About Advanced Embryology & ICSI
The embryology laboratory is the heart of an IVF programme. This is where eggs, sperm and embryos are handled, fertilised, cultured and graded. Careful laboratory work, stable conditions and experienced embryologists play a major role in how embryos develop.
What is ICSI?
Intracytoplasmic sperm injection (ICSI) is a technique in which a single healthy sperm is injected directly into a mature egg under a microscope. It is commonly advised when:
- Sperm count, movement or shape is reduced
- Sperm were retrieved surgically from the testis or epididymis
- Earlier IVF cycles showed poor or failed fertilisation
- Frozen sperm with limited numbers are being used
Laboratory steps involved
- Egg and sperm preparation: eggs are assessed for maturity and semen is processed to select good-quality sperm.
- Fertilisation: by conventional IVF or ICSI, as suited to your case.
- Embryo culture: embryos grow in controlled incubators that maintain temperature, gas levels and hygiene.
- Embryo grading: development and appearance are checked on scheduled days, commonly up to day 5 or 6 (blastocyst stage).
- Selection for transfer or freezing: the best embryos are chosen for transfer, and additional ones can be frozen with your consent.
What you should know
ICSI helps fertilisation when sperm quality is a problem, but it does not improve egg quality or guarantee pregnancy. Not every egg fertilises and not every embryo develops, which is a normal part of the process. Your team will keep you informed at each stage and explain the laboratory report in simple words.
Consultation
Bring previous semen reports, IVF records and hormone test results to your appointment so that the embryology plan can be personalised.
