What Are The Causes Of Low Sperm Count?


Share |

There are many potential factors that can go into having a low sperm count.  As such, a low sperm count is the leading cause of fertility problems among men.  Some of the causes of low sperm count will go away on their own.  Some of the causes of low sperm count may be resolved medically.  In many cases, however, low sperm count may not be able to be resolved at all.

It is important, first, to understand what exactly is meant by a low sperm count.  In a “normal” sperm count, as defined by the World Health Organization (WHO for short) the concentration of sperm within semen should be at least 20 million sperm per ml of semen.  The total volume of the semen should be at least 2 ml, and therefore the total number fo sperm in the ejaculate should be at least 40 million.  Any time a man’s sperm count is below these figures, he is considered to have a low sperm count.

There are a myriad of causes of low sperm count.  One of the most common types of causes, and one which often cannot be resolved, is genetic causes.  In some cases, this could include Cystic Fibrosis, where a patient is missing or has an obstructed vas deferens (the tube that carries sperm.)  Klinefelter Syndrome is another common genetic cause.  Men who have Klinefelter system, in which they carry two X and one Y chromosome, may negatively impact the testicles and cause infertility.  Kartagener syndrome, which is a disorder in which the position of the major organs are reversed, can also cause infertility.

There are lifestyle-related factors, as well, that can be causes of low sperm count.  Stress can lead to a low sperm count by interfering with hormones.  Smoking and illicit drug use can also impair sperm count.  Nutritional deficiencies, such as selenium, zinc, foliate and Vitamin C may be risk factors for causes of a low sperm count.  Even exposure to heavy metals or toxins can cause a low sperm count.  Some studies even suggest an association between obesity and low sperm count.

Regardless of the particular causes of low sperm count, some men have had luck using traditional medical remedies for low sperm count, whereas others have tried home remedies, supplements, and other methods to increase their sperm count.
