How low is your t-test? The bottom of a man's normal total
testosterone range is about 300
nanograms per deciliter (ng/dL). The
upper limits are 1,000 to 1,200 ng/
dL. A lower-than-normal score on a
blood test can be caused by a
number of conditions, including:
Injury to the testicles
Testicular cancer or treatment for
testicular cancer
Hormonal disorders
Infection
HIV/AIDS
Chronic liver or kidney disease
Type 2 diabetes
Obesity and so.
Some medicines and genetic
conditions can also lower a man's
testosterone score. Aging does
contribute to low scores. In some
cases, the cause is unknown.
A low score does not always
translate to symptoms. Low testosterone scores
often lead to drops in bone density,
meaning that bones become more
fragile and increasingly prone to
breaks.
