Surrogate Pregnancy: What It Is, How It Works, and What Everyone Involved Can Expect

Updated June 2026

QUICK ANSWER: A surrogate pregnancy is a pregnancy carried by a woman on behalf of intended parents, using an embryo created through IVF. The surrogate has no genetic connection to the child. The process involves medical screening, legal contracts, an embryo transfer procedure, and a full pregnancy. From agency enrollment through birth, the complete surrogacy journey typically takes 15 to 18 months.

Surrogacy is one of the most collaborative and legally structured paths in reproductive medicine, and for the intended parents and surrogates who go through it, one of the most personal. This guide covers what a surrogate pregnancy actually involves: how it works medically, what the legal framework looks like, what surrogates and intended parents each experience, and what realistic timelines and expectations look like for both.

What Is a Surrogate Pregnancy?

A surrogate pregnancy is a pregnancy carried by a woman who is not the intended parent of the child. Gestational surrogacy is the most common form today, in which the surrogate carries an embryo that was created through in vitro fertilization (IVF) and has no genetic connection to the baby she is carrying. The embryo is formed using the intended parents’ eggs and sperm, donor eggs, donor sperm, or some combination, depending on the intended parents’ situation.

This is distinct from traditional surrogacy, in which the surrogate provided her own egg and was therefore genetically related to the child. Traditional surrogacy is rarely practiced today and is not supported by most agencies, including Elevate Baby, due to the significantly more complex legal and psychological dynamics it creates.

Who Pursues Surrogacy?

Intended parents turn to surrogacy for a range of medical and personal reasons, including uterine conditions such as Müllerian agenesis or a history of hysterectomy, recurrent pregnancy loss, medical conditions that make pregnancy unsafe (cancer treatment, heart conditions, autoimmune disorders), age-related factors affecting the ability to carry a pregnancy, and a history of multiple failed IVF attempts.

Surrogacy is also the primary path to biological parenthood for same-sex male couples, who require both an egg donor and a gestational surrogate. Single intended parents, both men and women, pursue surrogacy as well. Elevate Baby supports intended parents of all backgrounds, orientations, and family structures, and has experience working with LGBTQ+ families, single parents, and international intended parents.

How Does a Surrogate Pregnancy Work? The Medical Process

Step 1: Embryo Creation

Before a surrogate can become pregnant, embryos must be created. The intended parents work with a fertility clinic to produce embryos through IVF. If the intended mother has viable eggs, they are retrieved and fertilized with her partner’s sperm (or donor sperm). If an egg donor is needed, she is identified, and her eggs are used. The resulting embryos are cultured in the lab for five to six days, and viable embryos may undergo preimplantation genetic testing (PGT) before any transfer is planned.

Step 2: Surrogate Screening and Matching

Surrogate candidates undergo a comprehensive screening process before any match is made. At Elevate Baby, this includes a full medical evaluation, review of prior pregnancy and delivery history, infectious disease testing, genetic carrier screening, a psychological evaluation by a licensed mental health professional, a background check on all household members, and a home assessment. Matching is based on compatibility between the surrogate’s profile and the intended parents’ preferences and timeline.

Step 3: Legal Contracts

Before any medical process begins, a gestational surrogacy agreement is executed between the surrogate and the intended parents. This legally binding contract, drafted and reviewed by attorneys representing both parties independently, establishes the rights and responsibilities of all parties involved, including parental rights, compensation structure, medical decision-making, and scenarios that may arise. Legal agreements are non-negotiable prerequisites, not formalities.

In surrogacy-friendly states, a pre-birth order is typically obtained during the pregnancy, establishing the intended parents as the legal parents of the child before birth. This means the intended parents are listed on the birth certificate from the start, and no adoption proceedings are required.

Step 4: Embryo Transfer

Once contracts are signed and the surrogate has completed a medical preparation protocol, the embryo transfer procedure takes place at the fertility clinic. The transfer is a brief outpatient procedure with no sedation required, in which one or two embryos are placed directly into the surrogate’s uterus using a thin catheter guided by ultrasound. The surrogate rests briefly afterward and returns home the same day. A pregnancy test is performed approximately ten days later.

Step 5: Pregnancy and Prenatal Care

If the transfer results in a confirmed pregnancy, the surrogate transitions to her own OB/GYN for ongoing prenatal care. The intended parents are typically involved throughout the pregnancy, attending appointments, staying in regular contact with the surrogate, and preparing for the birth. The level of contact and involvement is agreed upon during the matching process and reflected in the legal contract.

Step 6: Delivery and Transition

In most cases, the intended parents are present at the time of delivery. Legal parentage is already established via the pre-birth order, so the intended parents assume full parental care of the child immediately. The surrogate’s formal role in the journey concludes at birth, though many surrogates and intended parent families maintain relationships afterward.

Surrogate Requirements at Elevate Baby

Not everyone is a candidate for surrogacy, and Elevate Baby follows strict medical and psychological guidelines to ensure the safety and readiness of every surrogate before she is matched with intended parents. Elevate Baby’s surrogate requirements include:

Being between the ages of 21 and 40, having a healthy BMI of 32 or below, being a non-smoker with no history of illicit drug use, having given birth at least once (and no more than five times), having a history of healthy pregnancies and deliveries, having had no more than three prior cesarean sections, being financially independent, having reliable transportation, permanently residing in the United States in a surrogacy-friendly state, and having a support system of family and friends.

Candidates who do not meet these requirements are not approved. This is not a gatekeeping measure but a medical and ethical standard that protects the surrogate’s health and the integrity of the process.

How Long Does the Surrogacy Process Take?

The full surrogacy journey (from agency enrollment through the birth of the child) typically takes 15 to 18 months, though individual timelines vary based on how quickly a match is made, how many embryo transfer attempts are needed, and other factors.

A general timeline looks like this: 

• agency enrollment and surrogate screening: one to three months
• matching with intended parents: one to three months
• legal contracts: approximately two to four weeks
• medical preparation and embryo transfer: four to six weeks
• pregnancy and prenatal care: approximately nine months
• and delivery concludes the process

The matching phase is typically the most variable. Intended parents with specific preferences for their surrogate, or surrogates waiting for the right match, may experience a longer timeline here.

Compensation and Costs

For surrogates: Gestational surrogates receive compensation for the significant physical and time commitment of carrying a pregnancy for another family. Compensation varies based on experience, location, and the specific terms of the arrangement, and is fully detailed in the gestational surrogacy agreement.

In addition to base compensation, surrogates are reimbursed for pregnancy-related expenses, including medical co-pays, maternity clothing, travel to monitoring appointments, and other costs directly tied to the surrogacy. 

For intended parents: Total costs for surrogacy in the United States typically range from $100,000 to $180,000 or more, encompassing agency fees, surrogate compensation, IVF cycle costs, legal fees, and related expenses. When egg donation is also required, costs are higher. We walk you through a full cost breakdown during the initial consultation.

What the Surrogacy Experience is Like, for Both Sides

For Surrogates

Most surrogates describe the experience as meaningful but also a major commitment. The stimulation medications and the physical realities of pregnancy require real commitment. The emotional side of carrying a child for another family affects surrogates differently. Agencies carefully screen and support throughout the process, but what helps most is having clear expectations, a solid support system, and a team that stays accessible and communicative throughout.

For Intended Parents

For most intended parents, surrogacy follows a period of significant trying. The surrogacy journey can be emotionally complex in its own right: there is hope, anxiety, gratitude, and sometimes a sense of helplessness from not being the one carrying the pregnancy. Staying actively involved by communicating regularly with the surrogate, attending appointments, and building the relationship helps most intended parents feel connected and grounded during the process.

After the Baby Is Born

Some surrogate-intended parent relationships continue after delivery; others conclude warmly but formally. This is a personal decision, and the right choice is whatever both parties genuinely want. What matters is that expectations about post-birth contact are discussed honestly during the matching process and reflected in the legal agreement so that no one is surprised.

How a Surrogacy Agency Supports the Process

A surrogacy agency coordinates the people, timelines, and logistics required for surrogacy. This includes surrogate recruitment and screening, matching, legal coordination, appointment scheduling, financial management (escrow for surrogate compensation), ongoing case management, and emotional support for both parties throughout the journey.

Working without an agency is possible in some states, but it significantly increases the complexity and risk for both surrogates and intended parents. An experienced agency also reduces the likelihood of mismatches, legal complications, and logistical breakdowns that can derail an otherwise sound arrangement.
