Ann McLaren Memorial Lecture: Barriers and breakthrough – tackling taboos and the mysteries of menstruation
Professor Hilary Critchley, University of Edinburgh, UK 

This talk will cover:
• Why we need to talk about periods.
• Mechanisms involved in normal menstruation.
• Mechanisms involved in heavy menstrual bleeding.

Professor Hilary Critchley’s research programme focuses upon local uterine/ endometrial mechanisms involved in menstruation and abnormal uterine bleeding. Major contributions have been made to understanding the local endometrial response to withdrawal of progesterone, both physiological and pharmacological. She has co-chaired an International Agreement Process for terminologies /definitions and a classification system for abnormalities of menstrual bleeding. She is a member of the FIGO Menstrual Disorders Committee; a past-coordinator of the European Society of Human Reproduction and Embryology (ESHRE) Special Interest Group Endometriosis & Endometrium and is a past board member of the World Endometriosis Society (WES) and the Society for Endometriosis and Uterine Disorders (SEUD). Her clinical contributions have tackled the debilitating problems of heavy menstrual bleeding and taboo area of menstruation.

Professor Critchley’s expertise in the field of endometrial biology/ reproductive medicine has been nationally and internationally recognised. In 2009 she was elected to the fellowship of the Academy of Medical Sciences (UK) and in 2012 she was elected to the fellowship of the Royal Society of Edinburgh.
