Reproductive system is sensitive to variations in the
environments. According to medical researches, metals and chemicals in the air,
water, food and health harm fertility in many ways. The toxicants lead to
inexorable reduction in sperm count in men while women undergo worse
anovulation, loss of fetal capability and impaired implantation.
In the recent decades, the cases of infertility have
amplified. Some report says environment pollutants adversely influence the
mammalian fertility, semen quality and fertilization success rates in vitro
fertilization (IVF). Humans are often exposed to a wide range of chemicals in
their everyday environments. This deliberately impacts the fertility rate.
Infertility is said when the female is unable to conceive
even after trying unprotected sex for 1 year. Infertility is a major concern
today. We can see numerous cases of infertility these days. Even the artificial
reproduction system is wedged these days, environment pollutants being one of
the major reasons for this.
Impact of pollutants
Exposure to air pollutants such as particulate matter,
ozone, sulphur dioxide, other volatile organic compounds leads to several
health concerns, including reproductive system. These pollutants are negatively
associated with the sperm quality of male. The reduced sperm quality further
leads to less fertility.
In females, exposure to these pollutants leads to preterm
birth or decreased fecundability. It also leads to endocrine disruption and
impairing fertility.
Particular matter is one of the main pollutants that affect
air quality. Particular matter has been found to be significantly associated
with reduced fertility rates, reduced live birth and increased risk of miscarriage
in IVF.
Exposure to dioxin
Talking broadly, contamination to health hazards in the
environment causes major disorders in human reproductive system. Dioxin
exposure leads to abnormal spermiograms in male. Maternal disclosure to dioxins
is also associated with reduced fetal growth. This exposure is also associated
with other negative reproductive factors in men and women with relative
consistency.
