Common Causes of Male Infertility

[Jerald Mitchell]

Male infertility is a problem that plagues many men in the U.S. Male
infertility accounts for about 50% of infertility problems that
couples experience, and can be extremely frustrating. Unlike female
infertility, which is often times due to a disorder, male infertility
is often times linked to physical activities that limit their
reproductive abilities, or to the quality of a man's sperm.
There are two main categories of causes for male infertility: pre-
testicular, which refers to problems caused outside of the male
reproductive system, such as physical injury; and testicular causes,
which refers to sperm quality or disorders within the testes.
Pre-Testicular Causes of Male Infertility
Hypogonadism is the most common cause of male infertility in
pretesticular cases. Hypogonadism is a defect in the reproductive
system that renders the testes useless for the purposes of
reproduction. A lack of hormones leads to defective, little or no
sperm, which leads to an infertility problem. Hypogonadism is not
reversible, but there are treatments to help increase the hormone
levels and in turn, increase the chances for fertility.
Prescription and illicit drug use, along with excessive consumption of
alcohol, is another common cause of male infertility. Drug and alcohol
use is well known to decrease the amount or the quality of a man's
sperm, which can lead to problems with conceiving, or congenital
defects in the child in the event of a successful conception.
Strenuous physical activity, such as horseback riding, bicycle riding,
and other activities of the same nature, are also known to cause an
increase in fertility problems.
Testicular Causes of Male Infertility
Testicular causes of male infertility refer to disorders or problems
that happen within the tests. The most common testicular problems
include bad semen quality, which can be a genetic disorder or a result
of an unhealthy lifestyle or abnormal sperm morphology, which is
another disorder that directly affects the sperm.
Oligospermia and Azoospermia are two of the most common disorders that
lead to testicular causes of male infertility. Oligospermia is a
disorder that leaves the male with an unusually low sperm count,
making conception extremely difficult or impossible. Oligospermia can
be temporary or permanent. Azoospermia refers to the complete lack of
sperm in semen, which can be a genetic disorder, or often times is due
to scar tissue in the testes left behind from traumatic injury. While
neither of these conditions are reversible, some individuals with
Oligospermia have been treated with medications that have increased
the amount of sperm in their semen, making conception possible.
