The Patagonian blenny is a protandric hermaphrodite of economic importance in Chile, where basic knowledge of its life\u2010history traits remains scarce. Using individuals collected from the artisanal fishery, we estimated the proportion of females at length (P\n                    <jats:sub>F<\/jats:sub>\n                    ) for this species in Chile through histological analysis, and compared our findings with those of previous studies conducted in the southeast Pacific and southwest Atlantic. A total of 301 individuals were collected during March and from July to October 2022, of which 189 gonads were submitted to histological analysis. P\n                    <jats:sub>F<\/jats:sub>\n                    was estimated using a generalised linear model with a binomial error distribution. Histological analysis indicated that females possess a group\u2010synchronous gonadal development, whose reproductive season occurs during autumn\u2013winter. The sexual transitional phase occurs between 30 and 40\u2009cm in total length (L\n                    <jats:sub>T<\/jats:sub>\n                    ). The fitted ogive of P\n                    <jats:sub>F<\/jats:sub>\n                    did not differ significantly between macroscopic and histological methods (\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&gt;\u20090.05). However, temporal and spatial variations in P\n                    <jats:sub>F<\/jats:sub>\n                    were evident when compared to previous studies conducted on both the Pacific and Atlantic sides.
