Progesterone is a steroid hormone produced in the ovaries and adrenal glands. Progesterone is also produced in the peripheral tissue.
Some known functions of progesterone are:
• Balances the effects of estrogen
• Functions as a precursor to other steroid hormones
• Is still needed in healthy amounts; even though the ovaries no longer produce progesterone. The adrenals of menopausal women must continue to produce progesterone to balance the effects of menopausal estrogen levels.
• Is the precursor hormone for all adrenal stress-handling hormones such as cortisol. Without progesterone you cannot make cortisol, your much needed stress hormone.
• Estrogen causes cells in the uterus and breast tissue to multiply, progesterone causes the same cells to grow up and stop multiplying, therefore, reducing the risk of cancer (cell growth out of control).
• Stimulates new bone growth
• Helps calm and focus brain function
• Is a natural muscle relaxer
• Keeps testosterone from getting too high
• May help against autoimmune diseases
