In one case, the left oviduct is 8.26cm and that of the right oviduct is 7.18cm in length respectively at the experimental time but the anterior parts of the bilateral oviducts are shaped the blind non-convoluted tubes. In another case, the left oviduct is 15.20cm and that of the right oviduct is 9.21cm in length at the experimental time respectively and both the anterior parts of the two oviducts are opening. The anterior parts of the left oviducts forms the normal infundibulum and is fairly functional but that of the right oviduct slightly no more than open. In the former, one ovary which was follicular
dark yellowish-brown thin flat was present. On the other hand, in the latter two ovaries which were dark yellowish-brown thin flat were present in the normal position. But both of them does not functional.
