Levator Ani & Wet Prostate Weight Assay AR Agonist Assay:

The activity of compounds of the present invention as AR agonists was investigated in an immature male rat model, a recognized test of anabolic effects in muscle and sustaining effects in sex organs for a given compound, as described in L. G. Hershberger et al., Proc. Soc. Expt. Biol. Med., 83, 175 (1953); B. L. Beyler et al, “Methods for evaluating anabolic and catabolic agents in laboratory animals”, J. Amer. Med. Women's Ass., 23, 708 (1968); H. Fukuda et al., “Investigations of the levator ani muscle as an anabolic steroid assay”, Nago Dai. Yak. Ken. Nem. 14, 84 (1966) the disclosures of which are herein incorporated by reference.
