Abstract: A sperm sorting device suitable for selectively isolating a plurality of motile sperms from a semen specimen includes a base whose bottom wall and surrounding wall define a receiving space, and a sorter securely coupled to the base and including a mounting member and a sorting filter. The mounting member has a sleeve located in the receiving space and an injection portion located at the bottom end of the sleeve and having an injection hole. The sorting filter is fixed on the sleeve and, together with the injection portion and the sleeve, defines a sorting chamber with an open top end. The sorting filter, the bottom wall, and the surrounding wall define a specimen chamber for receiving the semen specimen. The injection hole brings the specimen chamber and the sorting chamber into communication vertically, so the semen specimen can be injected through the injection hole into the specimen chamber rapidly.
