Intracytoplasmic sperm injection (ICSI)

Getting Pregnant

Intracytoplasmic sperm injection (ICSI)

Intracytoplasmic sperm injection (ICSI) is a fertility method in which sperm is directly injected into a mature egg to achieve fertilization. It’s a special form of IVF that solves some of the problems encountered in traditional IVF.

Reasons to do ICSI​
While IVF relies on the sperm’s ability to penetrate the egg for fertilization to occur, an ICSI procedure injects the sperm directly into the egg. This increases the fertilization rate by as much as 80%, which is why parents often move on to ICSI when traditional IVF fails. Also, ICSI is particularly recommended if the father has an extremely low sperm count or poor sperm health.

Process of ICSI
ICSI is the same as IVF except for the fertilization part where sperm gets help in penetrating the egg for fertilization. Here are the steps of an ICSI cycle

Risks
ICSI has similar risks as IVF, but because it’s a more individualized method, there are a few more risks you should know:

Benefits
Added benefits of this targeted fertility method include:

Success rate by age per cycle (estimates):

Because ICSI is part of IVF, their success rates are closely tied. However, ICSI increases the chances of the sperm fertilizing the egg. So, IVF sessions that previously yielded low embryos from implantation, can have a higher success rate with the help of ICSI. Studies have shown that doing 3 cycles of IVF increases the chances of a successful pregnancy to 50%.
