What IVF actually means here
IVF (in vitro fertilization) is the lab process of combining an egg and sperm outside the body to create an embryo. In surrogacy, this embryo is created using the intended parents' own egg and sperm, donor genetics, or a combination — never the surrogate's own egg.
The IVF steps that involve the surrogate
Cycle synchronization
Your cycle is aligned with the embryo's readiness using birth control pills, then estrogen.
Lining preparation
Medications build your uterine lining to the right thickness for implantation.
Embryo transfer
A short outpatient procedure placing the embryo into your uterus.
Pregnancy confirmation
Bloodwork roughly 9–14 days after transfer confirms whether implantation succeeded.
What happens before you're involved
Earlier IVF steps — egg retrieval and embryo creation — happen entirely with the intended parents (or donors), not the surrogate. By the time you're involved, a tested, ready embryo already exists.
Fresh vs. frozen embryo transfer
Most surrogacy journeys use a frozen embryo transfer (FET), where the embryo was created and frozen earlier, then thawed for your specific transfer cycle. This is more common and gives more flexibility in timing than a fresh transfer.
"You're joining the process at a very specific, well-understood point — after the embryo already exists, with a clear medical plan guiding everything that happens next."
Success rates
Embryo transfer success rates vary by embryo quality, your age, and clinic-specific factors, but gestational surrogates — who are pre-screened for optimal uterine health — often see strong success rates per transfer. Your clinic will walk you through realistic expectations specific to your cycle.
