Hypothyroidism & Fertility

How Hypothyroidism Affects Fertility

The thyroid gland produces hormones that regulate metabolism and reproductive function. Hypothyroidism — an underactive thyroid — elevates TSH and can disrupt ovulation, cause irregular periods, increase the risk of miscarriage, and interfere with implantation. Even subclinical hypothyroidism (mildly elevated TSH) can impair IVF outcomes.

Simple Treatment, Big Impact

At Iswarya Fertility, all patients are screened for thyroid disorders at their first visit. Levothyroxine therapy to normalise TSH below 2.5 mIU/L before IVF is a straightforward intervention that significantly improves pregnancy rates.
