Although the butterfly shaped thyroid gland located at the base of the neck is very small, it produces a vital hormone that regulates metabolism and influences every organ, tissue and cell in the body. Hypothyroidism is characterized by low production of thyroid hormone which if left untreated may lead to long-term complications such as heart diseases, diabetes, nerve injury and infertility. We talked to reproductive endocrinologist Dr Aimee Evyazzadeh of Egg Whisperer Enterprises and Dr Christine Maren – a board certified physician who addressed her own pregnancy complications & hypothyroidism using functional medicine – to learn about the effects of hypothyroidism & Hashimoto’s disease on fertility, its connection with PCOS & gut health, and its management using conventional and functional medicine.
