Intra Cytoplasmic Sperm Injection (ICSI) is a type of IVF (see section on IVF). This is a procedure used in specific circumstances during in vitro fertilization.
The main reason to perform ICSI is because of a low sperm count or poor sperm morphology (shape of the sperm). Other reasons include sperm obtained by epididymal or testes aspiration or biopsy, previous failed fertilization in conventional IVF, when performing PGD (pre-implantation genetic diagnosis), to reduce transmission of HIV or to increase fertilization rates.
The embryologist will choose a single sperm cell (the best available) and inject it directly into the egg. This is done using a micromanipulation microscope. With ICSI nearly every man has the possibility to have his own biological child. Our laboratory is equipped with the newest high-magnification ICSI microscope. This helps the embryologist in selecting the best spermatozoa. High-magnification ICSI can improve clinical outcomes in couples with previous repeated conventional ICSI failures.
