ART (Assisted Reproductive Techniques)
In Vitro Fertilization
The ability to freeze and thaw with retention
of viability. Frozen tissue can be stored
indefinitely in liquid nitrogen at -196°C. It
stops temporary the motabolic process
without kill the cell.

Artificial insemination is a means of attaining
pregnancy not involving sexual intercourse. It
deliberates introduction of semen into
female’s vagina or oviduct for the purpose of
achieving a pregnancy through fertilisation.
In Vitro Fertilization
In vitro fertilisation (IVF) is a process by which an
egg is fertilised by sperm outside the body. The
term in vitro, from the Latin meaning in glass, is
used, because early biological experiments
involving cultivation of tissues outside the living
organism from which they came, were carried out
in glass containers such as beakers, test tubes, or
petri dishes. Today, the term in vitro is used to
refer to any biological procedure that is
performed outside the organism it would
normally be occurring.
Intracytoplasmic Sperm Injection
Intracytoplasmic sperm injection (ICSI)
involves injecting a single sperm directly into
an egg in order to fertilise it. The fertilised egg
(embryo) is then transferred to the woman’s
The major development of ICSI means that as
long as some sperm can be obtained (even in
very low numbers), fertilisation is possible.
Genome Resources Banking
Genome resource banking (GRB) is defined as the
storage of gametes and embryos from threatened
populations with a deliberate intention to use them in
a breeding program at some future occasion.
Genetic material from rare and endangered species can
be collected and preserved indefinitely in liquid
nitrogen (-196°C). These genetic samples can provide
'insurance' for the future against catastrophic events
and can potentially be a resource allowing
reintroduction of genes into a population via artificial
insemination or embryo transfer.
Nuclear transfer is the technique currently
used in the cloning. The parental nucleus were
replaced by the new one from the donor
nucleus to produce the duplicate of donor.
Superior mother produce high quality of
zygot, than implanted it in to another mother.
It allows a high production number of the
children with a high quality.
