Abstract: The method provides a hyaluronic-acid binding based technique to separate functionally competent and mature sperm. The method for extracting viable sperms from a semen sample comprises incubating functionalized HA with functionalized paramagnetic beads to obtain a plurality of HA coated paramagnetic beads. The method further comprises incubating the plurality of HA coated paramagnetic beads with the semen sample to obtain a first population and a second population of sperm. The first population comprises sperm bound to the plurality of HA coated paramagnetic beads and the second population comprises sperms not bound to the plurality of HA coated paramagnetic beads. The method comprises magnetically separating the first population from the second population and separating sperms from the plurality of HA coated paramagnetic beads in the separated first population to obtain the viable sperms.
