Progesterone is produced in the ovaries. Women with regular cycles generally make adequate progesterone. Sustaining health during pregnancy, maintaining regular menstrual cycles, breast development, and preserving brain function are all roles that progesterone plays an important part in.
Lower levels of progesterone are typically found in postmenopausal women, women who have had their ovaries removed, or women who use synthetic progestins. Signs and symptoms include those found with estrogen dominance (listed on previous slide). Higher than normal levels of progesterone are a typical and the signs and symptoms can be quite benign.
