Prostaglandin E2 and Your Life

Prostaglandin E2 and Your Life (revising)

Prostaglandin E2

http://en.wikipedia.org/wiki/Prostaglandin_E2#mediaviewer/File:Prostaglandin_E2.svg

Although Prostaglandin E2 starts your life by allowing a sperm to fertilize an egg (disabling the egg immunity), lets you get out of the uterus (uterine ripping for childbirth) and grows your body (stimulating your cell, brain, memory, and bone growth), it can end your life with infection, inflammation, fever, immune disorders and cancers. During your puberty, it lets you experience growing pains. After you pass puberty, you should reduce/adjust your cellular prostaglandin E2 release, so that it won’t activate cancerous DNA for you.

Stress neurohormones norepinephrine and epinephrine can induce prostaglandin E2 release via stimulation of α1– and α2-noradrenergic receptors. It produces sympathetic nervous fire (火氣) in the brain and internal organs. It acts a warning sign of over-heating or excessive stress for your body.  The most common sign is gum inflammation or oral bad smell (liver and lungs overheating).

Prostaglandin E2 heats up the central brain temperature for fever.

During sexual arousal, prostaglandin E2 gives you sex headaches, interstitial cystitis (ic) symptoms,  unwanted discharge from the penis or the vagina, yeast infection, pain and inflammation in sex organs, premature orgasm, semen leakage and premature ejaculation.
