A lot of couples have a hard time getting pregnant and having a baby. Researchers say it could come down to an organ you might not expect - your thyroid. "This is where the thyroid is located - in the neck,” explains endocrinologist Dr. Claud Lardinois who is an emeritus professor at the University of Nevada’s School of Medicine.

The thyroid is a major regulator of the body. Dr. Lardinois says Hashimoto's disease is an autoimmune condition where the body attacks its own thyroid gland and about 10% of women have this.      

Even though their thyroid function may seem normal during pregnancy, their body could be silently attacking their thyroid.

Dr. Lardinois says the antibodies could endanger the life of the baby, which is why he believes thyroid issues need to be addressed before you even think about getting pregnant. He recommends all women - who are of child-bearing age – be tested for the Thyroperoxidase antibody (TPO). "Studies have consistently shown that women who are antibody positive have a higher risk of miscarriage."

If you are positive and your thyroid hormone is elevated - then medication early in your pregnancy might be advised. 

Studies involving more than 12,000 women found that thyroid antibodies increased the risk of miscarriage by almost 300%.
