What are the indications when a couple is advised to
undergo ICSI(Intra cytoplasmic sperm injection into the egg cells through a spl needle piercing Zona & oolemma? What do we mean by the process of sperm /
Round sperm (immature) retrieval from epididymis/ testis? What does the
abbreviation means too us??
testis 1) PESA
2) MESA, 3) TESA & 4) Micro TESE ??
Part A) What is the
evolution or History of ICSI? One junior doctor was asked to push the sperm
in subzonal space due to hard zona,. But he that in ICSI the head only is injected
). Surprisingly
the research team at
Brussels (
where Flower show is famous and I had the opportunity to be resent twice in that particular season) the oocyte accidentally
pushed the head of sperm (we know got fertilized,. This encouraged the researchers of Brussels to
abandon the
method of injecting sperm in
subzonal space
but directly at
cytoplasm of
mature oocyte,
That is
the reason the procedure is
globally
termed as cytoplasmic transfer and not subzonal transfer. :-Initially
used for used to overcome the barrier of zona pellucida because it is possible
that the zona becomes hard for sperm penetration due to its prolonged exposure
to culture media
