ICSI

ICSI

ICSI is one of the most widely recognized and successful treatments for male infertility. Intracytoplasmic Sperm Infusion (ICSI) includes the immediate infusion of sperm into eggs got from in vitro fertilization (IVF).

Why Is ICSI Needed?

To be able to fertilize a woman’s egg, the head of the sperm has to attach to the outside layer of the egg. When stuck, the sperm pushes through the external layer to within the egg (cytoplasm), where fertilization happens.

In some cases, the sperm can’t infiltrate the external layer, for different kind of reasons. The egg’s external layer might be thick or difficult to infiltrate or the sperm ability to swim otherwise called motility may be low. In such cases, a technique called intracytoplasmic sperm infusion (ICSI) can possibly be used alongside in vitro fertilization (IVF) to help fertilize the egg. In ICSI, a single sperm is infused into the cytoplasm of the egg with a needle. Read more
