Wrong. Testosterone is not produced only by testicles. It can also be
produced by the adrenal glands. You will find testosterone in the blood
of a mare. There has been much speculation that a "proud cut" gelding is
just one that is producing substantial amounts of testosterone somewhere
else in the body, thus making the horse "studdy" and is not necessarily
the result of an "incomplete" gelding operation.
