Blastocyst Culture
AREAS OF SPECIALTY
Enhancing IVF Success with Advanced Embryo Development
Blastocyst culture is a specialized IVF technique where embryos are grown in the laboratory for 5 to 6 days—until they reach the blastocyst stage, which is a more developed and stable stage of embryo growth. This advanced method allows for better embryo selection, increasing the chances of successful implantation and healthy pregnancy.
At IshwaIVF, we use state-of-the-art culture systems and expert embryologists to grow and monitor embryos with utmost care, helping couples achieve higher success rates in their fertility journey.
What is a Blastocyst?
- Inner cell mass (ICM) – which develops into the babyA blastocyst is a highly developed embryo that forms about 120 hours (5 days) after fertilization. It has a fluid-filled cavity and a distinct cell structure with two types of cells:A blastocyst is a highly developed embryo that forms about 120 hours (5 days) after fertilization. It has a fluid-filled cavity and a distinct cell structure with two types of cells:
- Trophoblast cells – which later form the placenta
- Inner cell mass (ICM) – which develops into the baby
How the Process Works at IshwaIVF
- Egg Retrieval and Fertilization
Eggs are retrieved and fertilized through IVF or ICSI. - Embryo Monitoring
Embryos are observed in controlled lab environments for 5–6 days. - Blastocyst Transfer
Healthy blastocysts are selected and transferred into the uterus. - Surplus Embryos
Any extra good-quality blastocysts may be frozen for future use.
Why Choose Blastocyst Culture?
- Improved embryo selection: Only the strongest embryos grow to blastocyst stage.
- Higher implantation rate: Blastocysts are more likely to implant successfully.
- Better synchronization with the uterus: The uterine lining is more receptive at day 5.
- Reduced need for multiple embryo transfers: Often only 1 or 2 embryos are transferred, lowering the risk of multiple pregnancies.
- Helpful for Preimplantation Genetic Testing (PGT): Biopsies can be safely taken at this stage.
Benefits of Hysteroscopy
- Couples undergoing IVF for the first time
- Patients with multiple failed IVF cycles
- Those with good number of quality embryos on Day
- Women seeking single embryo transfer (SET) to avoid multiple pregnancy
- Couples undergoing embryo freezing or genetic testing
Frequently Asked Questions
1. Is blastocyst culture better than Day 3 embryo transfer?
Yes, it allows selection of stronger embryos with higher implantation potential, increasing the chances of pregnancy.
2. Does blastocyst transfer increase success rates?
Studies show significantly higher pregnancy and live birth rates with blastocyst transfers compared to Day 3 transfers.
3. Can all patients undergo blastocyst culture?
Not always. It is most beneficial for patients with multiple good-quality embryos on Day 3. Patients with fewer embryos may not benefit as much.
4. Is the risk of miscarriage reduced with blastocyst culture?
Yes, because embryos are more developed and healthier, the chances of successful implantation and sustained pregnancy are higher.
