Abstract (EN): Since reproductive parameters are common endpoints in pollution monitoring, the description of the spermatogenesis of Lipophrys pholis, a recently proposed sentinel species, is of critical importance. Mature males were used to determine the annual maturation cycle, using a stereological approach. The spermatogenic cycle was classified into three stages: early spermatogenesis (May), mid spermatogenesis (September), and spawning (November and January). The testes were asynchronously arranged with various cell types observable during all seasons, although in different proportions. Gonadosomatic index and spermatozoa proportions confirmed the established reproductive season. Differences between the sampled populations and those from septentrional locations are discussed, namely the absence of "resting" and "spent" periods.
