Emobileclinic Trending Topic: Intracytoplasmic Sperm Injection – ICSI
What is ICSI?
ICSI is an acronym for intracytoplasmic sperm injection. A fancy way of saying “inject sperm into egg”. ICSI is a very effective method to fertilize eggs in the IVF lab. Its main use is for significant male infertility cases where the male partner has poor sperm quality (motility, morphology and cell counts).
ICSI involves the use of specialized tools and equipment that enable embryologists to select and pick up individual sperm cells in a specially designed ICSI needle.
The needle is carefully advanced through the outer shell of the egg and the egg membrane – and the sperm is injected into the inner part (cytoplasm) of the egg.
This usually results in normal fertilization in about 75-85% of eggs injected with sperm.
Fertilization rates are significantly higher in IVF with ICSI procedures.
In peculiar situations where the male partner’s sperm count is extremely low or abnormal, ICSI which is an advanced variant of IVF is the treatment of choice. In ICSI a single healthy sperm is identified under a powerful microscope and injected using advanced technological practice, into the centre of the egg.
This procedure greatly increases the possibility of fertilization taking place, even when there are multiple seminal anomalies present.
For men without visible sperm in the semen, it is possible to arrange for a special technique which aims to retrieve sperm directly from the testes (PESA and TESA -Per-cutaneous and Testicular Sperm Aspiration). Retrieved sperm will then be used in ICSI cycles as described above.
