New methods of laboratory testing for the sensitivity of the uterus to ovarian hormones.

A few investigators1)-7) have reported that abnormal sensitivity of the uterus to ovarian hormones exists among the endocrine disorders which are regarded as due to endocrinological disturbances. However, generally test measuring of hormones has been undertaken and the dosages of hormone preparations have been applied in diagnosing and treating endocrine disorders, and the problem on the sensitivity of the uterus has been nearly neglected. Abnormal sensitivity of the uterus is assumed to occur, either dependently or independently of endocrine disturbances of the sex hormones. In the present studies, the author attempted to elucidate the problem of the sensitivity of the human uterus to ovarian hormones by the author's new idea and succeeded in finding new methods of laboratory testing for a clinical diag nosis of the sensitivity of the uterus to ovarian hormones (uterus-sensitivity hereafter).
