What is ICSI?
ICSI is performed by embryologists using specialised microscopes. After egg retrieval, mature eggs may be injected with a selected sperm. Fertilisation is then checked, and embryos are cultured similarly to other IVF embryos.
Difference between IVF and ICSI
In conventional IVF, many sperm are placed around each egg. In ICSI, one sperm is injected into the egg. The rest of the cycle — stimulation, egg collection, embryo culture, and transfer — follows a similar overall pathway. Your specialist will explain which fertilisation method may be more suitable.
When ICSI may be recommended
ICSI may be considered in selected situations after evaluation. It is not required for every IVF cycle.
- Low sperm count, reduced motility, or abnormal morphology
- Sperm retrieved surgically
- Previous fertilisation failure with conventional IVF
- Use of frozen sperm in some cases
Male infertility and fertilisation
Male infertility is common and often first assessed with semen analysis. If sperm parameters are significantly reduced, ICSI may help eggs fertilise in the laboratory. It does not treat the underlying cause of sperm problems, and it does not guarantee a healthy pregnancy.
Embryo development and transfer
After ICSI, embryos are observed in the IVF laboratory. Suitable embryos may be transferred in the same cycle or frozen for later use, depending on medical advice. See IVF laboratory for how embryology supports this stage.
Frequently asked questions
Is ICSI only for male infertility?
ICSI is most often discussed when sperm factors are present, but your specialist may recommend it for other laboratory or clinical reasons after review.
Does ICSI guarantee fertilisation?
No. ICSI may improve the chance of fertilisation in some situations, but not every egg fertilises, and not every fertilised egg becomes a transferable embryo.
Can patients from Kadapa have ICSI in Proddatur?
Yes. ICSI is offered as part of IVF care at our Proddatur hospital for patients from Kadapa and surrounding districts.
