Insufficient production of thyroid hormone is associated with infertility in females of child bearing age by interfering with ovulation.
Low thyroid levels in pregnant women may increase the risk of miscarriage, premature delivery, anemia, postpartum hemorrhage, and pre-eclampsia, which is a condition that causes a significant rise in an expectant mother's blood pressure during the last three months of pregnancy.
Insufficient thyroid hormone after delivery is also an underlying cause of post-partum depression, which may bring feelings of inadequacy and extreme tiredness.
