Question

Quizplus · Accepted Answer

Erection does not involve the seminiferous tubules of the penis becoming engorged with sperm. Rather, it involves the dilation of the arterioles supplying the sponge-like vascular spaces of the penis, leading to increased blood flow and rigidity. The production of cGMP induced by nitric oxide also plays a crucial role in this process.
