They had significant decreases in total and free levels of testosterone, during recovery following resistance activity, and anabolic hormones (total and free testosterone, and dehydroepiandrosterone sulfate) to cortisol ratios were low, during resistance exercise, which stated a less anabolic medium, paradoxically.
The patients with suppressed post DST cortisol levels were considered to have non-functional adenoma, if they additionally had at least one of the following criteria: (i) morning dehydroepiandrosterone sulfate (DHEA-S) levels[greater than or equal to]40 [micro]g/dl, (ii) non-suppressed plasma corticotrophin (normal value: [greater than or equal to]5 pg/ml) or (iii) UFC<110 [micro]g/day.

In this comparison of two oral contraceptives (OCs) containing the same progestin but different dosages of ethinyl estradiol, women using the 25-[micro] g formulation were significantly more likely to report improvement in premenstrual mood than were those using the 35-[micro] g pill, although this effect was not reflected in measures of free testosterone (FT) or dehydroepiandrosterone sulfate (DHEAS).

A serum dehydroepiandrosterone sulfate (DHEA) level below the aged-adjusted 10th percentile is a better marker for tow sexual desire and function, but the majority of women with a low DHEA level do not have sexual dysfunction.
