There is a growing trend of decreasing sperm counts in industrialized nations around the world. Male fertility, of course, can be affected by a number of diverse factors.
Age alone, for example, can have an impact on fertility. Recent studies have demonstrated that fertility decreases with age (Reuters, 2003). To understand male fertility and the factors
that influence it, one must regard sperm in terms of its quality. As Moline et. al. (2000) clarify, sperm can be regarded as having a quality determined in part
by such factors as "ejaculate volume, sperm motility, sperm morphology" and various functional variables. Obviously, genetics play some role in shaping sperm quality. Other factors enter into this
equation as well, however. Quite likely one of these factors is workplace exposure to contaminants. This paper will suggest an interventional strategy to bring that problem in hand.
Although males continue to produce sperm throughout their lives (unlike women who are actually born with a set number of eggs), these sperm
begin to move more slowly as a male ages (Reuters, 2003). One study reports a loss in mobility of some 0.7 percent per year with an increase from twenty-five
percent to eighty-five percent chance of abnormal motility from age twenty-two to age sixty (Reuters, 2003). Researchers can only speculate, however, as to why this is the case.
In any event, the normal aging process is not something which we could feasibly hope to intervene in order to improve future reproductive health. What, however, if something else
were at play that were causing this phenomena of decreased fertility? Numerous studies, in fact, reports exposure to environmental contaminants might be responsible.
