Some symptoms are more or less
common depending on when the shortage occurs. If the deficiency occurs during
puberty, a boy might not grow as tall or as muscular as his friends, and he
might not grow pubic or body hair. In a few, the breast tissue might begin to
develop, a condition called gynecomastia. In adult men, the picture looks a bit
different because they previously had normal levels that have declined or are
declining relative to what was normal for them at a younger age. As a result,
they may experience none, some or all of the following symptoms ( Eugene,1998).Lower libido (sex
drive), Erectile dysfunction, Poor concentration, Fatigue, Increased body fat,
Muscle weakness, Osteoporosis (weakness of the bones), Loss of body hair (including softening or loss
of the beard),
Depression, Hot flashes, Other mood problems.
Testosterone
promotes sexual desire and then facilitates performance, sensation and the
ultimate degree of fulfillment. Without adequate levels of testosterone, the quality of the male sex life
is adversely affected. Studies have found that men with low testosterone
routinely suffer from a decreased sex drive
due to inadequate NO (Nitric Oxide) release, genital atrophy, and impotence (Mehta et al .,2008).
