This treatise is published by the author to complement the material found in textbooks and compends rather than to refute or replace it. There are four general divisions of the work. In the first portion von Fekete discusses the function of the sex organs, puberty, menstrual disturbances, normal and abnormal secondary sex characteristics, and the menopause. In the second he describes sex life and its disturbances, including sterility, leukorrhea and pain. The third division is devoted to pregnancy; he particularly dwells on metabolic disturbances, though blood changes and toxicoses are also discussed. The final division is a discussion on endocrine, nervous, circulatory and constitutional changes in relation to the sex organs. The work is put up economically but in clear, readable type and easy, logical diction. The section on the endocrine glands is especially praiseworthy.
