Dec 21, 2016: Low thyroid functioning may be directly linked to negative impact on women’s reproductive health, say medical experts. According to them, hypothyroidism–when the thyroid gland doesn’t produce enough thyroid hormone–is more common a cause for infertility and miscarriage in women than most of them realize.
“Thyroid disorders are very common during pregnancy. Over 25 per cent women develop hypothyroidism during the 6th week. Secretion of thyroid hormone is important for both placental and foetal development and the level needs to increase by 50 per cent during pregnancy to accommodate the increased metabolic needs of both mother and foetus,” said Arvind Vaid, IVF Expert at Indira IVF Hospitals.
He said: “When a mother’s body fails to secrete enough of it against the demand, the risk of miscarriage, pre-term birth, low birth weight, and postnatal developmental issues become higher.”
According to the experts, the thyroid is a key link to complete body wellness. When thyroid gland does not produce enough hormones; it interferes with the release of egg from ovaries during ovulation and impairs fertility.
“Conception is more difficult for hypothyroid women due to associated ovarian dysfunction. Women with thyroid disorders often have menstrual cycle abnormalities such as flooding, scanty periods or irregular cycles,” said Nagpur-based infertility expert Mayuri Assudani.
According to her, a negative feedback loop exists between the ovarian and the thyroid hormones which are needed for egg follicle maturation and ovarian production of estrogen and progesterone.
