Description	Parasitisation by the tapeworm Ligula intestinalis suppressed gonadal development in both genders of roach (Rutilus rutilus). Analysis of plasma sex steroids revealed substantially lower levels of 17 beta-oestradiol (E2) and 11-ketotestosterone (11-KT) in infected females as well as E2, 11-KT, and testosterone in infected males. In both, infected females and males, expression of the oestrogen dependent genes such as vitellogenin and brain-type aromatase in liver and brain was reduced. Furthermore, liver expression of oestrogen receptor 1 was reduced in infected females but not in males, whereas expression of oestrogen receptor 2a was up-regulated in both genders. Further, insulin-like growth factor 1 (IGF 1) mRNA in the liver was increased in infected females but not in males. The present results provide basic knowledge of the endocrine system in L. intestinalis-infected roach and clearly demonstrate that parasites can cause endocrine disruption in fish.
