Understanding the impact of endocrine disruptor compounds (EDCs) across a wide range species is crucial, given their ubiquitous presence. Although invertebrate lack sex steroid hormone pathways, they exhibit sensitivity to EDCs, which could affect population dynamics. This study assessed reproductive endpoints and oxidative stress parameters in Eisenia fetida following exposure estradiol soy isoflavones, resembling concentrations found livestock manure. The experiment used artificial soil, as recommended by OECD guidelines (7:2:1 sand, kaolin peat). Adult specimens were randomly divided into seven groups (n = 11/replicate): one control, three (156.1, 283.4 633.8 μg/kg dry soil) isoflavones (113.0, 215.3 405.0 mg/kg concentrations. After eight weeks, samples collected for cytological, histological biochemical analysis. Offspring development was after 12 additional weeks. Higher isoflavone led lower germ cell number increased abnormalities, especially seminal vesicles ovaries. Catalase peroxidase activities significantly all treated groups. did not E. offspring. These findings highlight fetida's EDCs at tissue level, suggesting its use bioindicator assessing EDC contamination soils.
