Iodine deficiency can cause infertility

Iodine is a micronutrient that is essential for the production of thyroid hormone and for the in-utero neurodevelopment. Iodine deficiency increases the chances of infertility and recurrent miscarriage by under producing the required levels of thyroid hormone.

Recent studies have shown that mild iodine deficiency is becoming an emerging problem in many developing countries. This concern is being highlighted, as iodine is found in very few food sources that include iodised salt, dairy and bread items.

Iodine deficiency & infertility

Iodine-deficient women have a low thyroid functioning, which has a negative impact on their reproductive health. Hypothyroidism is one of the most common causes of infertility and miscarriage in women than most of them realise.

Low functioning thyroid gland will not produce enough hormones thereby interfering with the release of egg from ovaries during ovulation that causes impairing fertility. Let's take a look at some ways to counter hypothyroidism:

Stop smoking: Smoking can damage thyroid hormone directly, as nicotine absorbs iodine from the body preventing the hormone secretion.

Moderate iodine intake: When it comes to iodine, think moderation.
Too little or too much iodine can increase the risk of developing hypothyroidism or goiter.

Reduce stress: Reducing stress using effective mind-body techniques can play a part in preventing thyroid disorder.

Monitor soy intake: Excessive soy isoflavones may trigger or worsen hypothyroidism, goiter or nodules.

If infertility remains a persistent problem even after hypothyroidism has been corrected, other interventions may be necessary.
