Surrogacy

Surrogacy is an arrangement in which one person carries and gives birth to a baby for another individual or couple. In fertility care, surrogacy can be an important path to parenthood for people who cannot safely carry a pregnancy, for same-sex male couples, and for some individuals facing infertility, recurrent pregnancy loss, or serious medical conditions. Because surrogacy involves medical treatment, legal contracts, ethical considerations, and emotional planning, understanding how it works is essential before taking next steps.

What Is Surrogacy?

Surrogacy is a form of assisted reproduction in which a woman, often called a surrogate or gestational carrier, carries a pregnancy intended for another person or couple, known as the intended parent or intended parents. In modern fertility medicine, surrogacy usually means gestational surrogacy, where the carrier is not genetically related to the baby because the embryo is created through in vitro fertilization (IVF) and then transferred to the uterus.

Surrogacy matters because pregnancy and genetic parenthood are not always possible through intercourse or standard fertility treatment alone. For some people, surrogacy may be the safest or only realistic option for building a family.

Major medical organizations, including the American Society for Reproductive Medicine, recognize gestational surrogacy as an established reproductive option when appropriately screened, ethically managed, and legally structured.

At a glance

Surrogacy involves one person carrying a pregnancy for intended parent(s).
Most surrogacy today is gestational, not traditional.
It is commonly used in infertility care and family building.
It often involves IVF, embryo transfer, medical screening, and legal contracts.
For men, surrogacy is especially relevant in male factor infertility and same-sex male family building.

Key Takeaways

Surrogacy is not a diagnosis or disease; it is a reproductive pathway.
Gestational surrogacy is the most common and medically standard form today.
Surrogacy may be considered when pregnancy is medically unsafe, impossible, or unsuccessful through other treatments.
For male fertility patients, sperm testing, genetic screening, and IVF planning are often central parts of the process.
Legal rules vary widely by state and country, so specialized legal guidance is essential.
The surrogate requires thorough medical and psychological screening before treatment.
Surrogacy can be medically successful, but it is complex, expensive, and emotionally demanding.
A fertility clinic can help determine whether surrogacy, IVF, donor eggs, donor sperm, or other options make the most sense.

Types of Surrogacy

Gestational surrogacy

In gestational surrogacy, the embryo is created using IVF and transferred to the gestational carrier. The egg may come from the intended mother, an egg donor, or previously created embryos. The sperm may come from the intended father, a sperm donor, or frozen sperm.

This is the standard approach used by most fertility clinics because the carrier does not provide the egg and therefore is not genetically related to the child.

Traditional surrogacy

In traditional surrogacy, the surrogate also provides the egg, meaning she is genetically related to the child. This approach is much less common today because it raises significantly more legal, emotional, and ethical complexity.

Comparison table

Type	Who provides the egg?	Carrier genetically related to baby?	How pregnancy is usually created	How common is it today?
Gestational surrogacy	Intended mother or egg donor	No	IVF embryo transfer	Most common
Traditional surrogacy	Surrogate	Yes	Insemination or fertility treatment	Much less common

When people search for "surrogate mother," they are often referring to either model, but in clinical practice, gestational carrier is a more precise term for modern IVF-based surrogacy.

Why Surrogacy Is Used

Surrogacy may be considered for several reasons. Some are medical, some are anatomical, and some relate to family structure.

Common reasons people pursue surrogacy

Absence of a uterus, whether congenital or following surgery such as hysterectomy
Severe uterine disease or structural issues that prevent pregnancy
Medical conditions that make pregnancy dangerous, such as serious heart disease or some autoimmune disorders
Recurrent implantation failure or recurrent pregnancy loss in carefully selected cases
Same-sex male couples who need both an egg source and a gestational carrier
Single men pursuing parenthood
Some cancer survivors whose prior treatment affected reproductive options

The American College of Obstetricians and Gynecologists and the National Cancer Institute both note that fertility preservation and alternative family-building pathways may be important after cancer treatment.

What surrogacy does not mean

Surrogacy does not automatically mean a man has infertility. Some intended fathers have normal semen parameters and use surrogacy because a partner cannot carry a pregnancy or because they are pursuing parenthood without a female partner. In other cases, male factor infertility is part of the picture and IVF with intracytoplasmic sperm injection (ICSI) may be needed.

How the Surrogacy Process Works

The exact path varies, but most surrogacy journeys follow a structured sequence.

Typical surrogacy process

Initial fertility consultation: Intended parent(s) meet with a reproductive endocrinology clinic to review goals, fertility history, and treatment options.
Fertility testing: This may include semen analysis, hormone testing, infectious disease screening, ovarian reserve testing, and genetic carrier screening.
Choosing an egg source: Eggs may come from a partner, donor, or previously frozen embryos.
Matching with a gestational carrier: This may happen through an agency, independent arrangement, or fertility program.
Medical and psychological screening: The carrier is evaluated for general health, uterine health, obstetric history, infection risk, and readiness for the process.
Legal contracts: Separate legal counsel is typically recommended for intended parents and the carrier before medications or embryo transfer.
IVF cycle: Eggs are retrieved, fertilized, and embryos are cultured in the lab. Preimplantation genetic testing may be discussed in select cases.
Embryo transfer: A prepared embryo is transferred to the gestational carrier's uterus.
Pregnancy monitoring: Blood testing and ultrasound confirm implantation and ongoing pregnancy.
Prenatal care and delivery: The carrier receives obstetric care through pregnancy until birth.

The CDC Assisted Reproductive Technology program explains that IVF success depends on many factors, including age of the egg source, embryo quality, and clinic-specific practices.

What Surrogacy Means in Men's Health and Fertility

For men, surrogacy often sits at the intersection of sperm health, fertility treatment, genetics, and family planning. It may come up in several scenarios:

A male partner has healthy sperm, but the female partner cannot safely carry a pregnancy.
A man has low sperm count, poor sperm motility, or abnormal sperm morphology and needs IVF or ICSI as part of the surrogacy plan.
A same-sex male couple uses donor eggs plus a gestational carrier.
A single man uses donor eggs and a gestational carrier.
A man froze sperm before chemotherapy, radiation, vasectomy, or gender-affirming treatment and later uses that sperm in IVF with a surrogate.

Male fertility factors that can affect a surrogacy journey

Sperm count: Lower counts may reduce fertilization odds without advanced lab techniques.
Sperm motility: Poor movement can make natural conception difficult and may push care toward ICSI.
Sperm morphology: Abnormal shape can be associated with lower fertilization potential, though interpretation is nuanced.
Sperm DNA fragmentation: In some cases, this may be discussed when there is recurrent IVF failure or recurrent pregnancy loss, though testing and interpretation remain context-dependent.
Hormonal problems: Low testosterone, pituitary disorders, or other endocrine issues can contribute to infertility. Importantly, exogenous testosterone can suppress sperm production, as described by the NIH Endotext.
Genetic issues: Y chromosome microdeletions, karyotype abnormalities, or CFTR-related conditions may influence treatment decisions and counseling.

For intended fathers, surrogacy does not erase the importance of a full male fertility evaluation. In many cases, improving the sperm side of the equation can meaningfully affect embryo quality, IVF efficiency, and the number of available embryos for transfer.

Medical Screening and Fertility Testing

Surrogacy is not diagnosed by a single test. Instead, it is usually the result of fertility evaluation, medical history, and treatment planning.

Testing commonly involved for intended parents

Semen analysis
Male hormone testing when indicated, such as FSH, LH, total testosterone, estradiol, prolactin, and thyroid testing
Infectious disease screening required for ART treatment
Genetic carrier screening
Karyotype or specialized male infertility testing in select cases
Assessment of frozen sperm or testicular sperm if needed

Testing commonly involved for a gestational carrier

Detailed medical history and prior pregnancy history
Uterine evaluation
Infectious disease screening
General health screening
Psychological evaluation
Medication review and lifestyle screening

Key fertility tests table

Test or evaluation	What it looks at	Why it matters in surrogacy
Semen analysis	Sperm count, motility, morphology, volume	Helps determine whether IVF or ICSI may be needed
Male hormone panel	Hormonal causes of infertility	May identify treatable contributors to poor sperm production
Genetic carrier screening	Inherited recessive conditions	Helps assess reproductive risk before embryo creation
Infectious disease screening	Transmissible infections	Required for safety and ART compliance
Carrier uterine evaluation	Uterine structure and readiness	Assesses suitability for embryo transfer and pregnancy
Embryo assessment	Development and quality in the lab	Guides transfer planning and expected success

The World Health Organization provides standardized guidance for semen examination in the WHO Laboratory Manual for the Examination and Processing of Human Semen.

What's Normal vs What's Not?

Because surrogacy is a treatment pathway rather than a medical condition, there is no "normal range" for surrogacy itself. What clinicians look for instead is whether the medical, fertility, and legal pieces are suitable for a safe and realistic process.

Generally favorable findings

A clear medical reason for using surrogacy
A viable sperm source and, when needed, egg source
Embryos available or a reasonable plan to create them
A gestational carrier who meets medical and psychological screening standards
Legal clearance in the relevant jurisdiction

Findings that may complicate the process

Severely impaired sperm production or inability to retrieve viable sperm
Poor embryo development across multiple IVF cycles
Untreated infectious disease concerns
Genetic findings that require counseling
A carrier who does not meet medical screening criteria
Residence in a jurisdiction with restrictive or unclear surrogacy laws

In men's fertility care, a "not normal" finding often refers to semen analysis abnormalities, hormonal disruption, or a history suggesting genetic or obstructive infertility. These issues do not always prevent surrogacy, but they can influence timelines, cost, and treatment design.

Risks and Important Considerations

Surrogacy can be highly effective, but it is never simple. The main considerations span medical, psychological, practical, and legal domains.

Medical considerations

IVF carries burdens and risks for the egg provider, including ovarian hyperstimulation in some cases.
Pregnancy always carries risk for the gestational carrier, including gestational diabetes, hypertensive disorders, cesarean delivery, and postpartum complications. The CDC outlines common pregnancy complications.
Multiple pregnancy risk increases if more than one embryo is transferred, which is why single embryo transfer is often encouraged when appropriate.
Not every embryo transfer works, and some journeys involve failed cycles or miscarriage.

Emotional considerations

Long timelines and uncertainty can be stressful.
Relationship expectations should be discussed early.
Failed cycles or pregnancy loss can be emotionally significant for all parties.
Clear communication and psychological support are often helpful.

Legal considerations

Surrogacy law differs substantially by state and country.
Parentage orders and contract enforceability vary.
Compensation rules may differ across jurisdictions.
Independent legal counsel is important for everyone involved.

Surrogacy vs Other Family-Building Options

Surrogacy is just one of several paths to parenthood. The right option depends on medical facts, values, budget, timing, and legal context.

Option	Best suited for	Main advantages	Main limitations
Surrogacy	People who cannot safely carry a pregnancy or need a gestational carrier	Can allow genetic parenthood using IVF	Complex, expensive, legally sensitive
IVF without surrogacy	People able to carry a pregnancy	Widely used fertility treatment	Not an option if pregnancy is unsafe or impossible
Donor eggs	Low ovarian reserve, poor egg quality, same-sex male couples	Can improve embryo creation chances	No genetic link to intended mother
Donor sperm	Severe male factor infertility or solo/same-sex female parenting	Can bypass absent or poor sperm source	No genetic link to intended father
Adoption	Individuals or couples open to non-biologic parenthood	Does not require fertility treatment	Separate legal and logistical complexity

A fertility specialist can help compare likely success, cost, time, and medical fit across these options.

Cost, Legal, and Ethical Issues

Cost

Surrogacy is often one of the most expensive fertility pathways because it may include agency fees, legal fees, IVF treatment, medications, insurance review, screening, compensation, travel, and obstetric care. Total cost varies widely based on location and circumstances.

Legal issues

Some places are friendly to surrogacy, some are restrictive, and some prohibit certain forms entirely. International surrogacy can add immigration and citizenship questions. Because laws evolve, intended parents should work with attorneys who specifically handle reproductive law.

Ethical issues

Ethical discussions around surrogacy often focus on informed consent, fair compensation, autonomy, exploitation concerns, and the best interests of the child. The ASRM Ethics Committee has published guidance on ethical practices in assisted reproduction, including gestational carrier arrangements.

Common Myths About Surrogacy

Myth: The surrogate is always the baby's biological mother.

Not in gestational surrogacy. In that much more common model, the carrier does not provide the egg.

Myth: Surrogacy is only for women with infertility.

No. Surrogacy is also used by same-sex male couples, single men, cancer survivors, and people with serious health conditions unrelated to infertility itself.

Myth: If a man has poor sperm, surrogacy fixes the problem.

Surrogacy solves the pregnancy-carrying part of reproduction, not necessarily the sperm problem. Male fertility issues still often need evaluation and treatment.

Myth: Surrogacy guarantees a baby.

No fertility treatment can guarantee success. Outcomes depend on sperm quality, egg quality, embryo development, uterine receptivity, age, medical history, and chance.

Myth: All surrogacy is legal everywhere.

It is not. Laws differ widely and should be reviewed early.

Frequently Asked Questions

Is surrogacy the same as IVF?

No. IVF is the laboratory process used to create embryos. Surrogacy is the broader family-building arrangement in which another person carries the pregnancy. Many surrogacy journeys use IVF, but the terms are not interchangeable.

Can a man with low sperm count still use surrogacy?

Often, yes. A low sperm count does not automatically rule out surrogacy. Many intended fathers with male factor infertility conceive through IVF with ICSI, sperm retrieval procedures, donor sperm, or previously frozen sperm, depending on the case.

Does surrogacy require donor eggs?

Not always. If a female partner or intended mother has usable eggs, those may be used. Donor eggs are common in some surrogacy arrangements, especially for same-sex male couples or when egg quality is a limiting factor.

Is the surrogate genetically related to the baby?

In gestational surrogacy, no. In traditional surrogacy, yes. Gestational surrogacy is much more common today.

How long does the surrogacy process take?

It varies widely. Screening, matching, legal review, IVF, transfer, and pregnancy mean the process often takes many months and sometimes longer than a year.

Is surrogacy safe?

Surrogacy can be medically managed safely, but pregnancy and IVF are never risk-free. Careful screening, experienced clinics, and clear legal and medical planning help reduce risk.

Can single men pursue surrogacy?

Yes. Single men may pursue surrogacy, often using donor eggs and IVF, subject to clinic policies and local legal requirements.

Is surrogacy legal in every state or country?

No. The legality and structure of surrogacy vary substantially. Anyone considering surrogacy should get advice from a reproductive law attorney in the relevant location.

Do you need a medical reason to use surrogacy?

Not always. Some people use surrogacy because of family structure rather than a medical condition, such as same-sex male couples or single men.

When should we talk to a fertility doctor about surrogacy?

As early as possible if pregnancy is medically unsafe, anatomically impossible, repeatedly unsuccessful, or if your family-building plan will clearly require a gestational carrier.

Gestational carrier: A person who carries a pregnancy created from an embryo that is not genetically hers.
Traditional surrogate: A surrogate who provides the egg and is genetically related to the child.
IVF: In vitro fertilization, the process of creating embryos in a lab.
ICSI: Intracytoplasmic sperm injection, where a single sperm is injected into an egg.
Semen analysis: The standard lab test used to assess sperm quantity and quality.
Embryo transfer: Placement of an embryo into the uterus.
Egg donor: A person who provides eggs used to create embryos.
Genetic carrier screening: Testing for inherited conditions that could affect offspring.
