According to a report by World Health Organisation (WHO), endometriosis affects roughly 10 percent (190 million) of the reproductive age women and girls globally.
Dr Ezekiel Mecha, an endometriosis researcher and senior lecturer at the Department of Biochemistry at the University of Nairobi, notes that endometrial tissue can also be found in other places such as the brain, lungs, intestines and the peritoneum (abdominal membrane).
