- 4.6 and mean body mass index {BMI} = 33.2 +/- 3.5); 2) EA group (n = 20; mean age = 42.1 +/- 4.4 and BMI = 35.9 +/- 3.6) and 3) Diet restriction group (n = 20; mean age = 42.9 +/- 4.3 and BMI = 34.7 +/- 2.7). EA was applied to the ear points Hunger and Shen Men on alternating days and to the body points LI 4, LI 11, St 36 and St 44 once a day for 30 minutes over 20 days. Diet restriction that entailed a 1450 kilocalorie (kcal) diet program was applied to the three groups for 20 days. An increase in weight loss was observed when weight loss in the EA group (p < 0.000) was compared to that in the diet restricted and placebo EA groups using the Tukey HSD test. There were increases in the serum insulin (p < 0.001) and c-peptide levels (p < 0.000) in the women treated with EA compared to those in the women treated with the placebo EA and diet restriction groups. A decrease was observed in the glucose levels (p < 0.01) in both the EA and diet restriction groups compared to those in the placebo EA group. Our results suggest that EA therapy is an effective method in treating obesity. EA therapy also helps serum glucose levels to decrease through the increase of serum insulin and c-peptide levels.
