As a result, there has been some interest in using oral progesterone to treat catamenial epilepsy, [64] as well as other menstrual cycle-related and neurosteroid-associated conditions. In addition to oral progesterone, oral pregnenolone has also been found to act as a prodrug of allopregnanolone, [65] [66] [67] though also of pregnenolone ...
Progesterone is the entry into the Δ 4 pathway, resulting in production of 17α-hydroxyprogesterone and androstenedione, precursor to testosterone and estrone. Aldosterone and corticosteroids are also derived from progesterone or its derivatives. Pregnenolone can be converted to 17α-hydroxypregnenolone by the enzyme 17α-hydroxylase .

Progesterone is used as part of hormone replacement therapy in people who have low progesterone levels, and for other reasons. For purposes of comparison with normal physiological circumstances, luteal phase levels of progesterone are 4 to 30 ng/mL, while follicular phase levels of progesterone are 0.02 to 0.9 ng/mL, menopausal levels are 0.03 to 0.3 ng/mL, and levels of progesterone in men ...
Sex differences in hormone levels may induce women to respond differently than men to nicotine. When women undergo cyclic changes or different hormonal transition phases (menopause, pregnancy, adolescence), there are changes in their progesterone levels. [ 90 ]
