Endocrine disorders occur when there are too many or too few hormones in the blood. Both men and women can be affected by an imbalance of the hormones insulin, steroids, growth hormone, and adrenaline. Females may experience an imbalance of estrogen and progesterone, while men may experience an imbalance of testosterone.
