The author presents some ideas derived from observation in analysis about differing positions of Freud and Jung on perversion and about probable differences in perverse structural elements of women in contrast to men. In general perversion is understood as a defence of the self; in particular with women it is seen as a defensive way of achieving a false wholeness, a pseudo-androgyny. A case study describes the unfolding of a perverted transference. The importance of reaching the analyst and being understood by the analyst through projective identification is stressed. Quite often a sexually abusing mother seems to play an important role in generating female perversion; the implications in analysis are discussed as well as some ideas about culture and gender.
