An IMS symposium was held at the recent Colegio Mexicano de Especialistas en Ginecología y Obstetricia held in Mexico City on 13th March, and hosted by the COMEGO President, Cuauhtémoc Celis González. The symposium focused on the Fundamentals of Menopausal Medicine. This 90-minute plenary symposium was uniquely held in English and Spanish, with two Board members and another IMS member as speakers, and with simultaneous translation available to audience members. Chair and speaker Victor Henderson spoke on the theme of Cognitive impairment: menopause or aging?. Peter Chedraui discussed Menopause and metabolic disorders and Julio Morfín Martín posed the questions ‘Menopausal Hormone Therapy: why not? why you?. The symposium was very well received by the estimated audience of 500 delegates, who participated in the Q&A session.
