Progesterone is produced in the ovaries and the adrenal glands. When a woman gets pregnant, it begins to be produced by the placenta too. Progesterone hormone helps in preparing the body for pregnancy and conception. When not pregnant, it helps in regulating the menstrual cycle. Not producing enough progesterone can cause difficulty getting or staying pregnant. Progesterone levels fluctuate throughout your menstrual cycle.
