Starting from the clinical case of a high level sportive adolescent girl (in archery) not presenting any pathological structured organization, the author analyzes the processes through which the ego ideal is rehandled. Such processes are stressed through the analysis of the symptom of counter‑achievement and relation difficulties of the adolescent girl. The stress is put on the loss trial (symbolical castration) imposed by the rehandlings of the ego ideal : a giving up of childhood ego ideal and parental dependence going along with it. The castration anxiety thus shifted onto the sportive competition (to win/to lose) offers a metaphorical prop to the expression of the conflict and the material wherefrom one is compelled to deal with the psychical difficulty.
