However, the levels of progesterone for the comparison subjects (24.1 nmol/liter, SD=2.6), and, indeed, for all the subjects, are clearly in the luteal range!—far above the well-established value of about 1 nmol/liter in men, in postmenopausal women, and in women in the follicular phase of the cycle (2–4). Luteal levels range from 6 to 64 nmol/liter. The research method used was gas chromatography/mass spectrometry; one was referred to a previous article by the same group (5). In that article, the mean level of progesterone in eight healthy comparison men was 7.2 nmol/ml, while the mean level of allopregnanolone was about 4 nmol/liter. The authors’ levels of these two steroids are thus inconsistent with their own previous data.
