The models used in these studies are discussed and compared among species, and, whenever possible, among populations. The actual state of knowledge within each group varies significantly.  Up now, the most detailed studied group is represented by Brachyura. Twenty four species of Grapsoidea, Ocypodoidea and Xanthoidea are reported in estuaries from São Paulo state, of which 14 were investigated particularly in relation to sexual maturity (58.3%). Only one of the three species of Anomura found in estuaries was studied. Among the Caridea, there are 13 species which sexual maturity were studied. Nevertheless, most studies provide only information about functional maturity, based on data about ovigerous females. Although there are many studies on relative growth for this group, the research was aimed at determining patterns of sexual dimorphism mainly for species with potential for freshwater aquaculture or fisheries. Based on this review, future studies must be focused on those species not studied yet and towards the integration of the different points of view to study the complex process named “sexual maturity” and its modulating factors. Moreover, as shown in this chapter, data about sexual maturity can be explored to provide information about the state of conservation of the estuarine areas, and hence, about the own populations and species of Decapoda.   Palavras chaves: maturidade morfométrica, maturidade gonadal, maturidade funcional Key words: morphometric maturity, gonad maturity, functional maturity
