Summary

Who this is for: Single men who want a biological child and are seriously researching whether surrogacy is a real option for them, not just in theory but in practice.

Key takeaways:

• Yes, single men can have a biological child through gestational surrogacy. It is legal, established, and more accessible than most people initially think.
• The process requires your sperm, an egg donor, and a gestational surrogate. You are the sole biological and legal parent.
• Costs vary significantly by destination. U.S.-based programs run $140,000 to $200,000+. International programs in Colombia and Mexico start around $60,000 to $75,000.
• The process takes roughly 14 to 22 months from your first consultation to the birth.
• Tammuz has been supporting single men through this process since 2008. Many of our intended parents are single men, both gay and straight.

What’s inside:

• How gestational surrogacy works for a single man, step by step
• Why you need both an egg donor and a surrogate
• Legal parentage, and how it works when you’re the only intended parent
• Cost ranges across destinations
• The emotional and practical realities of going through this solo
• Common questions single men ask before starting

The question comes up constantly in consultations. “I’m single. Is this actually something I can do?”

The short answer is yes. The longer answer is that there are real things to plan for, and the process works a little differently when you’re doing it on your own rather than as part of a couple. But single men have biological children through surrogacy every year. Tammuz has helped many of them. It’s not rare, and it’s not an edge case.

This guide is for single men who want to understand what’s actually involved before making any decisions. No pitch. Just a clear explanation of how it works.

The Basics: What Gestational Surrogacy Looks Like for a Single Man

Gestational surrogacy involves three parties: you, an egg donor, and a gestational surrogate.

Here’s how it works:

1. Your sperm is used to fertilize eggs from a donor through IVF. This creates embryos.
2. One of those embryos is transferred to the surrogate’s uterus.
3. The surrogate carries the pregnancy and gives birth.
4. Legal parentage is established based on your destination’s legal framework. You are the sole legal parent.

The surrogate has no genetic connection to the baby. Neither does the egg donor, once the embryo is transferred. The baby is biologically yours.

This is the standard model for single men, and it’s the same process used by gay couples, with the difference that there is one intended parent instead of two.

Why You Need Both an Egg Donor and a Surrogate

This is where some confusion comes up early in the research process.

You need a surrogate because you need someone to carry the pregnancy. You need an egg donor because you don’t have eggs. These are two separate people providing two separate things.

Some men assume a surrogate can also provide the eggs. She can, in what’s called traditional surrogacy. But traditional surrogacy is almost never recommended anymore because it creates significant legal complexity, the surrogate is genetically related to the child, and parental rights are much harder to establish clearly. Traditional surrogacy is rarely practiced, and most reputable agencies don’t offer it.

Gestational surrogacy, using a separate egg donor, is the standard. It’s cleaner medically and legally.

Selecting your egg donor is one of the earlier steps in the process. At Tammuz, you review detailed donor profiles that include health history, genetic background, education, physical characteristics, and photos. Some men choose an anonymous donor from a database. Others use a known donor, a friend or relative, who goes through the same screening process. Both approaches work.

What the Process Actually Looks Like

The surrogacy journey for a single man has a predictable structure. Here’s the sequence:

Step 1: Free Consultation You speak with Tammuz’s team about your goals, timeline, and destination options. This conversation is free and typically runs 30 to 60 minutes. It’s specific to your situation, not a general pitch.

Step 2: Program Selection You choose your destination: USA, Colombia, Mexico, or Armenia. Each has different costs, timelines, and legal frameworks. Tammuz walks you through what each one means for your specific case.

Step 3: Sperm Banking and Medical Evaluation You complete a semen analysis and bank sperm. This is typically coordinated through a clinic partner near your location or in your destination country.

Step 4: Egg Donor Selection You review donor profiles and select an egg donor. Your clinic coordinates the egg retrieval cycle.

Step 5: Embryo Creation Your sperm fertilizes the donor eggs through IVF. Embryos are created and can be genetically tested (PGT) before transfer to select the healthiest options.

Step 6: Surrogate Matching Tammuz matches you with a pre-screened surrogate. You can review her profile before the match is finalized. Surrogates go through medical, psychological, and background screening before being accepted into the program.

Step 7: Legal Contracts Before any medical procedures involving the surrogate begin, legal contracts are drafted and signed. For a single intended parent, the contract establishes that you are the sole legal parent.

Step 8: Embryo Transfer The surrogate receives the embryo. A pregnancy test follows approximately 10 to 14 days after transfer.

Step 9: Pregnancy Tammuz coordinates all prenatal care. You receive regular updates throughout the pregnancy and are involved in key milestones. Many single fathers are present at key appointments.

Step 10: Birth and Legal Exit Your baby is born. Legal parentage is confirmed, your name goes on the birth certificate, and travel documents are arranged if the birth is in another country. Tammuz coordinates the in-country process from birth to departure.

The full timeline runs approximately 14 to 22 months from your first consultation to bringing your baby home.

Legal Parentage When You’re the Only Intended Parent

One question single men ask a lot: how does legal parentage work when there’s only one of me?

The answer depends on destination, but the short version is that being a single intended parent is legally straightforward in Tammuz’s program destinations. The surrogacy contract establishes you as the sole intended parent. Pre-birth orders (in the U.S.) or post-birth court processes (in Colombia and Mexico) list you as the sole legal parent on the birth certificate.

You do not need to be partnered or married. Single status is not a legal obstacle in any of Tammuz’s program countries for single men.

One thing that matters: if you are a non-U.S. citizen pursuing surrogacy outside your home country, your child’s citizenship and passport process depends on your home country’s specific rules. Tammuz’s international client team navigates this for families from dozens of countries and can tell you exactly what to expect based on your nationality.

What Does It Cost?

Cost is the question most single men lead with, and it’s a fair one. Here’s the honest breakdown:

United States (program cost) $140,000 to $200,000+ depending on state, clinic, and program structure. California runs at the higher end. Legal protections are among the strongest in the world.

Colombia $60,000 to $75,000 for a guaranteed program. Strong LGBTQ+ and single-parent legal protections. Tammuz’s most common international destination for single men.

Mexico $65,000 to $80,000 for a structured program. Available for single men in Mexico City and specific state jurisdictions.

Armenia More affordable for some intended parents. Best discussed directly with Tammuz’s team for your specific situation.

These figures generally include agency fees, IVF, egg donor compensation, surrogate compensation, legal fees in the destination country, and medical costs. Travel, extended stays post-birth, and home-country legal steps are additional. Tammuz gives you a detailed cost breakdown before you commit to anything.

The significant cost gap between the U.S. and international options is real. For some single men, the U.S. is the right answer because of legal certainty or because they want the baby born on U.S. soil. For others, a Colombia or Mexico program at roughly one-third the cost makes the dream financially possible when it otherwise wouldn’t be.

What It’s Like to Go Through This as a Single Person

There’s a practical reality worth acknowledging. As a single intended parent, you are the sole point of contact for every decision. Medical updates come to you. Legal documents get signed by you. The agency communicates with you alone.

Most of the time this is fine. Single men navigate surrogacy journeys successfully every year, and being the sole decision-maker has its advantages: no disagreements, no need to sync schedules with a partner, no divided priorities.

Where it can get harder is emotionally. This is a significant journey, and doing it without a partner means your support has to come from elsewhere. Friends, family, a therapist, or the Tammuz community of other intended parents who have gone through similar journeys. None of those are substitutes for a partner, but they matter.

Tammuz’s case managers are in close contact with single intended parents throughout the process. This is not just administrative. Single fathers often have more questions, not fewer, and the relationship with your case manager is a real part of the support structure.

The Most Common Things Single Men Ask Before Starting

“Am I eligible as a single man?” Yes, in all of Tammuz’s program destinations. Single status is not a barrier.

“Will anyone judge me for doing this alone?” Not in this process. Tammuz has supported single men for over 15 years. Your family structure is not a novelty here.

“What if I meet someone during the journey?” Your program is based on your situation at the time you start. If your circumstances change, Tammuz’s team can advise on any legal or logistical considerations.

“What happens if the first transfer doesn’t work?” With a guaranteed program in Colombia or Mexico, additional program fees are not charged if the first transfer or first pregnancy does not result in a live birth. You continue to work through Tammuz’s program without paying a second full program fee.

“Is it weird to do this without a partner?” It’s not weird. It’s a choice an increasing number of men are making, and most of them are glad they did. The question is really: does the desire to be a father matter enough to you to do it this way? For the men who come to Tammuz, the answer is yes.

Frequently Asked Questions About Single Man Surrogacy

Can a single man legally become a parent through surrogacy?

Yes. In the U.S., Colombia, Mexico, and other Tammuz program destinations, single men are eligible to pursue gestational surrogacy. Legal contracts establish sole parentage before birth, and the intended father is listed on the birth certificate.

Does a single man need a partner to start a surrogacy program?

No. Single men participate in Tammuz’s programs without a partner. This is explicitly accommodated in program structure, legal contracts, and case management.

Why do you need both an egg donor and a surrogate?

A surrogate carries the pregnancy. An egg donor provides the eggs for fertilization. They are two separate roles. You cannot use the surrogate as the egg donor in gestational surrogacy, because that would create a genetic and legal connection between the surrogate and the baby, which complicates parentage significantly. Gestational surrogacy keeps these roles separate.

How do I select an egg donor?

Tammuz’s programs include access to a screened egg donor database. Profiles include health history, genetic background, education, photos, and personality information. You review profiles and make the selection. Known donors (a friend or family member) are also possible and go through the same screening process.

How long does the surrogacy process take for a single man?

The full timeline from initial consultation to birth runs approximately 14 to 22 months, depending on how quickly each phase moves. Surrogate matching and embryo creation are usually the longest steps.

What does surrogacy cost for a single man?

U.S.-based programs typically run $140,000 to $200,000+. International programs through Tammuz in Colombia and Mexico start around $60,000 to $75,000 for a guaranteed structure. Costs cover agency fees, IVF, egg donor compensation, surrogate compensation, and legal fees in the destination country.

What is a guaranteed program?

A guaranteed program means that if the first transfer or first pregnancy does not result in a live birth, additional program fees are not charged. You continue working within the program at no additional program cost. Tammuz offers guaranteed programs in Colombia and Mexico.

Does my nationality affect where I can pursue surrogacy?

Your nationality affects your baby’s citizenship and passport process but not your eligibility for Tammuz’s programs. Tammuz has supported intended fathers from dozens of countries. The international client team advises on citizenship and documentation specific to your home country.

What if I want my baby born in the United States?

U.S.-based surrogacy is available through Tammuz and provides the strongest legal protections. Costs are higher, but the baby is born on U.S. soil with U.S. citizenship established at birth. This is the right choice for some intended parents based on their specific priorities and nationality.

Can I use a known egg donor?

Yes. Known donors, someone you personally know who is willing to donate eggs, are accepted in Tammuz’s programs. They go through the same medical, genetic, and psychological screening as anonymous donors. Some intended fathers prefer this option for personal or cultural reasons.
