Advancing IVF Success with Day 5 Embryo Transfers
In fertility care, timing can make all the difference. At Sparsh IVF, we leverage blastocyst culture — an advanced technique that nurtures embryos to a more developed stage before transfer — to improve pregnancy outcomes and give couples the best possible start to parenthood.
By extending embryo development to Day 5 (instead of the traditional Day 2 or 3), blastocyst culture allows for better embryo selection, higher implantation rates, and often, fewer attempts to achieve success.
A blastocyst is an embryo that has developed for five or six days after fertilization. At this stage, it has formed a fluid-filled cavity and distinct cell layers that will later become the baby and placenta.
Compared to Day 2 or 3 embryos (4–8 cell stage), a Day 5 blastocyst has:
This extended culture period allows us to:
At Sparsh IVF, blastocyst culture is done using advanced lab conditions, including time-lapse monitoring and precise media systems to mimic the natural uterine environment.
Blastocyst transfer is especially beneficial for:
It is usually advised only when sufficient embryos are available on Day 3 to ensure survival till Day 5.
Embryos are created via IVF or ICSI using the best sperm and eggs available.
Embryos are checked for cell division, symmetry, and fragmentation.
Embryos that continue to divide are observed in specialized media. Using morphological scoring and time-lapse data, we assess their developmental potential.
The best-quality blastocyst is selected for transfer. Remaining viable embryos may be frozen for future use.
At Sparsh IVF, our blastocyst success rates are significantly higher, especially in patients under 35.
| Stage of Transfer | Average Implantation Rate |
|---|---|
| Day 3 Embryo | 25–35% |
| Day 5 Blastocyst | 50–60% |
Note: These rates vary based on age, egg quality, and lab expertise.
At Sparsh IVF, we use meticulous grading and digital tools to select embryos with the best potential for each patient.
While safe and widely used, blastocyst culture may not be suitable if:
In such cases, a Day 3 transfer may be advised to avoid the risk of having no transferable embryos. We always discuss options transparently based on lab progress.
Whether you’re undergoing your first IVF cycle or returning after earlier failures, blastocyst culture offers a more precise, high-success strategy that we tailor to your unique fertility profile.
Blastocyst culture is ideal for:
This flexibility allows couples to time pregnancy safely and reduce emotional and financial strain over repeated fresh cycles.
Blastocyst culture isn’t just a lab advancement — it’s a smarter way to approach IVF. At Sparsh IVF, we use this method to increase success, reduce risks, and bring science closer to your personal story.
