title: The separation of sexual activity and reproduction in human social evolution.
abstract: In industrialized societies the progression of natural selection has been determined and in many cases superseded by social evolution. In the case of reproduction, there has been a decline and delay of childbearing without diminished sexual activity. While this has value for these societies, there are penalties associated with barren cycles. These include increases in endometriosis and breast and genital cancer. There also are associated issues regarding population movements that fill the "vacuums" left by underpopulation. These matters are of more than passing interest as we cope with unintended consequences of Man's dominance over the environment and other life forms.
