PICSI
Physiological Intracytoplasmic Sperm Injection
It is Physiological Intracytoplasmic Sperm Injection (PICSI). It is a
procedure of selecting the best possible sperm for based on physiological
characteristic along with good motility and morphology, before injecting
it into the egg as in normal intracytoplasmmic injection during an IVF
protocol. This procedure helps us in picking a single mature sperm for
injecting into the egg. Since it is known only a mature sperm can bind to
the oocyte complex (Hyaluronan) to fertilize the egg, It helps to increase
the chances of fertilization, implantation
Such mature sperms have fewer chromosomal abnormalities than the
immature sperms. This procedure helps us in having the additional
benefit over ICSI. This technique is possible, if the sperm count and
motility is good in the ejaculate.

This technique is superior to ICSI as it gives consistently better results than ICSI. This technique
also separates DNA fragmented sperms from normal sperms.
The Principle:-
-
Expression of protein HspA2 indicating sperm maturation.
-
Remodeling of cytoplasmic membrane, resulting in formation of
binding site on the sperm, for binding Zona pellucida of the oocyte.
