The organs concerned with the production of gametes [sperms and ova (egg)] are called principal reproductive organs. The eggs escape from the surface of the ovary into the coelom and are directed by cilia into the oviduct and are temporarily stored in the ovisacs. Histologically, the wall of each ovary (Fig. Just in front of each testis are found attached yellowish finger-like processes. In adult frog this is the same case during the period of year other than breeding season.
