Data on the reproductive biology of the genus Hippolyte are available from studies of Hippolyte inermis. These findings support the idea that these species are protandric hermaphrodites, exhibiting sex reversal. However, recent studies of this and other species, such as Hippolyte obliquimanus and Hippolyte williamsi, have not reported sex reversal and suggest a gonochoric condition. In the present study, histological analyses were conducted of the ovaries, testes, oviducts, vasa deferentia and the development of the male appendage. The results of this study show that the Hippolyte niezabitowskii population from southern Spain should also be viewed as a gonochoric species. The study found no evidence of sex reversals. These conclusions are also supported by information on the structure of the population and by the results of studies of the male appendage. The population structure involves different size distributions of males and of females. Size classes 2-14 exhibit substantial overlap. No evidence of sex reversal was obtained from the study of the male appendage.
关于 Hippolyte 属的生殖生物学的数据可从对 Hippolyte inermis 的研究中获得。这些发现支持了这些物种是性逆转的雌雄同体的观点。然而，最近对这种和其他物种（如 Hippolyte obliquimanus 和 Hippolyte williamsi）的研究并未报告性逆转，并表明存在雌雄异体的情况。在本研究中，对卵巢、睾丸、输卵管、输精管和雄性附肢的发育进行了组织学分析。这项研究的结果表明，来自西班牙南部的 Hippolyte niezabitowskii 种群也应被视为雌雄异体的物种。研究没有发现性逆转的证据。这些结论也得到了有关种群结构和雄性附肢研究结果的支持。种群结构涉及到雄性和雌性的不同大小分布。大小类别 2-14 之间存在大量重叠。从雄性附肢的研究中没有获得性逆转的证据。
