This article will mostly be not me. It is some excerpts I
found that I felt would be important information about infertility my readers
should be informed on – and may help alleviate some stress and concern of any
couples that may be struggling to have a child.
“Infertility is generally defined as the inability to
conceive a baby after 12 months of unprotected sex. Infertility affects about
15 percent of all couples.
~ Mosher and Pratt, 1991
Infertility is attributable about equally to problems in
males and females; each sex independently accounts for about 40 percent of
cases.
…20 percent of infertile couples are diagnosed as having
idiopathic infertility…this means that doctors simply don’t know what’s wrong.
Male infertility often results from sluggish sperm or a low
sperm count. Chemical pollutants might play a major role in male infertility.
Other possible causes of low sperm counts include injury to
the testicles or scrotum, infections such as mumps in adulthood, testicular
varicose veins..., undescended testes (testes descend normally at the eighth
month in the womb), endocrine disorders, drugs and even some prescription
medications.
Here are some chemical and environmental factors affecting
male infertility
Risk Factors
Effects
Lead, used in making storage batteries and paints
|
Fewer sperm, sperm that move more slowly than normal, and
more abnormally shaped sperm.
|
Ionizing radiation, found in nuclear plants and medical facilities,
and nonionizing radiation in high-voltage switchyards and communication facilities.
|
Possible damage to sperm cells and lowered fertility.
|
Anesthetic gases
|
Unexposed female partners may have higher than normal number of miscarriages.
|
Pesticides like kepone and carbon disulfide used in the manufacture
of viscose rayon and a fumigant.
|
Possible loss of sex drive, impotence abnormal sperm,
lowered sperm count.
|
Heat stress, found in foundries, smelters, bakeries, and
farm work.
|
Lowered sperm counts and sterility
|
Estrogen, used in the manufacture of oral contraceptives.
|
Possible loss of sex drive, abnormal sperm, lowered sperm counts.
|
Methylene chloride, used as a solvent in paint and strippers.
|
Possible very low sperm counts and shrunken testicles.
|
Ethylene dibromide, used as an ingredient in leaded
gasoline and as fumigant of tropical fruit for export.
|
Possible lower sperm count and workers.
