Ejaculation: a little snippet of information

| Doing some light reading of Ganong's Review of Medical Physiology
(21st edition) and noted this:
"The semen is propelled out of the urethra by contraction of the
bulbocavernosus muscle, a skeletal muscle. The spinal reflex centers
for this part of the reflex are in the upper sacral and lowest lumbar
segments of the spinal cord, and the motor pathways traverse the first
to third sacral roots and the internal pudendal nerves. Carbon
monoxide may be involved in the control of ejaculation, since HO2, the
enzyme that catalyzes its production in the nervous system (see
Chapter 4), is abundant in the pathways concerned with ejaculation,
and ejaculatory performance is diminished when the gene for HO2 is
knocked out."
Hmmm, so sucking on your car's exhaust system might increase
ejaculatory performance <g>. Not serious! Something to keep an eye on
though.

Hmmm, might explain why I usually stop my breathing as I approach
orgasm. ...Lmac
