The American Journal of Obstetrics and Gynecology (ACOG) Committee Opinion on Hormone Therapy in Primary Ovarian Insufficiency (Specifies Recommended Hormone Dosages)

The American Journal of Obstetrics and Gynecology (ACOG) Committee Opinion on Primary Ovarian Insufficiency in Adolescents and Young Women

The North American Menopause Society (NAMS) Hormone Therapy Position Statement

The European Society of Human Reproduction and Embryology (ESHRE) Guideline on the Management of Premature Ovarian Insufficiency
