Thickness and areas of corpus cavernosum
and corpus spongiosum structures of the rat penis.
The passage of the duct through the corpus cavernosum
has important implications, suggesting that the origin of the defect must be a very early embryological event.
Postoperative histopathology revealed an infiltration of neoplastic cells in the subcutaneous tissue close to the albuginea, but not in the corpus cavernosum
penis, which was affected by chronic balanitis, worsened by the presence of myiasis; the chronic balanitis probably contributed to the palpable thickening of the body of the penis, simulating neoplastic infiltration.
Androgen regulates normal nerve function of the corpus cavernosum
and helps to maintain the health of the endothelium (Alberson et al.
Penile ultrasound revealed hematoma in the corpus cavernosum
and the diagnosis of PF was made (Figure 2).
The mean measured length of the corpus cavernosum
There is growing evidence that relaxation of the corpus cavernosum
mediated by non-adrenergic noncholinergic neurons is attributable to nitric oxide (NO) and cGMP .
Alprostadil (Caverject) is a vasodilator increasing the blood flow to the penis by relaxing the smooth muscles of the vascular structure of the corpus cavernosum
At the root of the penis are bulbs of the corpus cavernosum
, a mass of spongy tissue responsible for penile eversion (ASCHLEY, 1969).
The physiological role of androgens in penile erection: regulation of corpus cavernosum
structure and function.
25) Tumors invading corpus cavernosum
are at higher risk for presenting nodal metastases than those invading only corpus spongiosum, (26,27) and the deepest erectile tissue invaded should be clearly stated in the final pathology report.
Sildenafil citrate is a potent inhibitor of the electrolytic enzyme type V phosphodiesterase (PDE5) in the corpus cavernosum
and therefore increases the penile responses to sexual stimulation associated with erectile dysfunction (ED), which is a common complaint for the patients with hypertension and those taking antihypertensive agents.
A separate erectile compartment (corpus spongiosum) lies beneath the corpus cavernosum
and surrounds the urethra.
Reduction of intracellular Ca (2+) release may contribute to relaxation of the corpus cavernosum
, leading to erection (Williams et al.
However, it is likely that the chronic demyelination associated with neurotrophic variants of HIV would have some impact on the function of S2-S4 parasympathetic fibres, responsible for relaxation of smooth muscle in the corpus cavernosum
