Bruce - here is my interpretation. Akins was trying to distinguish a violent act from other genres of rape (e.g., consensual statutory rape, feigned rape to account for illicit or unintneded pregnancy, etc.). His point was going to the effects of stress on the body and its reactions. For example, the body has built-in mechanisims to deal with stress. Too much heat results in perspiration. Too much cold and the body redirects blood flow from the extemities to the organs. Too little food, metabolism slows down. In this context, it would not be unreasonable to at least raise the possibility that a female body under extreme stress, such as in the case of a violent rape, might resist getting pregnant (continued below).
