Habitual abortion. Two factors of increasing frequency.

This paper deals with two major uterine factors in infertility and habitual abortion that are now occurring with increasing frequency. They are Asherman's syndrome and the syndrome of the incompetent internal cervical os. By focusing on the uterus whenever a history is suggestive, it is possible to arrive swiftly at a diagnosis. A fresh approach to the problem of investigating these patients is suggested. Tests can be based on clues provided by the patient. Methods of diagnosis and treatment are discussed. If patients are evaluated with an etiology in mind, a comprehensive study and management can be planned that will save time and expense.
