Fertility and Pesticides

[Guest guest]

The correlation between fertility reduction and chemical environment

was discussed by this author in posts related to healing principles,

iatrogenic diseases and farming too. Fertility is related to seventh

dhatu shukra/virya. The chemical poisons reduce the fertility, a

natural mechanism brought in by creator of this world to protect the

purity and spiritual improvement of species of the world.

 

The changing trend in the emphasis of research is now changing

from "pharma sponsored research" to "research to help the humanity"

was also indicated by this author in some of his earlier postings

here.

 

On this back drop, here is some information on how pesticides affect

fertility. This proves the statement made in posts on natural farming

that "fertility of species is derived from soil fertility".

 

Common pesticide may impair female fertility

Researchers demonstrate that the pesticide methoxychlor inhibits the

expression of a gene involved in uterine development and function.

 

In utero exposure to methoxychlor (MXC), a common pesticide developed

as an alternative to dichloro-diphenyl-trichloroethane, DDT, may

impair female fertility, say researchers who have found that it

alters expression of the developmental gene Hoxa10 in uterine cells.

 

Researchers from Yale University School of Medicine in New Haven,

Connecticut, USA, explain that prenatal and postnatal MXC exposure

impairs the female reproductive system in mice and diminishes the

uterine decidual cell response, which is necessary for implantation.

 

Noting that Hoxa10 is "an essential mediator of the decidual

response," they studied the effects of MXC on Hoxa10 expression in

mice. This showed that neonatal MXC exposure caused reductions in

expression of Hoxa10 that lasted until adulthood.

 

They then studied the effects of MXC on a human uterine cell line,

and found that the chemical induced Hoxa10 expression and disrupted

protein complexes composed of estradiol, estrogen receptor, and the

HOXA10 estrogen response element.

 

In summary, "MXC has a lasting effect on the expression of a gene

required for reproductive tract development and function," the

researchers write. Its effects on gene expression are similar to

those reported for diethylstilbestrol, a synthetic estrogen that has

been linked with vaginal cancer, miscarriage, and pregnancy

complications," they point out.

the HRT effects on women who had undergone infertility treatments of

modern science and had turned to ayurveda after two to three

unsuccessful IVF cycles.
