It is known that after ovariotomy in the pullet the vestigal right gonad hypertrophies. In this study hatching chicks were castrated. At maturity serum of the pregnant mare was injected and the birds killed during the night hours. By this method hypertrophied testis like structures with many cells in active mitosis were secured. Special consideration is given to the chromosome complex in these sex reversed females
