Fertility Fact #27: Your Thyroid Can Affect Your Fertility
Could a thyroid problem be quietly interfering with your chances of getting pregnant?
The thyroid gland may be small, but thyroid hormones are involved in several processes that matter for reproductive health.
Both an underactive thyroid, known as hypothyroidism, and an overactive thyroid can affect menstrual patterns and ovulation. Thyroid problems can also affect pregnancy once conception occurs.
Some women may have obvious symptoms such as fatigue, weight changes, feeling unusually cold or hot, changes in heart rate, or menstrual irregularities. Others may have few noticeable symptoms.
This is why fertility assessment should sometimes include thyroid evaluation, particularly when there are symptoms, irregular cycles, or other clinical reasons to suspect a thyroid disorder.
If you are trying to conceive, consider these practical steps:
• Pay attention to persistent changes in your menstrual cycle.
• Tell your healthcare professional if you have symptoms suggestive of thyroid disease.
• If you have known thyroid disease, ensure it is properly managed before and during pregnancy.
• Do not start thyroid medication or supplements without appropriate testing and professional advice.
• If you have been trying to conceive without success, discuss whether thyroid testing is appropriate as part of your overall fertility assessment.
• Remember that thyroid testing is only one part of fertility evaluation. Ovulation, tubal factors, uterine factors, s***m health, age, and other factors may also need consideration.
One abnormal thyroid result does not automatically mean that thyroid disease is the reason for infertility. The result needs to be interpreted alongside your symptoms, medical history, and other investigations.
Sometimes improving fertility begins with identifying and treating a health problem that was never recognised.
