Does thyroid affect infertility?

The thyroid gland produces a hormone that helps in fetal development. The baby is unable to produce its thyroid hormone and is dependent on its mother. In addition, hormones are responsible for metabolism in the mother’s body. Excessive production of these amounts of hormones is called hyperthyroidism and insufficient production is called hypothyroidism. Both conditions can affect your pregnancy

Causes anovulation

Anovulation can be an irregular menstrual cycle or no period, irregular hormone levels cause anovulation.

Leads to miscarriage

Women with low thyroid hormone levels may experience a miscarriage or premature labor. Hypothyroidism makes your menstrual cycle and progesterone levels difficult. This does not allow the egg to attach to the uterus and thus, even if it is included, the mother is unable to provide the fetus with adequate thyroid hormone, resulting in pregnancy loss.


Hyperthyroidism (overactive thyroid) or Graves’ disease will cause irregular periods in women and men, hyperthyroidism causes low sperm count.

Prolactin level affects infertility

High prolactin levels in the blood in women can prevent ovulation from forming the hormone estrogen. Low estrogen can cause irregular periods or prevent periods altogether, low prolactin levels in men can cause erectile dysfunction and low sex drive.
