I invite you to think differently about polycystic ovary syndrome.
PCOS is not one thing. It is not one disease. PCOS is a set of symptoms. The key primary symptom is a failure to ovulate regularly. Failure to ovulate is why you are deficient in estradiol and progesterone. It’s why you have high testosterone, and why you develop secondary PCOS symptoms such as hair loss, acne, and infertility.
You cannot treat PCOS until you first ask: “Why, in your particular case, do you not ovulate?”
