Question

Quizplus · Accepted Answer

Erection occurs due to the dilation of the arterioles supplying the sponge-like vascular spaces of the penis, which leads to an increase in blood flow and subsequent expansion of the penile tissue. This is mediated by the production of nitric oxide, which stimulates the production of cGMP, leading to smooth muscle relaxation in the penile arteries and trabeculae. The presence of sperm in the seminiferous tubules is not directly related to erection.
