[Kunming Zhongyan]Abnormal thyroid function is an important factor leading to infertility, and the reasons behind this phenomenon can be explained from many aspects.

“Ovarian dysfunction”

First, hypothyroidism can affect the normal function of the ovaries. Thyroid hormones play a key role in the female reproductive system, and their insufficient secretion can interfere with the secretion pattern of gonadotropin.

Although some patients may maintain normal menstrual cycles, anovulation may occur due to reduced potency of pituitary gonadotropins or the presence of anti-ovarian effects.

This anovulation phenomenon can significantly reduce the chances of conception and can lead to infertility.

"Autoimmune disorders"

Secondly, thyroid dysfunction is often associated with autoimmune diseases. Among patients with thyroid dysfunction and infertility, the proportion of thyroid antibody positivity is high, which suggests that abnormalities in the autoimmune system may play an important role in infertility.

Autoimmune disorders may attack the ovaries or other reproductive organs, causing impaired function and thus affecting fertility.
