Links the autonomic divisions to male sexual response - Parasympathetic 'Points' (erection) and Sympathetic 'Shoots' (ejaculation).

The college version

Status: current, with caveats. The source library flags this one as still taught but qualified — read the safety notes on each component before relying on it.

Links the autonomic divisions to male sexual response - Parasympathetic 'Points' (erection) and Sympathetic 'Shoots' (ejaculation).

Point — Point = Parasympathetic = Erection

Parasympathetic nervous system (pelvic splanchnic nerves, S2-S4) mediates erection and female engorgement/lubrication

Parasympathetic nerves release nitric oxide (NO), activating guanylate cyclase to raise cGMP and relax corpus cavernosum smooth muscle, dilating helicine arteries and producing erection. In females, parasympathetic activity mediates clitoral engorgement and vaginal lubrication.

Physiology. Flaccidity is maintained by tonic sympathetic tone; erection requires parasympathetic NO release to override that tone. Both psychogenic and reflexogenic pathways can trigger erection.

Safety. Erectile dysfunction can be an early marker of cardiovascular disease or diabetes; assess risk factors and refer appropriately.

Shoot — Shoot = Sympathetic = Ejaculation

Sympathetic nervous system (hypogastric nerves, T10-L2) mediates emission; somatic pudendal nerve (S2-S4) performs expulsion

Ejaculation occurs in two phases: (1) emission - sympathetic contraction of the vas deferens, seminal vesicles, and prostate plus internal urethral sphincter (bladder neck) closure; and (2) expulsion - somatic (pudendal nerve, S2-S4) rhythmic contraction of the bulbospongiosus and ischiocavernosus muscles.

Physiology. If the sympathetic bladder-neck 'lock' fails, semen flows backward into the bladder - retrograde ejaculation ('dry orgasm').

Safety. Retrograde ejaculation is usually benign but affects fertility; document and discuss causes (TURP, alpha-blockers, diabetes).

Quick review

  • Point = Point = Parasympathetic = Erection — Parasympathetic nervous system (pelvic splanchnic nerves, S2-S4) mediates erection and female engorgement/lubrication
  • Shoot = Shoot = Sympathetic = Ejaculation — Sympathetic nervous system (hypogastric nerves, T10-L2) mediates emission; somatic pudendal nerve (S2-S4) performs expulsion

Eli explains

The same idea, in plain words

Explain it like I’m 10

A two-word reminder that the 'rest and relax' nervous system makes the penis point (get erect) and the 'action' nervous system makes it shoot (ejaculate) - with a big warning that real sexual function is more complicated.

Point — Point = Parasympathetic = Erection. When the 'rest and relax' system turns on, it releases a gas-like chemical (nitric oxide) that tells the spongy tubes in the penis to relax and open, letting blood rush in and fill them - that's what makes it stand up ('point').

Shoot — Shoot = Sympathetic = Ejaculation. When the 'action' system turns on, it squeezes the sperm and fluids along their tubes and out the end ('shoot'), while a back door (the bladder neck) locks shut so the fluid only goes forward.
