The specific guidance mechanisms occurring in response to chemical substances (often via Ca2+ controlled asymmetry of beating) or using guides developed in various species because of special structures or tissues as well as by eggs in the vicinity of a unique entrance point on egg surface, the micropyle present in some species, are explored in this chapter. In order to avoid an excess of overlap with other chapters, several situations are described either, in the case of "simple spermatozoa" in species with external fertilisation. Part of this review chapter presents a tentative synthesis of the distribution of chemotaxis during the course of evolution.
