In-Vitro Fertilisation with ICSI (intracytoplasmic sperm injection) is an assisted reproduction technique that allows for an egg to be fertilised by injecting it with a single spermatozoon. Once fertilised, the egg develops into a pre-embryo and it is then transferred to the uterus where it will continue to develop. Today, nearly 90% of IVF treatments are done using the ICSI technique.
Who is it recommended for?
- For ICSI (Intracytoplasmic Sperm Injection) treatment, only one spermatozoon is needed per egg, which means that this treatment is especially recommended for patients with azoospermia (lack of sperm),oligozoospermia (low concentration of sperm), asthenozoospermia (reduced motility), or teratozoospermia (presence of sperm with abnormal morphology).
- When ICSI is used in IVF treatments there is no additional cost.
What is needed to perform this technique?
- Preparing the sperm: We use certain techniques that allow us to retrieve motile spermatozoa (R.E.M. in Spanish). We select the highest quality sperm to be used in the micro injection.
- Preparing the egg: In the lab we remove the cells surrounding the egg so that it will be easier to manipulate and inject later. This also provides us with more information about the egg.
