Intracytoplasmic sperm injection is abbreviated to ICSI (it is the injection of a single sperm into an egg with the help of a microscope).
In ICSI, one single sperm cell is selected and injected directly into the ovaries’ cytoplasm. This is performed with a special microscope. Essentially, this is how the micro insemination process differs from normal IVF treatment.
An ICSI procedure is applied when:
- Quality of the sperm is very poor;
- Morphology of the sperm cells is poor;
- High level of immune infertility – insemination of the ovaries was unsuccessful in a previous IVF.
