The effect of progesterone (P), estradiol benzoate (EB) plus P, and FSH on the testicular weight, macromolecular content, and incorporation of ^3H-leucine, ^3H-uridine and ^3H-thymidine into macromolecules was examined in the testes of immature chickens. Not P alone but EB plus P lowered the testicular weight, and content of protein and RNA in the tissues, whereas FSH brought about an increase in the weight, and content of the two macromolecular elements. The DNA content was not affected by any hormones used. P, EB plus P and FSH brought about a decrease in the incorporation of radioactive leucine, uridine and thymidine into the macromoleucles in the testes, with the exception of no change in the incorporation of ^3H-uridine after EB plus P treatment and ^3H-thymidine after FSH treatment. These results suggest that P, alone or in combination with estrogen, and FSH cause several changes in metabolic activity in the testes of immature chickens.
