Surrogate: What Patients Need to Know

A surrogate is a woman who carries a pregnancy for intended parent or parents, most often through a carefully planned medical process using IVF. Understanding the medical steps, screening, risks, and legal considerations can help patients make informed decisions about whether surrogacy is the right path to family building.

Overview: what a surrogate is

A surrogate is a woman who carries and gives birth to a baby for another person or couple, often called the intended parent or intended parents. In current medical practice, this usually means a gestational surrogate, where an embryo is created through in vitro fertilization and transferred to the surrogate’s uterus. In this arrangement, the surrogate is typically not genetically related to the baby.

Surrogacy may be considered when pregnancy is medically unsafe, not possible, or unlikely to succeed. It can be an option for some women with uterine conditions, people who have had repeated IVF failure, intended parents in same-sex male couples, and some single individuals who wish to build a family. The decision is deeply personal and often involves medical, emotional, ethical, and legal questions.

There are two broad terms people may hear. Gestational surrogacy uses an embryo created from the egg and sperm of the intended parents or donors. Traditional surrogacy involves the surrogate’s own egg and is much less commonly used in many medical systems because it raises additional legal and emotional complexities.

For patients, the most important point is that surrogacy is not a single procedure but a coordinated process. It usually includes fertility testing, counseling, legal review, IVF planning, embryo transfer, prenatal care, and delivery planning.

Who may consider surrogacy

Surrogacy may be discussed when carrying a pregnancy is not medically possible or would involve serious risk. Examples include absence of the uterus, significant uterine scarring, certain congenital uterine differences, repeated implantation failure, or health conditions in which pregnancy could worsen heart, kidney, autoimmune, or other systemic disease. Some people also consider surrogacy after repeated pregnancy loss when other causes have been evaluated and treated.

Surrogacy can also be relevant for intended parents who need both assisted reproduction and a person to carry the pregnancy. This may include men in same-sex relationships, some transgender women, and single men. In other situations, embryos may be created using donor eggs, donor sperm, or both, depending on the fertility profile and treatment plan.

Before surrogacy is recommended, clinicians usually review whether other family-building options are suitable. Depending on the person’s history, this may include treatment for underlying infertility, uterine surgery, or standard assisted reproduction. Helpful background information may also be found in infertility resources and in overviews of IVF treatment.

Not every patient is a candidate, and not every country permits the same forms of surrogacy. A fertility specialist can explain which pathways may be medically appropriate and legally available based on the patient’s diagnosis, goals, and location.

How the surrogacy process works

The process usually begins with medical consultation and planning. Intended parents often undergo fertility evaluation, including hormone testing, imaging, semen analysis when relevant, and review of prior pregnancies or IVF cycles. If embryos are not already available, egg retrieval and fertilization are planned using the intended parents’ or donors’ gametes.

The surrogate also goes through extensive screening. This commonly includes review of general health, prior pregnancy history, uterine assessment, infectious disease testing, and psychological evaluation. The goal is to support a safe pregnancy and to identify issues that could affect the surrogate or the baby.

Once screening and legal agreements are completed, the surrogate’s uterine lining is prepared with medications so it is ready for embryo transfer. One or more embryos may be transferred, depending on the medical plan and local practice standards, although single embryo transfer is often preferred to reduce the risks linked with twins or higher-order multiples. The pregnancy test is then checked about two weeks later.

If pregnancy occurs, the surrogate receives routine prenatal care, along with communication between the obstetric team, fertility specialists, and intended parents. Some patients may benefit from specialized embryo transfer procedures or egg freezing earlier in the family-building journey if fertility preservation is needed before treatment can begin.

Medical risks and health considerations

A surrogate pregnancy carries many of the same risks as any pregnancy. These include miscarriage, ectopic pregnancy, bleeding, infection, high blood pressure disorders such as preeclampsia, gestational diabetes, preterm birth, cesarean delivery, and postpartum complications. The embryo transfer process itself is usually brief and minimally invasive, but the medications used for cycle preparation may cause temporary side effects.

For intended parents, risks may relate to IVF steps such as ovarian stimulation and egg retrieval, if they are using their own eggs. Emotional strain is also common. Uncertainty around treatment timing, pregnancy outcomes, and legal processes can be stressful for everyone involved, including the surrogate and her family.

Multiple pregnancy is an especially important consideration. Twins can increase the chance of preterm birth, maternal complications, and newborn intensive care needs. For this reason, fertility teams often discuss strategies that support the safest possible outcome, including careful embryo selection and limiting the number transferred.

Patients should also understand that surrogacy does not remove all uncertainty. Even with normal screening and a good-quality embryo, implantation may not occur, or pregnancy may not continue. Clear counseling helps families prepare realistically while still moving forward with hope and support.

Evaluation, legal planning, and emotional support

Good surrogacy care goes beyond fertility treatment alone. Medical teams typically work together with mental health professionals, obstetric clinicians, and legal advisers. Counseling can help intended parents and surrogates discuss expectations about communication, decision-making during pregnancy, confidentiality, and plans around birth and postpartum contact.

Legal review is essential because surrogacy laws vary widely. Some countries permit only certain forms of surrogacy, some restrict compensation, and some do not recognize surrogacy arrangements at all. Legal agreements are usually completed before medications or embryo transfer begin, so each party understands responsibilities and parental rights according to local law.

Doctors also assess whether there are underlying health issues that should be treated before proceeding. This might include workup for recurrent pregnancy loss, evaluation of the uterus, or testing related to male factor fertility. In some cases, patients may need broader fertility support such as ICSI when sperm-related fertilization challenges are present.

Strong communication and coordinated planning often make the process smoother. Patients may wish to ask who will provide prenatal care, how updates will be shared, what decisions will be made if complications arise, and how delivery and newborn care will be organized in advance.

Alternatives and self-care during decision-making

Surrogacy is one of several family-building options. Depending on diagnosis and personal values, alternatives may include trying pregnancy with medical treatment, using donor eggs or donor sperm, adoption, or choosing not to pursue parenthood. A careful review of the medical reason for considering surrogacy can help patients compare these options more clearly.

Self-care matters because this process can be emotionally demanding. Many intended parents benefit from counseling, peer support groups, or regular check-ins with a trusted clinician. Keeping written notes, timelines, and question lists can make appointments more productive and help everyone stay aligned.

For surrogates, healthy pregnancy habits remain important: attending prenatal visits, taking recommended supplements, avoiding tobacco and non-prescribed substances, staying physically active as advised, and speaking up promptly about new symptoms. Intended parents can support the process by respecting the surrogate’s health needs and maintaining clear, compassionate communication.

Near the end of planning or treatment, some international patients seek care from experienced multidisciplinary centers. Acibadem International’s fertility and women’s health specialists, together with its JCI-accredited hospitals, provide diagnosis and treatment pathways for patients exploring surrogacy-related fertility care where legally appropriate.

When to seek medical care

Anyone considering surrogacy should speak with a qualified fertility specialist early, especially if there is a history of infertility, repeated miscarriage, uterine surgery, severe medical illness, or prior IVF difficulties. Early evaluation can clarify whether surrogacy is medically indicated and what testing may be needed first.

A surrogate who is already pregnant should seek prompt medical attention for warning signs such as heavy bleeding, severe abdominal pain, fainting, chest pain, shortness of breath, severe headache, vision changes, reduced fetal movement later in pregnancy, or signs of labor too early. These symptoms do not always mean a serious problem, but they should not be ignored.

Intended parents should also seek professional support if the emotional strain becomes overwhelming. Anxiety, sleep problems, conflict around decision-making, or grief after failed cycles are common and deserve attention. Mental health care can be an important part of safe, compassionate fertility treatment.

Because legal frameworks differ so much, patients should also seek qualified legal advice before making commitments or traveling for care. Medical guidance and legal guidance work best together when planning any surrogacy journey.

Frequently asked questions

What is the difference between a surrogate and a gestational surrogate?

A surrogate is a general term for someone who carries a pregnancy for intended parents. A gestational surrogate specifically carries an embryo created through IVF and is usually not genetically related to the baby.

Is a surrogate the baby’s biological mother?

In gestational surrogacy, the surrogate is typically not the baby’s biological mother because her egg is not used. In traditional surrogacy, the surrogate’s egg is used, but this approach is less common in many modern fertility programs.

Why do people use a surrogate?

People may use a surrogate when pregnancy is not possible, has repeatedly not succeeded, or would pose significant health risks. Surrogacy may also help intended parents who need another person to carry the pregnancy, such as some same-sex male couples or single men.

Does surrogacy always require IVF?

Gestational surrogacy usually requires IVF because an embryo must be created and transferred to the surrogate’s uterus. Traditional surrogacy may not require IVF, but it is less commonly used due to added medical, legal, and emotional complexity.

What tests are done before surrogacy?

Testing often includes fertility evaluation for intended parents and health screening for the surrogate. This may involve blood tests, infectious disease screening, uterine assessment, review of past pregnancies, and psychological evaluation.

Is surrogacy medically safe?

Surrogacy can be carried out safely with careful screening and appropriate prenatal care, but no pregnancy is risk-free. The surrogate still faces the usual risks of pregnancy, so close follow-up with qualified clinicians is essential.

Are surrogacy laws the same everywhere?

No. Surrogacy laws vary widely between countries and sometimes within regions of the same country. Patients should always obtain legal advice in addition to medical advice before starting the process.
