Abstract

Four hundreds and one periclinnacteric women who are urban in Otsu and Kusatsu are investigated by questionaires on their menstrual attitudes.
The age of menarche of these women is fifteen and fourteen subordinately. These two ages occupy almost a half of the total number. The juvenilization of onset of menarche is now under our investigation. Menopause occurs mostly later than fourty-five year of age. This implies the prolongation of reproductivity.
The present paper describes the statistical analysis on the menstrual attitude of the periclimacteric women and what is our thought regarding to the prolongation of the reproductive ages.
