For many couples in Nigeria and the diaspora considering IVF, one question stands out:
👉 Should embryos be transferred on Day 3 or Day 5?
At St. Ives Specialist Hospital, a trusted IVF hospital in Lagos, we understand that this decision can feel overwhelming. To make it easier, let’s explore the differences and what they mean for your journey.
🌱 What Do Day 3 and Day 5 Mean in IVF?
- Day 3 Transfer (Cleavage Stage): At this point, the embryo has about 6–8 cells. It’s still very early in development, but strong enough to be placed in the uterus.
- Day 5 Transfer (Blastocyst Stage): By Day 5, the embryo has grown into a blastocyst with over 100 cells. This stage is much closer to what naturally implants in the womb.
⚖️ Day 3 vs Day 5: The Key Differences
Day 3 Transfer (Pros & Cons)
✅ Works well when fewer embryos are available.
✅ Reduces the waiting period, which helps manage anxiety.
⚠️ Lower implantation potential compared to Day 5.
⚠️ May require multiple transfers before success is achieved.
Day 5 Transfer (Pros & Cons)
✅ Higher implantation rates, as it matches the natural timeline more closely.
✅ Gives doctors the chance to select the strongest embryos.
✅ Reduces the risk of multiple pregnancies since fewer embryos are transferred.
⚠️ Some embryos may not survive to Day 5 in the lab.
⚠️ Requires advanced technology and highly skilled embryologists.
💡 What Nigerians Are Asking Right Now
