Intracytoplasmic Sperm Injection (ICIS)

Who needs ICIS?

Intracytoplasmic Sperm Injection (ICIS)

Intracytoplasmic Sperm Injection (ICSI) is one of the most significant advancements in Assisted Reproductive Technology (ART). Introduced in the early 1990s, ICSI has revolutionized the treatment of male-factor infertility by providing an opportunity for fertilization even in cases where sperm quality or quantity is severely compromised.

ICSI is a specialised micromanipulation technique in which a single spermatozoon is carefully injected directly into the cytoplasm of a mature oocyte using specialised microinjection equipment.

Unlike conventional In Vitro Fertilization (IVF), where sperm and oocytes are co-incubated to allow natural fertilization processes to occur, ICSI bypasses several natural barriers to fertilization by introducing the sperm directly into the oocyte.

Indication for ICSI

ICSI is commonly recommended in the following situations:


*Severe male-factor infertility, including low sperm count, poor motility and abnormal morphology.

*Obstructive and non-obstructive azoospermia requiring surgically retrieved sperm.

*Previous fertilisation failure with conventional IVF.

*Use of frozen-thawed sperm with limited quantity or quality.

*Use of testicular or epididymal sperm.

*Certain cases involving preimplantation genetic testing (PGT), depending on clinical and laboratory indications.

At Kingswill Specialist Hospital – Advanced Fertility Centre, ICSI is performed by our experienced embryology team using advanced laboratory techniques and specialised equipment to support successful fertilization and embryo development.
