PBOO was induced by ligation of the urethra for 6 weeks. In vivo, erectile responses were monitored by evaluating ratios of intracavernosal pressure (ICP)\/mean arterial pressure (MAP). Organ\u2010bath studies were performed on corpus cavernosum (CC) strips. Penises were assessed at baseline for protein expression of neuronal nitric oxide synthase (nNOS) and Rho\u2010associated protein kinase (ROCK2) by Western blot. Immunohistochemistry and Masson trichrome staining were performed for analysis of nNOS protein levels and tissue alterations.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The ratio of ICP\/MAP was significantly decreased in obstructed rats (0.26\u2009\u00b1\u20090.043, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01) compared to sham\u2010control rats (0.64\u2009\u00b1\u20090.10), which was restored by the treatment (0.59\u2009\u00b1\u20090.14, <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01) compared with obstructed rats. Relaxation responses were significantly reduced in strips from the obstructed group.
