I will now attempt to test the etiological determinants suggested before in order to see whether they show the common character formulated by me. As the first etiological moment for the man, I have mentioned intentional abstinence. Abstinence consists in foregoing the specific action which results from the libido. Such foregoing may have two consequences, namely that the somatic excitement accumulates, and then, what is more important, is the fact that it becomes diverted to another route where there is more chance for discharge than through the psyche. It will then finally diminish the libido and the excitement will manifest itself subcortically as anxiety. Where the libido does not become diminished, or the somatic excitement is expended in pollutions, or where it really becomes exhausted in consequence of repulsion, everything else except anxiety neurosis is formed. In this manner abstinence leads to anxiety neurosis. But abstinence is also the active process in the second etiological group of frustrated excitement. The third case, that of the considerate coitus reservatus, acts through the fact that it disturbs the psychic preparedness for the sexual discharge by establishing beside the subjugation of the sexual affect, another distracting psychic task. Through this psychic distraction, too, the libido gradually disappears and the further course is then the same as in the case of abstinence. The anxiety in old age (climacterium of men) requires another explanation. Here the libido does not diminish, but just as in the climacterium of women, such an increase takes place in the somatic excitement that the psyche shows itself relatively insufficient for the subjugation of the same.
