Hypothyroidism, Infertility and Pregnancy

The thyroid gland is located in the neck in front of the trachea (windpipe). It is responsible for the production of specific “thyroid hormones”. These hormones are thyroxine (T4) and triiodothyronine (T3). Thyroid hormones are essential for a number of body functions. Normal, healthy individuals should not produce too much (hyperthyroidism) or too little thyroid hormone (hypothyroidism). If there is over or under production of thyroid hormone, then problems can occur.
