Evidence for a role of intracellular-calcium release in nitric oxide-stimulated relaxation of the rabbit corpus cavernosum
Calcium erection thapsigargin ryanodine

Erection is mediated by relaxation of the smooth muscle elements within the sinusoids of the corpus cavernosum. Although cavernosal relaxation can be mediated by a variety of mechanisms including pu...
Androgens modulate the alpha-adrenergic responsiveness of vascular smooth muscle in the corpus cavernosum
Penile erection testosterone adrenergic prazosin
