Fertility Issues? Sub-clinical Hypothyroidism may be causing your issue

A properly functioning thyroid is a very important aspect for fertility BUT unfortunately often missed in infertility workups. Most fertility clinics and reproductive endocrinologists check the basic markers for thyroid such as TSH but do not look at the actual thyroid hormones which are Total and Free T4 and Total and Free T3. Time and time again I hear endocrinologists tell patients that there is nothing wrong with their thyroid because their TSH is ok and completely ignore the actual thyroid hormones. This type of analysis is very incomplete and is one of the reasons that people have trouble conceiving and prone to miscarriages.
In our practice, we see so many patients that have unfortunately been struggling with infertility and have had multiple failed IVF’s and after further investigation, their thyroid proved to be an issue even though their TSH was completely normal. It is extremely sad to hear their stories and know that they didn’t have to suffer all this time as the fix is quite simple once the issue is properly identified.
If you are struggling with infertility, please be sure to test all your thyroid levels including Total T4, Free T4, Total T3, Free T3 and Reverse T3 to make sure your thyroid is truly functioning properly and is optimized. You can read more about how all these levels are related and why we can’t just look at TSH in this article.
