Dr Jasdev Singh
Blastocyst Culture
Embryos are grown in the lab for five or six days before transfer or freezing, which helps show which ones are developing well.
Genetic Testing & Advanced IVF
Growing embryos for longer to help choose which to transfer
A blastocyst is an embryo at around day five or six, when it has a fluid filled centre and two types of cells. Growing embryos to this stage, called extended culture, lets the embryologist see which ones keep developing.
Waiting those extra days can feel tense. The added time gives more information for choosing an embryo.
Dr Jasdev discusses whether blastocyst culture suits your embryo numbers and history.
A plan that starts with your results
Your age, history, test results and goals are reviewed before any treatment is suggested.
Clear reasons for each step
You will know why a test or medicine is recommended, what it can do and where its limits are.
Care that stays connected
Reviews are planned around how you respond, your cycle timing and your next decision.
What blastocyst culture can give you
- More information to help choose an embryo
- Transfer at the stage an embryo would naturally reach the womb
- Embryos that are suitable for freezing and genetic testing
How your care is planned
Every stage answers three questions: what is happening, why it matters, and what comes next. The plan is reviewed at each stage and adjusted when needed.
Fertilise the eggs after collection
Grow the embryos in the lab to day five or six
Transfer or freeze the embryos that develop well
How blastocyst culture works
After fertilisation, embryos are kept in incubators that match conditions in the body. Each day, the embryologist records how they are growing. Not every embryo reaches day five, and this is normal. Those that do can be transferred, frozen or tested.
Who may benefit
Couples with several embryos, where choosing between them matters. It is also needed for genetic testing of embryos. When there are very few embryos, an earlier transfer may sometimes be discussed instead.
What to expect
You will receive updates on how many embryos are developing. Transfer takes place on day five or six, and suitable remaining embryos are frozen. If no embryos reach the blastocyst stage, the likely reasons and next steps are explained.
How Dr Jasdev works with you
He brings together experience in fertility and gynaecology, and he explains things in plain language. Advice is based on current evidence and on what matters to you. You will always know what the next step is and why it has been suggested. He sees couples from Kuala Lumpur and across Malaysia, as well as some who travel from neighbouring countries.
What to bring to your appointment
Your records help Dr Jasdev understand your history quickly, so more of the visit can go to your questions. If you cannot find everything, bring what you have.
- Your previous embryology reports
- Questions about embryo grading and numbers
- Your plans for any extra embryos
What couples often ask
Most couples arrive with several questions. These common ones can help you plan what to ask.
Should we transfer on day three or day five?
What if no embryos reach day five?
How are blastocysts graded?
Can every blastocyst be frozen?
Your questions about blastocyst culture
What is blastocyst culture?
It is growing embryos in the lab for five or six days, to the blastocyst stage, before transfer or freezing.
Who is it suitable for?
Couples with enough embryos to benefit from extra time for selection, and anyone planning genetic testing of embryos.
What is needed before it?
An IVF or ICSI cycle in which eggs have fertilised. No separate tests are needed.
Is there any risk?
Some embryos stop growing between day three and day five. This usually reflects the embryo itself rather than the culture. You will be kept informed throughout.
Why see Dr Jasdev for this?
He explains how extended culture fits your situation and discusses the timing of transfer openly.
How do I book?
Blastocyst culture is planned as part of your IVF cycle. Call or WhatsApp the clinic to discuss it.
This page is general information and does not replace a consultation. Whether a treatment suits you, and its risks and timing, should be discussed with Dr Jasdev based on your own history.
