Passing surrogate medical screening is an exciting milestone.
But medical clearance doesn't mean embryo transfer happens the next day.
Between medical clearance and embryo transfer, several important steps still need to happen—from legal contracts and fertility clinic coordination to medications and final monitoring.
For first-time surrogates and intended parents, this part of the journey can sometimes feel confusing because much of the work happens behind the scenes.
Here's what the process may look like.
After reviewing the surrogate's medical history, pregnancy records, laboratory testing and uterine evaluation, the fertility clinic determines whether she is medically appropriate to proceed.
Once the surrogate receives medical clearance, the next major phase can begin.
However, the exact process and order may vary depending on the fertility clinic and individual journey.
Before embryo transfer, the intended parents and surrogate generally complete their gestational carrier agreement with independent legal representation.
The agreement may address topics such as:
The surrogate and intended parents should each have the opportunity to review the agreement with their own attorney.
Once the necessary agreements are completed, the attorneys can provide confirmation that the legal phase has been completed so the medical process can continue.
After the necessary clearances are in place, the fertility clinic begins coordinating the embryo transfer cycle.
The clinic may consider:
The surrogate receives instructions explaining when to begin medications and when she needs to return for monitoring.
At this stage, following the clinic's calendar carefully becomes especially important.
Depending on the protocol, medications may be used to prepare the uterine lining for embryo implantation.
A medicated frozen embryo transfer cycle may include medications such as estrogen and progesterone.
However, not every surrogate follows the same protocol.
Some clinics may use different medication schedules or a natural/modified natural cycle depending on the surrogate and the clinic's approach.
The fertility clinic determines the appropriate protocol.
Before transfer, the clinic needs to make sure the surrogate's body is responding appropriately.
Monitoring may include:
The clinic reviews these results to determine whether the uterine lining and hormone levels are appropriate for the planned transfer.
Sometimes medication doses or timing need to be adjusted.
That doesn't necessarily mean something is wrong—it can simply be part of individualizing the cycle.
Once the surrogate's cycle is ready, the clinic can finalize the transfer schedule.
Timing is important because embryo development and the surrogate's endometrial preparation need to be appropriately synchronized.
The clinic will provide specific instructions regarding medications and preparation for transfer day.
For intended parents—especially those living internationally—this is often when the journey begins to feel much more real.
Embryo transfer is usually a relatively brief fertility procedure.
Before the appointment, the surrogate may receive instructions about:
Instructions vary by clinic, so surrogates should follow their own fertility team's directions rather than general advice found online.
Some intended parents may be able to participate in the transfer appointment, while others receive updates remotely depending on clinic policies and location.
There isn't one universal timeline.
The time between medical clearance and embryo transfer can depend on:
For some journeys, the process moves relatively quickly. For others, additional coordination or testing may extend the timeline.
Rather than focusing on one exact number of weeks, it's more useful to think of this phase as:
Medical Clearance → Legal Clearance → Cycle Planning → Medications → Monitoring → Embryo Transfer
Even after a surrogate has been medically cleared, the planned transfer date can sometimes change.
Common reasons may include:
Legal paperwork isn't finished.
The medical team may need confirmation that required legal steps are complete before proceeding.
The uterine lining isn't ready.
The clinic may adjust medications or modify the cycle.
Hormone levels aren't appropriate.
Additional monitoring or a change in timing may be necessary.
Scheduling changes occur.
Clinic availability or other logistical issues can occasionally affect timing.
A delay does not automatically mean the journey is unsuccessful.
The goal is to proceed when the medical and legal pieces are properly in place.
Medical clearance is an important milestone, but additional steps such as legal clearance, cycle planning and transfer preparation generally still need to occur.
Not necessarily. Medication timing depends on the fertility clinic's protocol, legal clearance and the planned transfer cycle.
Sometimes. This depends on fertility clinic policies and individual circumstances. International intended parents may also receive updates remotely if they cannot attend.
The surrogate continues medications as directed by the fertility clinic and later completes pregnancy testing according to the clinic's schedule.
Medical clearance may feel like the finish line of surrogate screening—but it's really the beginning of the next phase.
During the weeks that follow, the surrogate, intended parents, attorneys, fertility clinic and surrogacy team coordinate the remaining steps needed for embryo transfer.
At New Grace, we help keep each part of the journey organized—from screening and legal coordination to transfer preparation and pregnancy.
The goal isn't simply to reach transfer day as quickly as possible.
It's to make sure everyone is properly prepared when transfer day arrives.
