Triclocarban (TCC) is a widely used antimicrobial agent that is routinely detected in surface waters. The present study was designed to examine TCC’s efficacy and mode of action as a reproductive toxicant in fish. Reproductively mature Pimephales promelas were continuously exposed to either 1 or 5 μg TCC/L, 0.5 μg 17β-trenbolone (TRB)/L or a mixture (MIX) of 5 μg TCC and 0.5 μg TRB/L for 22 d and a variety of reproductive and endocrine-related endpoints were examined. The data set includes: -Concentrations of the test chemicals detected in water and tissues of exposed fish -Ex vivo production of testosterone and estradiol by gonad tissue placed in culture (ex vivo). -Plasma concentrations of testosterone, 17beta estradiol, and vitellogenin -Targeted gene expression measurements examining relative abundance of messenger RNA coding for enzymes involved in steroid synthesis: cholesterol side-chain cleavage (cyp11a), 17-a-hydroxylase/17,20 lyase (cyp17), aromatase (cyp19a1a), 3b-hydroxysteroid dehydrogenase (3bhsd), 11bhydroxysteroid dehydrogenase (11bhsd), and 17b-hydroxysteroid dehydrogenase (17bhsd) as well as five additional transcripts measured included steroidogenic acute regulatory protein (star), Vtg receptor (vtgr), follicle-stimulating hormone receptor (fshr), luteinizing hormone receptor (lhr), and androgen receptor (ar). -Ovarian transcriptomics data measured using a 15000 feature oligonucleotide microarray (GEO Platform Accession GPL10259). -Survival, reproduction, and morphological data. -. This dataset is associated with the following publication: Villeneuve , D., K. Jensen , J. Cavallin , E. Durhan, N. Garcia-Reyero, M. Kahl , R. Leino, E. Makynen, L. Wehmas, E. Perkins, and G.
