Diagnosing Thyroid Disorders during Infertility Treatment

Fertility is highly dependent on several factors, including the levels of thyroid hormones. Low and high levels can affect not only the female reproductive system but also male fertility as T3 and T4 is directly linked to sperm production.

Hyperthyroidism & Fertility

While research is still ongoing to pinpoint the reason hyperthyroidism has an adverse effect on fertility, the focus is on the excessive hormone levels and the ovaries in women. Overactive levels can cause issues in the regulation of the health of the placental, uterine, and ovarian tissues.Hyperthyroidism in men can impair the volume of semen as well as the density of the sperm. The size, shape, and motility of the sperm is highly dependent on regulation of thyroid hormone levels.

Hypothyroidism & Fertility

Hypothyroidism affects female fertility by directly interrupting the menstrual cycle which can
lead to conception problems. During ovulation, the egg is not properly released from the ovaries due to low levels of thyroid hormones.Hypothyroidism can also cause male infertility because it is linked to irregular sperm morphology, erectile dysfunction, and low sexual desire. For a successful implantation, the movement of the sperm is just as important as the structure which is negatively affected with hypothyroidism.
