Human fertility and differential birth rates in American eugenics and genetics: a brief history.

Eugenics is a broad term used to describe a variety of social and state-sponsored reform movements. Although we usually think of Nazi atrocities when we hear the word "eugenics," in this article I discuss the manifestations of hereditary reform worldwide. In particular, I consider the history of eugenics in America, focusing on concerns about the differences in birth rates between various racial, ethnic, and educational groups. In the early twentieth century, the social and cultural expectations that surrounded the growing knowledge in genetics implied an ethical imperative for physicians. Physicians were expected to use their knowledge about genetics to help them decide what sort of advice and assistance should be given to those who wanted knowledge about birth control, or help in resolving problems concerning sterility and infertility. Today, with growing knowledge about human genetics, physicians are subject to increasing pressure to make similar judgments.
