INTRODUCTION
Anthropogenic compounds have displaced the natural
compounds in our day to day life. The microorganisms
have shown magnificent capacity to adapt to new and
changing environment.
1,2
Humans and higher organisms
are still struggling to find solution to these toxic
compounds.

The natural compounds are not only
environmental friendly but also provides long and
healthy life.

The contemporaneous world man has moved from
natural products to synthetic products which come with a
prize to pay. WHO reported about the global trend,
wherein babies are seldom breast fed by their lactating
mothers. It is justified due to global shift from home
makers to the working women. Social and work pressure
on mothers makes it difficult for them to breast feed their
newborns. The consequence of this results in bottle
feeding. The question thus may arise “what’s wrong in
bottle feeding?” other than depriving the child of
essential antibodies present in colostrum.
A Galaxy of compounds has been reported all over the
world to be present in plastic bottles but the least studied
compound is Bisphenol A. Our intensive literature search
shows that there are very few published work available
on effect of Bisphenol A on biotic system especially in
developmental process. This paper is destined to reveal
all the information on various facets of Bisphenol A and
understand the metabolic mechanisms in the body during
development.
Chemical structure of Bisphenol A
Bisphenol A which is commonly denoted as BPA is an
organic compound which was first synthesized in 1891
by Aleksander Dianin, a Russian chemist. BPA has a
chemical nomenclature of 2, 2 – bis (4-hydroxyphenyl)
propane. The detrimental effects arise as BPA starts to
leach from the bottle and enters into the diet of the baby.
Although the effect of BPA in this case would be
postnatal, more serious effects are seen in pre-natal
exposure.

Post natal effects of BPA are manifested as change in
neuro-behaviour,
7,8
cognitive skills and social
behaviour,
9,10
underdeveloped reproductive system,
11-13
and deformed mammary glands.
14-18
The effects of BPA are agonistic to action of estrogens. It
alters developmental processes by blocking or inducing
different cell signalling in estrogen responsive and
sensitive tissues even at a very low dose (exposure). The
compound is capable of binding to the estrogen receptor
-α and -β and induces estrogenic activity.
19
The
significance of BPA was realized during the mid-1930s
with the discovery of its ability to act as an agonist to
estrogen in ovary ectomized (estrogen deficient) rats.
The phenomena was discovery by two biochemists
Edward Charles Dodds and William Lawson but failed to
explain the mechanism hence tried to solve this mystery
through their endocrinology background. Their discovery
was of much importance, due to the fact that isolation of
naturally occurring hormones was very difficult at that
point of time; hormone which could agonise the estrogen
can be easily duplicated hence it served as alternate
source to natural hormones. This opened a new arena of
extensive research on BPA which revealed severe
developmental effects on the foetus.

ABSTRACT
Globally anthropogenic materials have replaced natural materials. These substances which were industrially useful have
proved to be highly deleterious in recent decade. One of these compound is Bisphenol A (BPA), which is used in almost all
food cans and containers. This paper focus on little known aspects of BPA which is an endocrine disruptor on oogenesis, gene
implants, embryo development, mammary glands, prostate ,testis urethra. Exposure to even small concentrations of BPA have
shown severe impact on different stages of embryo development. The behaviour modifications as well as carcinogenic effects
are also discussed based on the studies on various animal models.
