Short Answer:
The success rate of gestational surrogacy depends on many factors — but in general, the success rate per embryo transfer is around 50-60%, and most intended parents achieve a live birth within 1-2 transfer cycles when using high-quality embryos.

1️⃣ What is Gestational Surrogacy?
Gestational surrogacy involves using an embryo created via IVF (in vitro fertilization), usually with the intended parents’ or donor’s egg and sperm, and transferring it to the uterus of a surrogate who carries the pregnancy.
2️⃣ Typical Success Rates
- Per embryo transfer: ~50-60% live birth rate
- Cumulative success after 2-3 transfers: ~75-90% chance of live birth
- With high-quality embryos and a healthy surrogate, the odds are very encouraging.
3️⃣ Factors That Impact Success
✅ Embryo quality
✅ Age of egg source (younger = better)
✅ Surrogate’s health and reproductive history
✅ Clinic experience
✅ Number of embryos transferred
4️⃣ How Many Transfers are Usually Needed?
- Many intended parents achieve success within 1 or 2 transfers.
- Some may require 3+ transfers if using lower-quality embryos or if other complications arise.
5️⃣ How Does Surrogacy Compare to IVF Alone?
Gestational surrogacy often has higher success rates than IVF in intended mothers with infertility, since the surrogate is typically selected based on excellent reproductive health.
6️⃣ Final Takeaway:
While no fertility process is 100% guaranteed, gestational surrogacy offers very high success rates — especially when using good embryos and working with an experienced clinic and surrogate agency.
For many families, it is a life-changing and highly successful path to parenthood.
