Excerpt from The Australian Medical Journal, Vol. 6: For 1884 The conclusions arrived at by Dr. Williams as to the causes of primary dysmenorrhma, or that which appears with or shortly after the advent of menstruation, are a good deal in accord with those of Vedeler. In his opinion The menstrual pain is the result of spasm of the uterus, excited by the separation and expulsion of shreds of decidua and clow, in an organ whose sensitiveness in the performance of its function is enhanced by inappreciable conditions of tissue, dependent on imperfect develop ment, often associated with others, such as anwmia. At the close of the discussion, he said that in the great majority of cases, the os externum is well formed. He did not believe that dysmenorrhoea is due to retention, and he did believe that the pain is due to spasm caused by a peripheral irritant and further he did not think that stenosis, in the great majority of cases, had anything to do with it. In the course of the discussion great diversity of opinion found expression, a good many of the speakers upholding the correctness of the mechanical theory, which, however, must now be regarded as hardly tenable.
