Progesterone is a hormone that has powerful effects on sexual health, sleep quality and libido. Progesterone is a precursor of testosterone and helps balance estrogen. In men, low progesterone levels may cause a low sex drive, erectile dysfunction, hair loss, tiredness, weight gain, loss of bone and muscle, or depression. In women, low progesterone levels may cause irregular periods, abnormal bleeding, miscarriage, low sex drive, weight gain, or gallbladder problems. Rises in progesterone levels during the mid-luteal phase is an indicator of healthy ovulation.

Total progesterone is a measure of the total amount of progesterone hormone in the blood.

Free progesterone is a measure of unbound progesterone available to the body’s tissues.
