erectile function

Erectile function involves a complex process where the blood vessels, nerves, and hormones work together to produce and maintain an erection. When a man is sexually stimulated, nerves release signals that cause blood vessels in the penis to dilate, allowing increased blood flow. This causes the chambers in the penis to expand and become rigid. An erection is maintained as the blood is trapped, and it subsides when the blood flows out or stimulation stops. Healthy blood flow, nerve function, and hormonal balance are essential for normal erectile function.
