Building a family is one of the most personal decisions anyone can make. For non-binary people, it’s also a decision wrapped in an extra layer of questions – medical, legal, and emotional, that cisgender parents rarely have to think about.
How does testosterone affect fertility?
Will a birth certificate force a label that doesn’t fit?
Which clinics will treat you with respect rather than confusion?
And once a child arrives, will the law even recognize you as their parent?
The good news is that non-binary people are building families every day, through every route imaginable: carrying pregnancies, freezing eggs and sperm, using donors, working with surrogates, adopting, fostering, and co-parenting. The challenges are real, but so are the options, and so is the community of people and organizations ready to help.
This guide walks through the main routes to parenthood, the practical and medical realities, the legal landscape across Europe and beyond, and where to turn for support. Wherever you’re starting from, the goal here is the same one that gives Family By Choice its name: that family is something you get to build, deliberately and on your own terms.
A note before we begin: laws in this area are changing quickly, and they often differ from one country, sometimes one region, to the next. Treat this as an informed starting point, not legal or medical advice, and always confirm the specifics for your own situation with a qualified professional.
The routes to parenthood
There is no single “non-binary way” to build a family. What’s right for you depends on your body, your relationship situation, your finances, where you live, and what kind of connection to a child you’re hoping for.
Here are the main paths.
Carrying a pregnancy yourself
If you have a uterus and ovaries, carrying a pregnancy is a genuine option. Whether or not you’ve taken testosterone, and whether or not you identify with the word “mother.”
This is where one of the most common myths needs clearing up. Testosterone does not usually cause permanent infertility. It suppresses menstruation and ovulation for most people, which is why it should never be relied on as contraception, but many non-binary and trans people conceive after pausing it.
Clinical guidance, including the World Professional Association for Transgender Health (WPATH) is clear that testosterone must be stopped before trying to conceive and throughout pregnancy, because it can harm fetal development. Fertility can return within a few months of stopping, though timelines vary from person to person.
Carrying a pregnancy can be deeply meaningful, but it’s honest to acknowledge that it can also intensify gender dysphoria. Body changes, gendered medical language, and the assumptions of people around you can all be difficult. Many people navigate this successfully with the right support, a carefully chosen care team, and a birth plan that reflects who they are, but it’s worth going in with your eyes open.
Reciprocal IVF, IVF, and IUI
For couples where more than one partner has a uterus, reciprocal IVF (sometimes called shared motherhood or shared parenthood) is a beautiful option: one partner provides the eggs, and the other carries the pregnancy. Both partners get a physical role in bringing the child into the world, and it’s widely available across the UK, Spain, Belgium, and the Nordic countries.
IUI (intrauterine insemination) is often the simplest and least expensive starting point. Donor or partner sperm is placed directly into the uterus, timed with ovulation. IVF is more involved and more expensive: eggs are retrieved, fertilized in a lab, and an embryo is transferred. It’s frequently used when IUI hasn’t worked, when there are fertility complications, or when using frozen eggs or embryos.
Fertility preservation
If there’s any chance you’ll want a genetically related child later, fertility preservation is one of the highest-leverage steps you can take, ideally before starting gender-affirming hormones or having surgery that removes reproductive organs.
- Sperm banking is simple, quick, and relatively inexpensive.
- Egg freezing requires about two weeks of ovarian stimulation, which some people find dysphoria-inducing, but it preserves the option of a genetic child.
- Embryo freezing combines eggs and sperm (from a partner or donor) before storage.
WPATH and most endocrine guidelines recommend that everyone receive fertility-preservation counseling before starting hormones. Preservation is often still possible after pausing hormones, but earlier is generally easier.
Donor conception
Using a sperm, egg, or embryo donor opens family building to almost anyone. One crucial detail that varies dramatically by country is donor anonymity.
The UK abolished anonymous donation for donations made from April 2005 onward, meaning donor-conceived people can access identifying information about their donor at 18. The Netherlands and Sweden have similar rules. By contrast, Spain and Czechia are traditionally anonymous-donor countries, one reason they’re popular destinations for people seeking treatment abroad.
If you’re considering a known donor, a friend for instance, get a written agreement and independent legal advice before conception. Who counts as a legal parent, and who carries financial responsibility, is not always what people assume, and clarity upfront prevents heartbreak later.
Surrogacy
If you can’t or don’t wish to carry a pregnancy, surrogacy, combined with donor gametes where needed, is a route to a genetically related child. But it’s one of the most legally complicated options, and where you live matters enormously (more on that below). In gestational surrogacy, the surrogate carries an embryo that isn’t genetically hers; in traditional surrogacy, her own egg is used.
Adoption and fostering
Adoption and fostering let you build a family without a biological connection, and for many people that’s exactly the point. Single-person and same-sex adoption is legal across much of Western Europe, the UK, the US, Canada, and Australia, though experiences vary, and misgendering during assessment is unfortunately still common. Choosing an agency with a genuine track record of working with LGBTQ+ applicants makes a real difference.
Co-parenting
Not every family starts with a couple. Co-parenting arrangements, for example, a non-binary person raising a child together with a gay couple, without being romantic partners, are increasingly common, supported by dedicated matching platforms and community networks. Because parentage law rarely accommodates more than two legal parents, these families especially need thorough written agreements and legal guidance from the outset.
The medical realities
Beyond choosing a route, there are medical realities worth understanding early.
Testosterone and fertility: testosterone suppresses but doesn’t reliably eliminate fertility, isn’t contraception, and must be stopped before and during pregnancy. Many people conceive after pausing it.
Navigating gendered maternity care: obstetric and fertility care is saturated with “mother” and “women’s health” language, from intake forms to ward signage. This can be alienating. A growing number of clinics and hospital trusts, particularly in the UK and parts of Northern Europe, now offer more inclusive language, chosen-name and pronoun records, and individualized birth plans. Finding a provider with explicit trans and non-binary experience is the single best predictor of a good experience.
Chest/breastfeeding: non-binary and trans parents can often breastfeed. Those who’ve had top surgery may have reduced or no supply and can use supplementation, induced-lactation protocols, or combination feeding. Ask for a lactation consultant who’s worked with trans parents.
Mental health: pregnancy, postpartum hormonal shifts, and the stress of misgendering can raise the risk of perinatal mental-health difficulties. Trans-competent perinatal mental-health support is worth lining up in advance, not as an afterthought.
The legal landscape: recognition lags behind reality
Here is the hard truth that shapes so much of the non-binary family-building experience: in most of the world, the law that lets you change your gender and the law that decides who your child’s parents are have not caught up to each other. A country can allow you to change your legal gender marker to non-binary and still register you as “mother” on your child’s birth certificate.
The picture below reflects the situation at the time of writing. Because this area moves fast, treat it as orientation and verify current rules: ILGA-Europe’s Rainbow Map is a useful up-to-date reference for Europe, and the Movement Advancement Project (MAP) for the US.
Europe
Germany: The Self-Determination Act (Selbstbestimmungsgesetz) came into force on 1 November 2024, allowing adults to change their gender marker (including “divers” or no entry) and first name by self-declaration. But it deliberately left parentage law untouched: German law still provides that “the mother of a child is the woman who gave birth to it,” and registers the gestational parent as “mother” and a sperm provider as “father” regardless of a changed gender marker. A long-planned reform of parentage law that could have improved recognition for diverse-gender and two-mother families was not enacted before the previous government collapsed, and its future is uncertain. Germany also bans surrogacy and egg donation.
United Kingdom: Single people and same-sex couples can access licensed fertility treatment, and since 2009 both partners in a female same-sex couple can be legal parents. However, UK courts have held that a trans man who gives birth is registered as “mother,” not “father” or “parent.” In April 2025, the UK Supreme Court ruled that “woman” and “sex” in the Equality Act 2010 refer to biological sex, a decision whose full implications for healthcare and parenting are still being worked through. Altruistic surrogacy is legal; commercial surrogacy is not, and legal parenthood transfers via a parental order after birth.
France: Since the 2021 bioethics law, medically assisted reproduction is open to single women and female same-sex couples for the first time. Surrogacy remains banned.
Italy: Among the most restrictive: assisted reproduction is limited to heterosexual couples, and in October 2024 the Senate approved a law making surrogacy a “universal crime”, criminalizing it even when Italian citizens do it abroad, with prison terms and heavy fines.
Spain: Among the most open: assisted reproduction is available to single women and lesbian couples, donation is anonymous, and reciprocal IVF is common. Surrogacy is not legally recognized. A 2023 law allows gender self-determination.
Austria: Recognizes a third gender option (“divers”). Assisted reproduction is available to lesbian couples, but surrogacy and egg-donation rules are restrictive.
Czechia: IVF is legally structured around an infertile man-and-woman couple, effectively excluding same-sex couples from joint access. An expanded partnership law took effect on 1 January 2025, granting same-sex couples many — but not all — marriage-equivalent rights.
Serbia: A more conservative environment, with no recognition of same-sex partnerships, no non-binary gender category, and assisted-reproduction and adoption frameworks oriented toward heterosexual couples. Many non-binary Serbians look to treatment abroad, which makes understanding cross-border options especially important here.
The Netherlands and the Nordics: Broadly progressive. The Netherlands opens assisted reproduction to singles and same-sex couples and tolerates altruistic surrogacy case by case. Denmark, Norway, Finland, Sweden, and Iceland have self-ID or near-self-ID gender laws and broadly accessible assisted reproduction; Iceland recognizes a non-binary marker. Surrogacy is generally restricted across the region.
Ireland: The Health (Assisted Human Reproduction) Act 2024 created a comprehensive framework, including pathways for domestic altruistic surrogacy and recognition of international surrogacy — a significant step forward.
Beyond Europe
United States: Historically state-by-state, with wide variation: some states allow gender-neutral “parent” designations and X birth-certificate markers, and surrogacy is well established in states like California. In January 2025, a federal executive order directed agencies to recognize only “two sexes” and to stop issuing documents with X markers, prompting ongoing litigation. State family law and clinic access remain largely state-governed, so the picture depends heavily on where you live.
Canada and Australia: Both offer non-binary gender markers federally and in most provinces or states, and several jurisdictions allow gender-neutral parent designations. Altruistic surrogacy is legal in both; commercial surrogacy is banned.
Securing your legal parenthood
The recurring theme: don’t assume the law will recognize you automatically. Where a non-biological co-parent isn’t automatically a legal parent, common with known donors or unmarried couples, a second-parent adoption or parental order may be necessary to secure custody, inheritance, and travel rights. For surrogacy or any cross-border arrangement, specialist legal advice on how your home country will recognize the outcome is essential, especially given the bans in Germany, France, Spain, and Italy.
The emotional and practical side
The logistics are only half the story. Non-binary people building families also navigate:
- Discrimination and misgendering in waiting rooms, on forms, and in clinical conversations, consistently reported as one of the biggest sources of stress.
- Cost and insurance, which vary enormously. Some public health systems fund limited IVF cycles but with eligibility rules that can exclude single people or same-sex couples; elsewhere, treatment and fertility preservation are largely self-funded.
- Coming out as a parent, navigating family acceptance, and choosing what your child will call you – Baba, Nana, Maddy, Zaza, Parent, or something entirely your own.
None of these is a reason not to build a family. But naming them helps,,,,, because knowing a challenge is coming makes it far easier to meet.
Where to find support
You don’t have to figure this out alone. A growing network of organizations, communities, and resources exists specifically to help.
- Family Equality (US) advocacy, legal resources, and family-building guidance for LGBTQ+ families.
- LGBT Foundation (UK) trans and non-binary programs, including family support.
- Stonewall (UK) clear information on parenting rights.
- ILGA-Europe the annual Rainbow Map and country-by-country legal analysis, invaluable for checking fast-changing law.
- LGBT Mummies community and family-building support.
- Movement Advancement Project, PFLAG, and Human Rights Campaign (US) up-to-date legal maps and family resources.
- Books: Where’s the Mother? Stories from a Transgender Dad by Trevor MacDonald is a warm, honest place to start.
When choosing a clinic, look for ones that use your chosen name and pronouns on records, that have trans-specific fertility-preservation pathways, and that can point to real experience with non-binary patients.
Ask directly.
A clinic that answers those questions comfortably is one that will treat you well.
A way to think about it
If it all feels like a lot, here’s a simple sequence:
- Before any medical steps: if a genetic child might be in your future, get fertility-preservation counseling first, and bank sperm or freeze eggs or embryos. Check your country’s current law.
- Choosing a route and provider: shortlist clinics with genuine trans and non-binary experience. If using a known donor or co-parenting, get a written agreement and legal advice before conception.
- Securing legal parenthood: understand how your country records the gestational parent and whether a gender-neutral option exists. Plan a second-parent adoption or parental order where needed, and take specialist advice for any surrogacy or cross-border route.
You get to build this
Being non-binary adds real complexity to family building. There’s no point pretending otherwise. The legal system is often a step behind who you are, the medical world still speaks in gendered defaults, and the paperwork can be maddening. But every one of these obstacles has been navigated by people before you, and the map of what’s possible keeps expanding.
Your family will be exactly as real, as loving, and as legitimate as any other. Built deliberately, chosen freely, and entirely your own. That, after all, is the whole idea.
