The increasing rate of infertility among men could partly be as a result of
stress in
jobs and other spheres of life engaged in by the men, a new health research report has shown.
In
Nigeria, for example, there are no adequate statistics of men suffering
from infertility, but experts have constantly raised concerns about a
growing rate of the challenge in the country.
These concerns have
resulted in the proliferation of herbal remedies in the form of drugs
and other aphrodisiacs advertised and sold locally along streets in the
country.
The new study shows that stress, apart from resulting in
health problems, including heart disease, asthma, obesity and
depression, can also reduce sperm and semen quality, thus affecting the
male fertility.
In the study carried out by
researchers
from the Mailman School of Public Health, Columbia University, New
York, and Rutgers School of Public Health in Piscataway, New Jersey, and
published in the journal of Fertility and Sterility, they discovered
that 'stressful life events' including a level of unemployment can cause
infertility in men.
The researchers, who studied 193 men between
the ages of 38 to 49, said their finding, after filling a form and
providing semen samples, showed that two or
more stressful life events in the past year had lower sperm quality than men who did not experience any stressful life events.
