After several unsuccessful IVF cycles or embryo transfers, intended parents often begin asking:
Should we keep trying IVF—or is it time to consider a surrogate?
There is no universal number of failed cycles that means someone “needs” gestational surrogacy.
More importantly, a surrogate does not solve every cause of IVF failure.
A gestational surrogate changes who carries the pregnancy. She does not change the quality or genetics of the embryo.
That means surrogacy is most relevant when:
Current American Society for Reproductive Medicine guidance specifically states that gestational carriers can be considered in cases of multiple unexplained IVF failures involving good-quality embryos and, in its 2026 guidance, after several failed embryo transfers.
The question is therefore not simply:
“How many times has IVF failed?”
It is:
“What part of the reproductive process appears to be preventing pregnancy or birth?”
That answer can help determine whether another IVF attempt, donor eggs, additional medical evaluation, or gestational surrogacy is the more logical next step.
IVF can be unsuccessful at several different stages.
You may have experienced:
Those outcomes are not interchangeable.
If you cannot create viable embryos, changing the person carrying the pregnancy may not solve the underlying problem.
If you have viable embryos but repeated transfers fail despite an apparently appropriate uterine evaluation, surrogacy may eventually become more relevant.
Before considering a gestational carrier, ask your reproductive endocrinologist to help identify where the process is breaking down.
Our guide to IVF Failure: Why IVF Doesn’t Work Sometimes and What to Do Next explains those different stages in more detail.
A gestational surrogate provides the uterus and carries the pregnancy.
An embryo that has already been created through IVF is transferred to her uterus.
She does not provide the egg and therefore does not contribute inherited DNA to the child.
That means changing to a gestational carrier changes the gestational environment.
It does not change:
This distinction is critical when deciding whether surrogacy addresses the problem you are actually experiencing.
If embryos repeatedly stop developing before transfer, the uterus is not yet part of the problem.
Likewise, if embryos are chromosomally abnormal because of age-related egg factors, moving those embryos to another uterus does not make them chromosomally normal.
If your primary challenge involves:
your physician may be more likely to discuss another retrieval strategy, donor eggs, donor sperm, or another approach to embryo creation.
Surrogacy becomes more relevant when you have embryos available and the concern is implantation, carrying the pregnancy, or medical safety.
ASRM identifies several established circumstances in which gestational surrogacy may be appropriate.
These include:
ASRM also says gestational surrogacy may be considered when an unidentified endometrial factor is suspected after multiple unexplained IVF failures despite transfer of good-quality embryos.
Its newer 2026 guidance on recurrent implantation failure similarly states that use of a gestational carrier may be considered after several failed embryo transfers.
That does not mean every person with multiple failed transfers should immediately move to surrogacy.
It means that after appropriate evaluation, gestational surrogacy becomes one reasonable option to discuss.
One unsuccessful embryo transfer can feel enormous emotionally.
Medically, however, it does not automatically establish that someone has an implantation disorder.
Current ASRM guidance defines recurrent implantation failure based on the cumulative expected chance of implantation after multiple good-quality embryo transfers.
For euploid embryos, the 2026 guidance notes that recurrent implantation failure may generally involve approximately three to six failed euploid embryo transfers, depending on the circumstances.
That is very different from saying:
“The first transfer failed, so my uterus cannot carry.”
Even excellent embryos do not implant every time.
This is one situation where the conversation may change.
A euploid embryo has been tested through PGT-A and found to have the expected number of chromosomes.
Euploid embryos generally have stronger implantation potential than known chromosomally abnormal embryos.
If several appropriately transferred euploid embryos fail to implant, your fertility specialist may look more closely at:
Sometimes no explanation is found.
When several good-quality embryos repeatedly fail despite appropriate evaluation, ASRM recognizes that use of a gestational carrier may be considered.
This is one of the clearest situations in which asking whether a different uterus could improve the opportunity for pregnancy becomes medically reasonable.
Repeated pregnancy loss is different from repeated implantation failure.
ASRM’s 2026 guidance defines recurrent pregnancy loss as two or more spontaneous pregnancy losses.
But recurrent pregnancy loss does not automatically mean a surrogate is the next step.
Miscarriage can involve:
If pregnancy repeatedly begins but ends because embryos are chromosomally abnormal, changing the uterus may not solve the problem.
If losses are associated with a significant uterine abnormality or another condition related to carrying the pregnancy, gestational surrogacy may become more relevant.
The cause—or suspected cause—matters.
You do not need to experience repeated IVF failure before considering surrogacy if pregnancy itself is medically unsafe.
ASRM recognizes gestational carriers as appropriate when pregnancy would pose a significant risk of harm to the intended parent or fetus.
Examples can include certain serious:
The relevant medical specialists should determine whether pregnancy is appropriate.
Surrogacy should not be framed as requiring someone to risk another dangerous pregnancy just to “prove” they cannot safely carry.
Certain uterine conditions may make implantation or maintaining pregnancy difficult.
ASRM specifically identifies significant uterine abnormalities, including examples such as irreparable Asherman syndrome and certain uterine anomalies associated with recurrent pregnancy loss, as potential indications for using a gestational carrier.
Depending on the condition, treatment may first be possible.
But when the uterus cannot be adequately corrected or carrying remains medically inappropriate, using a gestational surrogate may offer another path.
This is one of the clearest indications for gestational surrogacy.
Someone may not have a uterus because of:
If viable eggs or embryos are available, a gestational carrier can carry the pregnancy.
If eggs are also unavailable or unsuitable, donor eggs can be combined with gestational surrogacy.
Sometimes intended parents reach surrogacy only after already becoming parents.
A previous pregnancy may have involved:
Whether another pregnancy is safe is an individualized medical decision.
If your maternal-fetal medicine specialist, OB/GYN, or other physician advises that another pregnancy would create substantial risk, gestational surrogacy can allow you to pursue another child without requiring you to personally take that risk.
Not necessarily a single perfect diagnosis.
Sometimes repeated embryo transfers fail even though physicians cannot identify a clear uterine abnormality.
ASRM specifically recognizes unidentified endometrial factors as a possible reason to consider gestational surrogacy after multiple unexplained IVF failures involving good-quality embryos.
That is important because reproductive medicine does not always produce one definitive answer.
You may eventually reach a point where your physician says:
“We cannot prove exactly why these transfers are failing, but based on your history, trying a gestational carrier is reasonable.”
That can be a legitimate medical recommendation.
Repeated failed IVF cycles are exhausting.
After enough disappointment, intended parents understandably want to change something.
But a major change is only useful if it addresses the likely problem.
Imagine three families:
They repeatedly retrieve eggs but cannot create viable embryos.
Changing to a surrogate does not address the main problem.
They have several euploid embryos, but repeated well-managed transfers have failed and uterine factors are suspected.
A gestational carrier may be worth discussing.
They have healthy embryos, but pregnancy would pose a serious medical risk to the intended mother.
Surrogacy directly addresses the problem.
All three families have experienced difficulty becoming parents.
But they do not necessarily need the same solution.
Donor eggs change the egg source.
Surrogacy changes the pregnancy carrier.
If your fertility specialist believes the primary issue is:
donor eggs may address the problem more directly than changing the person carrying.
You can learn more in our guide to Using Donor Eggs to Become a Parent.
Yes.
Some intended parents face two separate barriers:
creating viable embryos and carrying a pregnancy.
For example, someone may have diminished egg quality and also have a medical condition that makes pregnancy unsafe.
In that case:
These are separate roles addressing separate challenges.
Simple Surrogacy coordinates both egg donation and gestational-surrogacy journeys for intended parents who need both.
Your fertility specialist may recommend reviewing some combination of:
The goal is not to perform every fertility test available.
The goal is to understand whether changing the gestational environment is medically logical.
There is another side to this decision.
Some patients remain in IVF treatment for years because there is always one more test or experimental add-on someone can offer.
Current ASRM guidance on recurrent implantation failure cautions that several commonly promoted interventions do not have sufficient evidence for routine use.
That includes routine use of certain receptivity testing, immune treatments, endometrial scratching, and several other proposed interventions.
You do not necessarily have to exhaust every experimental treatment before you are “allowed” to discuss surrogacy.
Ask your fertility specialist:
Is there evidence this treatment is likely to address my particular problem?
and
At what point would you personally recommend trying a gestational carrier instead?
Those are reasonable questions.
This can be harder than the medical decision.
For many women, moving to gestational surrogacy involves grieving the pregnancy experience they expected to have.
You may be grieving:
You may simultaneously feel relieved that another pregnancy will not require more injections, failed transfers, miscarriages, or medical risk.
Both emotions can exist together.
You do not have to be completely happy about losing the experience of pregnancy before you can be excited about becoming a parent through surrogacy.
Changing paths can sometimes feel like failure.
It isn’t.
There is a point at which continuing the same treatment may no longer be the best way to pursue the actual goal.
And the goal was never:
to win at IVF.
The goal was:
to build your family.
For some people, another IVF attempt is absolutely worthwhile.
For others, donor eggs make sense.
For others, gestational surrogacy becomes the more medically appropriate route.
Changing strategies does not erase everything you already went through.
It uses what you learned from those experiences to make the next decision.
Often, yes.
Many intended parents begin surrogacy with embryos already created and frozen.
That can be helpful because it separates two questions:
Do we have embryos available?
and
Who will carry the pregnancy?
Having embryos available may also simplify the later fertility-clinic process.
However, families sometimes begin exploring agencies or learning about surrogacy before embryo creation is fully complete.
There is no single required order.
Our Surrogacy Process for Intended Parents explains the overall journey.
The next stages generally include:
Learn how screening, matching, escrow, legal coordination, insurance review, and pregnancy support work.
You will provide information needed for screening and matching.
At Simple Surrogacy, the surrogate chooses first. She reviews compatible intended-parent profiles and decides whom she is interested in meeting.
If both sides are interested, a facilitated conversation allows everyone to determine whether the match feels right.
Your fertility clinic performs final medical screening of the surrogate.
You and the surrogate each have separate legal representation.
Financial and insurance arrangements are completed before embryo transfer.
Once medical and legal clearance are complete, the clinic prepares the surrogate for transfer.
You can read our detailed Surrogate Matching Guide and Gestational Surrogate Medical Screening Guide for more information.
That fear is understandable.
Especially after repeated unsuccessful transfers.
Using a gestational surrogate does not guarantee implantation.
No embryo transfer can guarantee pregnancy.
Your fertility specialist should help you understand:
The purpose of using a surrogate is not to create certainty.
It is to change one variable—the person carrying the pregnancy—when there is medical reason to believe that variable matters.
Previous failed transfers do not automatically make transferring multiple embryos safer or more appropriate.
Multiple pregnancy carries additional risks for the surrogate and babies.
Embryo-transfer decisions should be made with your fertility clinic and discussed with the surrogate before matching and legal clearance.
ASRM’s gestational-carrier guidance specifically identifies disagreement over the number of embryos transferred as a reason a proposed match may be inappropriate.
A surrogate should know and agree to the embryo-transfer plan before treatment begins.
This is another common emotional challenge.
During your own IVF treatment, you may have controlled almost everything you could:
Medications.
Appointments.
Food.
Exercise.
Testing.
Transfer day.
Then surrogacy requires trusting another woman with the pregnancy.
That adjustment can be difficult.
Good matching helps enormously.
So do clear expectations.
Before pregnancy, talk openly about:
At the same time, remember that the surrogate remains the patient and makes decisions about her own medical care.
The goal is not to find someone you can control.
It is to find someone you trust.
Consider asking:
What do you believe has caused our unsuccessful IVF or transfers?
Is the problem more likely embryo-related or uterine/gestational?
Do we have embryos you consider appropriate for transfer?
Have we adequately evaluated the uterine cavity?
Do you believe another transfer to me has a reasonable chance of success?
If we repeat the same approach, what would you expect to be different?
Would you recommend donor eggs before surrogacy? Why?
Would you recommend a gestational carrier in our case? Why?
What evidence makes you believe a gestational carrier could improve our chances?
Would you recommend creating additional embryos before we start matching?
The most useful answer should explain why a surrogate does—or does not—address your specific reproductive problem.
Medicine is only part of the decision.
Ask yourself:
Am I continuing IVF because my doctor believes it remains promising—or because I’m afraid to stop?
How is treatment affecting my physical health?
How is it affecting my relationship?
How much emotional energy do I have left?
What financial impact would another retrieval or transfer have?
Would I feel relieved if someone else could carry the pregnancy?
What part of not carrying is hardest for me to accept?
Am I ready to learn about surrogacy without committing to it yet?
Exploring surrogacy does not obligate you to pursue it.
Sometimes learning what the process actually involves makes the decision easier in either direction.
There is no universal number. What matters is why treatment is failing and whether changing the person carrying the pregnancy addresses the suspected problem.
ASRM says gestational carriers may be considered after multiple unexplained IVF failures involving good-quality embryos and, in its 2026 recurrent implantation failure guidance, after several failed embryo transfers.
Usually not by itself. Even high-quality embryos do not implant every time.
That is more significant and should prompt a detailed conversation with your reproductive endocrinologist. Current ASRM guidance considers recurrent implantation failure based on cumulative expected implantation rates and notes that several failed euploid transfers may meet the definition.
No. A gestational carrier changes the gestational environment, not embryo genetics.
A surrogate cannot make chromosomally abnormal embryos normal. Ask your fertility specialist whether egg quality, sperm factors, or another embryo-related issue needs to be addressed.
Possibly, if your primary challenge is egg quality, ovarian reserve, repeated aneuploid embryos, or another egg-related factor.
Sometimes, depending on the cause. Recurrent pregnancy loss should be evaluated before assuming another uterus is the solution.
That can be a direct medical indication for gestational surrogacy, even if you have not experienced repeated failed transfers.
Yes. Learning about the process does not commit you to pursuing it. However, the medical decision about whether a gestational carrier makes sense in your situation should be made with your fertility specialist.
Not necessarily. Many intended parents contact us while still creating embryos or deciding whether surrogacy is their next step.
No. Surrogacy cannot guarantee implantation, pregnancy, or live birth.
Review our Surrogacy Process for Intended Parents, learn how surrogate matching works, or contact Simple Surrogacy to understand the process while you continue discussing the medical side with your fertility specialist.
People undergoing infertility treatment can become trapped by one thought:
Maybe we should try just one more time.
Sometimes that is exactly the right decision.
And sometimes it isn’t.
There is no prize for undergoing the greatest number of IVF cycles before considering another path.
There is also no reason to move to surrogacy if the medical evidence suggests the uterus is not the problem.
The most useful question is:
What is actually preventing us from having a child—and which option addresses that problem most directly?
If embryo creation is the problem, focus there.
If egg quality is the problem, donor eggs may deserve consideration.
If pregnancy is unsafe, the uterus cannot carry, or repeated appropriate embryo transfers have failed and your fertility specialist believes the gestational environment may be contributing, surrogacy may be the next logical step.
Moving from IVF to surrogacy is not abandoning your plan to become a parent.
It is changing the plan for how you get there.
At Simple Surrogacy, we have worked with intended parents making that transition since 2002. Our role is not to tell you when to stop fertility treatment—that is a decision for you and your medical team.
Our role is to help you understand what comes next if gestational surrogacy becomes part of the answer.
When you are ready to explore it, review our Intended Parent Surrogacy Process or contact us with your questions.
You do not have to commit to a journey in order to begin understanding your options.
