Male Sex Act Big Picture

The male sex act begins with sexual stimulation. Somatic sensory nerves relay this information to the central nervous system. Parasympathetic impulses from the S2-S4 levels of the spinal cord cause blood to flow into the erectile tissue of the penis, resulting in penile erection. Sympathetic impulses from the T10-L2 spinal cord levels cause seminal fluids to mix with the sperm in the urethra in a process called emission. Ejaculation is the expulsion of the semen from the penis, which is caused by sympathetic innervation as well.
