17520051 Owens W, Gray LE, Zeiger E, Walker M, Yamasaki K, Ashby J, Jacob E: The OECD program to validate the rat Hershberger bioassay to screen compounds for in vivo androgen and antiandrogen responses: phase 2 dose-response studies. Environ Health Perspect. 2007 May;115(5):671-8. Epub 2007 Jan 17.

DESIGN: The Hershberger bioassay is designed to identify suspected androgens and antiandrogens based on changes in the weights of five androgen-responsive tissues (ventral prostate, paired seminal vesicles and coagulating glands, the levator ani and bulbocavernosus muscles, the glans penis, and paired Cowper's or bulbourethral glands).
Protocol sensitivity and reproducibility were tested using two androgen agonists (17alpha-methyl testosterone and 17beta-trenbolone), four antagonists [procymi-done, vinclozolin, linuron, and 1,1-dichoro-2,2-bis-(p-chlorophenyl) ethylene (p,p'-DDE)], and a 5alpha-reductase inhibitor (finasteride).

Flutamide significantly inhibited the TP-induced re-growth of seminal vesicles, ventral prostate, and Levator ani plus bulbocavernosus muscles (LABC) at 1mg/kg per day and above, and Cowper's glands and glans penis at 5mg/kg per day and above.

Procymidone is a dicarboximide fungicide structurally related to the well-characterized fungicide vinclozolin.
Male offspring exhibited shortened anogenital distance (at 25 mg kg-1 day-1 and above), permanent nipples, reduced weight of several androgen-dependent tissues (levator ani and bulbocavernosus muscles, prostate, seminal vesicles, Cowper's gland and glans penis), and malformations (hypospadias, cleft phallus, exposed os penis, vaginal pouch, hydronephrosis, occasional hydroureter, epididymal granulomas, and ectopic, undescended testes).
