The thyroid’s impact on pregnancy chances unveiled

How does the thyroid affect fertility and the chances of becoming pregnant?

Thyroid function is linked to fertility hormones such as estrogen, progesterone, and testosterone, playing a crucial role in fertility and pregnancy. The thyroid is a gland that produces hormones, primarily thyroxine or T4 and triiodothyronine or T3, which are essential for regulating metabolism and maintaining the normal functioning of various organs, including the reproductive system. Low levels of thyroid hormone, known as hypothyroidism, can interfere with the release of an egg from your ovary (ovulation), impairing fertility. Hyperthyroidism, which involves excessive thyroid hormone, can make conceiving more challenging and reduce pregnancy chances.

Thyroid function can affect fertility and pregnancy in the following ways:

Menstrual cycle and ovulation: Hypothyroidism (underactive thyroid): Insufficient thyroid hormones can disrupt the menstrual cycle, leading to irregular periods and anovulation (lack of ovulation), affecting fertility.

Hyperthyroidism (overactive thyroid): Excessive thyroid hormones can also cause irregular menstrual cycles and may lead to difficulty in conception.

Ovulatory dysfunction: Thyroid disorders can contribute to ovulatory dysfunction, making it challenging for women to conceive.
