You have a thyroid receptor in every cell of your body. Meaning, it’s an integral part of healthy ovulation, implantation, and a full term pregnancy.
If you’re struggling to conceive or having recurring miscarriages, make sure you get a comprehensive thyroid panel. This is what you want tested:👇🏼
❗TSH
❗Free T3
❗Free T4
❗TPO & TGAB (to rule out Hashimoto’s)
Here’s why each one matters for fertility:
TSH – This is the signal from your brain to your thyroid. When levels are too high or too low, it can disrupt ovulation, shorten the luteal phase, and increase miscarriage risk.
Free T4 – This is the main hormone your thyroid produces. Your body must convert it into the active hormone (T3). If levels are low, your metabolism, egg quality, and hormone balance can all be affected.
Free T3 – This is the *active* thyroid hormone that your cells actually use. Low Free T3 can impact egg development, progesterone production, implantation, and overall energy needed for pregnancy.
TPO & TGAB antibodies – Many women with fertility struggles or recurrent miscarriages have thyroid antibodies- even when their TSH looks “normal.” Thyroid antibodies can increase inflammation and interfere with implantation and pregnancy maintenance.
A “normal” thyroid screen that only checks TSH often misses these underlying issues.
When the thyroid isn’t functioning optimally, the body may not feel safe enough to ovulate regularly, support implantation, or maintain a pregnancy.
The good news? When thyroid health is addressed, fertility outcomes often improve significantly!
