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 ...
