The aim of this study is to evaluate the viability of protoscoleces in human hepatic hydatid cysts in order to determine the prevalence of their fertility and to study the association with variables typical of the host and of the parasite.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials<\/jats:title><jats:p>A cross\u2010sectional study was done in biological material (the fluid from human hepatic hydatid cysts). The viability criteria used were: ovoid form, invaginated scolices and intact calcareous corpuscles, the presence of vibrating movements, and the absence of \u201cvital\u201d staining. The cysts were grouped as univesicular cysts (UVC), multivesicular cysts (MVC) and abscessed cysts (LAHO). Fertility was defined as living protoscoleces in relation to the total number of protoscoleces. Descriptive statistics were for the calculation of the prevalence of fertility, analytical statistics for the comparison of groups, and a multivariate analysis for the examination of the association between cyst fertility and clinical variables.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 163 cysts with a median diameter of 15\u00a0cm were studied in this way. Of these lesions, 79 (48.5%) were UVC, 54 (33.1%) MVC, and 30 (18.4%) LAHO. On 99 occasions (60.7%), macroscopic communication was evident in the bile duct, and a prevalence of general fertility of 57.1% (94.4% for MVC, 53.2% for UVC, and 0% for LAHO, with a value of <jats:italic>P<\/jats:italic> &lt; 0.001). Association with location, type, and diameter of the cyst, and presence of biliary communications was verified by applying a bivariate analysis, and association between fertility and the variables of the type of the cyst and the existence of biliary communications was verified employing a multivariate analysis (<jats:italic>P<\/jats:italic> values of 0.004 and &lt; 0.001, respectively).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>The prevalence of fertility found was low. The main prevalence of fertility was observed in MVCs.
