Thyroid stimulating hormone (TSH) is produced by the pituitary gland in the brain. This hormone stimulates the thyroid gland, located in the front of your neck, to produce thyroid hormones: thyroxine (T4) and triiodothyronine (T3).
Some thyroxine (T4) in your blood is bound to proteins, and some thyroxine (T4) circulates freely, or unbound from proteins. Testing for unbound thyroxine (FT4) is more accurate than testing for bound thyroxine (T4). In peripheral tissues, thyroxine (T4) is changed to triiodothyronine (T3) which is the most active thyroid hormone. These hormones control your metabolism.
The thyroid gland can overproduce (hyperthyroidism) or underproduce (hypothyroidism) thyroid hormones. Hypothyroidism and hyperthyroidism can each negatively impact fertility—both the ability to become pregnant and the ability to carry a baby to term.
