Glossary term · Treatment
ICSI (also: Intracytoplasmic sperm injection): ICSI is an IVF technique in which an embryologist injects one sperm directly into each mature egg to help fertilisation, usually for male-factor infertility.
ICSI, or intracytoplasmic sperm injection, is a laboratory technique used during IVF in which an embryologist injects a single sperm directly into each egg. The UK fertility regulator, the HFEA, says it is mainly used when sperm quality or quantity is a problem. The rest of the cycle is the same as standard IVF.
When might a specialist suggest ICSI?
The HFEA lists situations where doctors may suggest it:
- A very low sperm count.
- Sperm with abnormal shape or poor movement.
- Sperm that has to be collected surgically, for example after a vasectomy or because of a blockage.
- Frozen sperm of lower quality.
- Couples having embryo testing for a genetic condition.
The HFEA also says there is no evidence that ICSI helps when infertility is not related to sperm. Guidelines do not recommend it over standard IVF in those cases.
What risks are linked to ICSI?
The HFEA says ICSI carries slightly more risk than some other fertility treatments. Eggs can be damaged during preparation and injection. Sons conceived through ICSI may inherit the father’s fertility problems, especially where these are linked to the Y chromosome. The usual IVF risks also apply. Genetic counselling may be worth considering if inherited male infertility is a concern.
What should you ask a clinic in India?
- Why do you recommend ICSI rather than standard IVF in our case?
- Which semen tests do you need from home before we travel?
- If surgical sperm retrieval is needed, when and where will it happen?
- How will you record consent for ICSI under the ART (Regulation) Act 2021?
Questions people ask
Does the male partner need to travel?
Usually a fresh sample or surgical retrieval is needed during the cycle, so the clinic will often want the male partner present. Ask the clinic whether frozen sperm is an option and how the ART Act’s consent rules apply. Plan visas for both partners early.
Is ICSI regulated in India?
Yes. ICSI is an assisted reproductive technology and must be carried out at a clinic registered under the ART (Regulation) Act 2021. You can check registration on the National ART and Surrogacy Registry.
