Occurs rapidly (within few seconds) but is slowed down by various factors such as age, alcohol intake, and fatigue. Closer to orgasm, a few drops of fluid is secreted by the cowper"s gland at the tip of the penis may contain active sperm. Several arteries supply the corpus cavernosa and spongiosum must dilate (vasodilation) for an erection to occur, allowing a strong flow of blood into the corpora. At the same time, veins carrying blood away from the penis are compressed, restricting outgoing blood flow. Multiple neurotransmitters are involved in the process, especially nitric oxide (no)
