Fertility can be affected by both an overactive and an underactive thyroid. But why?

The thyroid hormones, which are produced in the thyroid gland, are essential for the optimal control of all processes that can lead to pregnancy. Both sex and thyroid hormones are closely related to each other to enable a smooth pregnancy. If this sensitive hormone balance gets out of joint, egg cell maturation and the female menstrual cycle can be severely disrupted.


If you have an underactive thyroid, you will notice symptoms such as poor performance and concentration, tiredness, sensitivity to cold and slowed reflexes, as well as increased muscle cramps. Other symptoms of hypothyroidism can include weight gain, depressed mood, constipation and reduced fertility and potency.


If you have an overactive thyroid, you will notice the following changes or symptoms: restlessness, nervousness, mood swings, irritability, sleep disorders, increased thirst and sweating, weight loss, hair loss and menstrual disorders.


For a diagnosis, you should contact your family doctor or trusted gynecologist. Here you will be physically examined and the doctor will feel your thyroid gland. This allows him to determine whether the thyroid gland is enlarged or whether there are nodules. The best way to diagnose thyroid dysfunction is to have a blood test. Here the concentration of the thyroid hormones is examined. The doctor can use the values ​​to determine whether the thyroid gland is underactive or overactive.
