Research in a sterility clinic is here reported. An attempt is made to correlate structure of the personality, family background, repressed antagonism between mother and daughter, oral deprivation in childhood, severe traumas, especially those occurring in the oral stage of development, high blood pressure, and other factors, with the common syndrome of spasm of the tubes, vaginismus, frigidity, and severe nausea and vomiting during pregnancy. The symptoms are regarded as defenses against the early intense hatred for the pregnant mother, with consequent fear of retribution.
