The practise of the birthcontrol is annually increasing but the other side, according the numbers of registration, it the fact that a great many people still carry out the interruption of pregnancy.
The present paper deals with the outlines of patients who visited the out-patient-department of the obstetrics and gynecologics in Toritsu Sumida Hospital during the periods of six months from March to August in thirty-first of Showa and wanted the interruption of pregnancy ; The authors asked them as full as possible by interview whether they had carried out the birthcontrol and if not, the reason why they did not and if they did, the cause which they had failed through.
The total of patients who visited the hospital and wanted to interrupt the pregnancy artificially comes to 908 and those who did not carry out the birthcontrol formed 341 (37.56%) but one who inspite of birthcontrol became pregnancy formed 567 (62.44%).
In this 567 failures of birthcontrol, the cases which used only the Ogino's method account for 87 and further the other cases which used the Ogino's method with the utensils and the medicines together accounted for 324. That is, the failures of birthcontrol who used the Ogino's method lead th about 60%.
We became clear that in the methods of birthcontrol which were used in our country (Japan) the Ogino's method occupied a high percentage and its successes depended, to a great extent, upon the comprehension and proper practise of the Ogino's method.
In view of the facts that are mentioned above, we become clear that the problem which we must tink is that we must more concentrate our minds to assume leadership of the Ogine's method.
