How can starving africans get pregnant so easily when healthy western women have trouble?

Most are not healthy. Healthy is a word defined by the person reporting on health. As a long time reproductive md, the vast majority of those who think they are healthy actually are not. People pursuing low fat, low calorie, or vegetarian diets and who exercise (aerobic) frequently actually are hurting their chances for pregnancy. Western health is in desperate shape and starving africans may be healthier overall.
