It hаs been estimаted thаt between 1945 and 1971, as many as 2 milliоn children were bоrn tо mothers treated with diethylstilbestrol (DES), a nonsteroidal estrogen recommended for pregnancy maintenance. The FDA banned this drug in 1971 because research indicated a link with the incidence of cervical cancer. The article "Effects of Prenatal Exposure to Diethylstilbestrol (DES) on Hemispheric Laterality and Spatial Ability in Human Males" (Hormones and Behavior, 1992: 62-75) discussed a study in which 10 males exposed to DES, and their unexposed brothers, underwent various tests. Summary data on the results of a spatial ability test are the mean difference between the exposed and unexposed males of 1.1 units, and standard deviation of the difference of 0.5 units. Test at level .05 to see whether exposure is associated with reduced spatial ability in males.
