Fertilisation in ,: exploring the gamete cell surfaces with monoclonal antibodieses and the role of cell surface molecules in recognition and fertilisation. After dealing with the morphology of the gametes, the fertilisation assay and effects of a variety of treatments on fertilisation will be discussed briefly, since these aspects have been reviewed previously (Evans .., 1982;
