ICSI (Intracytoplasmic Sperm Injection)
ICSI is a specialised laboratory step used within an IVF cycle. Instead of leaving eggs and sperm to fertilise on their own, an embryologist injects a single, carefully selected sperm directly into each mature egg.
When ICSI is recommended
ICSI is most often used for male-factor infertility — for example, low sperm count, poor motility, or abnormal sperm shape. It is also used when sperm has been surgically retrieved, when previous IVF cycles had unexpectedly low fertilisation, or when using frozen or limited numbers of eggs. Your specialist will advise whether ICSI is likely to improve your chances.
How ICSI differs from standard IVF
The stimulation, egg retrieval and embryo-transfer stages are the same as conventional IVF. The difference is in the laboratory: rather than mixing eggs and sperm together, the embryologist selects one healthy-looking sperm and injects it into each egg under a microscope. This gives fertilisation the best possible chance when sperm quality or numbers are a concern.
ICSI at accredited clinics in India
ICSI depends on the skill of the embryology team and the quality of the laboratory, so accreditation and experience matter. Indian fertility centres widely offer ICSI, often as an add-on to the base IVF cycle. Ask whether ICSI is included in your quoted estimate, how experienced the embryologists are, and how they select sperm for injection.
Common questions
Not automatically. ICSI is specifically helpful for male-factor infertility and certain other situations. For many couples, conventional IVF is equally effective. A specialist should advise based on your diagnosis.
ICSI is usually an added laboratory step, so it often carries an additional cost on top of the base IVF cycle. Ask for this to be itemised in your written estimate.
