abstract	A fluid contg. living sperm cells which have residual positive or negative charges is treated so that cells having a certain polarity are immobilised and cells of opposite residue charge remain free and method comprises treating with an agent having an electrostatic charge of a certain polarity so that sperm cells having opposite polarity are preferentially immobilised in the fluid. Specifically claimed agents include sulphonated polystyrene polyelectrolyte, pref. (vinyl-benzene sulphonic acid sodium salt) and poly(vinylbenzyltrimethylammonium).
