A multi-chamber module for use in the insemination of oocytes comprises a first chamber (36) for holding a fluid medium, a second chamber (54) for receiving semen, and a third chamber (52) into which the fluid medium is arranged to flow from the first chamber (36) and from which that fluid medium passes into the second chamber (54), thereby to permit sperm to move against the fluid flow and pass by capillary flow from the second chamber (54) into the third chamber (52) where the insemination takes place. The capillary flow is established in radial passages (51) between the confronting surfaces of cup-shaped containers (24) and 40). A waste chamber (38) surrounds the second chamber (54).
