Thyroid Hormones Can Affect Fertility

Having low thyroid (hypothyroidism), or even suboptimal levels of thyroid hormones can lead to a myriad of issues. Some of the most common ones include menstrual abnormalities in women, and a loss of libido in men. Women with mild forms of hypothyroidism may have prolonged or heavy menstrual bleeding, as well as a shorter menstrual cycle. Because thyroid hormones interact and directly affect estrogen, progesterone, and cortisol, infertility is often the result of the imbalanced endocrine system. In some women, even if pregnancy does occur, low thyroid can lead to miscarriages, or premature deliveries. Make sure to have your thyroid levels checked as part of your fertility diagnostic workup.
