What Exactly is Testosterone?


Testosterone is a member of the steroid family of hormones called
androgens.

More and more, this family is derived through chemical
conversion from the steroid ring-structure of cholesterol. This
hormone plays a vital role in the bodies of both men and
women.There are only minor differences between this hormone and
others such as estrogen, progesterone, DHEA, cortisone, and
androstenedione. They are small molecules, which becomes important
when we look at what routes of administration are available.

As
commonly known, testosterone stimulates the development of the
penis and testes, growth of facial and pubic hair, deepening of the
voice, changes in body shape, growth of bones, and increased muscle
mass and strength in males. It helps maintain sex drive and the
production of sperm cells, and it may play a role in balding. Mood
is also affected by testosterone, and low levels of the hormone can
cause severe and prolonged depression as well as fatigue, to name a
few conditions. High levels of testosterone appear to promote good
health in men, for example,
lowering the risks of high blood pressure and heart attacks.


High testosterone levels also correlate with risky behavior,
however, including increased aggressiveness and sometimes even
smoking, which may cancel out these useful health benefits.
Ninety-five percent of circulating testosterone is produced in
the male testicles under the influence of a hormone released
from the pituitary gland called luteinizing hormone (LH).
Throughout the day, LH is released in spurts that stimulate the
release of testosterone from the testicles. The signals are
particularly strong in the early morning, which accounts for the
higher testosterone levels and spontaneous morning erections and
increased libido.

By the late evening the levels of testosterone
can fall by 50-percent, which signals the pituitary gland to
increase its production of LH to restart the
cycle.Testosterone Info provides detailed
