This is the second work of Helene Deutsch's study into female psychology and sexuality. The first volume of her influential work, The Psychology of Women, appeared in 1944, to be followed by the second volume a year later. When, towards the end of her life, Deutsch came to consider the relationship of The Psychology of Women to Psychoanalysis of the Sexual Functions of Women, first published almost twenty years before, she observed: "It is evident that the first publication already contains all the building stones for the latter. What was first conceived by intuition and observation of a small number of analyzed women was later supported and confirmed by thirty years of experience".
