From the results reported by previous pap e rs of this series, it seems that the accessory organs of phallus (rudimentary copulatory organ) of the cock correspond to the accessory reproductive glands of the mammal in respect of the physiological functions of them. In order to investigate t he response of the androgen to the accessory organs of phallus, daily dose of 0.5-5 mg. of testosterone acetate (total dosage, 52.5 mg.) was injected for 25 days with oestrone benzoate, the amount of this being about one thirtieth of testosterone acetate, into three adult capons. The degenerated accessory organs of phallus in these capons i n creased in their weight or size to those in normal cocks. These organs became functional as glands, and the transparent fluid was secreted by them and was able to be collected from these capons, by means of the abdominal massage as well as with semen collector. Thus, the influence of androgen on the accessory .organs of phallus in the fowl is quite similar to that of androgen on the accessory reproductive glands in the mammal. So, the writer believes that the accessory organs of phallus in fowls and the accessory reproductive glands in mammals are analogous organs. In this experiment, it was also recognized that the secondary sex character, sexual behavior, phallus and vas deferens of the capon restored to the state of normal cocks by androgen administration.
