Progesterone is a female sex hormone produced mainly in the ovaries following ovulation each month. It's a crucial part of the menstrual cycle and supports fertility and a healthy pregnancy. Changing progesterone levels can contribute to abnormal menstrual periods and menopausal symptoms. Although changes in hormone levels are a natural part of life, alterations in progesterone can manifest themselves in many difficult to identify ways. Testing for low progesterone can help you address irritability, stress, sleep disturbances, and brain fog.
