Note DF — Chapter XXI · SEX-HYGIENE FOR ADULTS

In their natural sexual life, men live at a loss, hence are more katabolic, i. e., the changes in consequence of their sexual activity are disruptive. Women, living at a profit, are more anabolic, i. e., the male sperma absorbed by her organs serve for constructive processes. But erethism of any kind, in both male and female, represents a katabolic crisis.
