Intracytoplasmic Sperm Injection
What is ICSI ?
Intracytoplasmic sperm injection or the ICSI (iksee) as it is popularly called, is a technique in which a single sperm is injected into an egg to felicitate fertilization.
How ICSI can help ?
ICSI is generally used for the men whose sperm quality is not optimum to fertilize the egg naturally or by conventional IVF technique.
Fertlization can be achieved in male infertility conditions like
Severe oligozoospermia (low sperm count),
Asthenozoospermia (slow motility),
Teratozoospermia (deformed/abnormal sperms)
In some men, sperms are produced by the testes but they can not be found in semen. In such cases, the sperms can be retrieved surgically and these sperms can be used for ICSI to fertilize the eggs.
ICSI can also help couples whose sperms are otherwise normal but fail to fertilize the egg through regular IVF.
How ICSI is done ?
A sophesticated and sensitive equipment -Micromanipulator is used to perform ICSI. This equipment has two arms - one arm holds the egg and the otherone injects the sperm into the egg. Micromanipulator is fitted on a powerful microscope. A skillful ICSI practitioner carefully performs the task.
Is ICSI superior to IVF ?
ICSI is just another way to achieve fertilization out side the body. In some male infertility conditions mentioned above it could be the only method by which one can fertilize the eggs. However, the chances of pregnancy with ICSI or regular IVF are similar.
