Can Two Girls Have a Baby? A Guide to LGBTQ+ Family Building in Thailand

Can two girls have a baby? This guide explains how the process works, compares the main treatment options, and walks through what you need to know about the latest legal considerations in Thailand for 2026.

Can two girls have a baby? The Short Answer

Can two girls have a baby? The short answer is yes. While two women cannot conceive naturally because conception requires sperm, many same-sex female couples successfully build their families with donor sperm and modern assisted reproductive care.

It is also worth knowing that the data on female couples using donor sperm is encouraging. A 2026 nationwide cohort study presented at ESHRE (Wang et al.) found a cumulative live birth rate of 41.1% to 43.7% after six cycles of donor insemination.

In short, the absence of a male partner does not reduce your chances of having a baby. 

Can Two Women Have a Baby Naturally?

Biologically, no. Natural conception requires an egg and a sperm. Two women cannot produce sperm, so unassisted conception is not possible.

That is the only limitation. Everything else, carrying a pregnancy, giving birth, and raising a child, is fully within reach. With donor sperm and fertility treatment, the biological barrier is bypassed entirely.

How Do Two Women Have a Baby? The Three Main Pathways

There is no single “right” way. The best option depends on your ages, your ovarian reserve, your uterine health, and how you want to share the experience of parenthood.

Option 1: Donor Sperm and IUI

If one partner has open fallopian tubes and regular ovulation, IUI (Intrauterine Insemination) is often the simplest first step. A screened donor’s sperm is washed and placed directly into the uterus around ovulation. No egg retrieval is involved.

The success rate per cycle in the ESHRE data above shows that six cycles of donor insemination produce a live birth in roughly four out of ten cases for single women and female couples.

Another 2026 ESHRE cohort study found a 52.9% cumulative live birth rate for female couples, compared with 40.9% for heterosexual couples using the same treatment.

Also, IUI is less invasive and less expensive than IVF. It is a reasonable starting point if there is no known fertility issue on the carrying partner’s side.

Option 2: Reciprocal IVF (ROPA / Shared Motherhood)

Reciprocal IVF, also called ROPA (Reception of Oocytes from Partner) or shared motherhood, allows both partners to be biologically involved. One partner provides the eggs. The other partner carries the pregnancy. In other words, the egg provider is the genetic mother. The carrying partner is the gestational mother.

The eggs are fertilized with donor sperm in the lab. The resulting embryo is transferred into the carrying partner’s uterus. This is the option most couples ask about, because it allows both partners to feel physically connected to the pregnancy.

A systematic review of 1,405 reciprocal IVF cycles shows that outcomes are comparable to those of conventional IVF using a patient’s own eggs, with live birth rates between 29% and 57% across studies.

A large multicenter cohort reports 73.7% of ROPA cycles achieve at least one live birth with all available embryos, and approximately 78.3% of couples have a baby.

The most important variable is the age of the egg provider. If she is under 35, success rates are highest. After 35, egg quality declines, and the cumulative chance of success drops accordingly.

Option 3: Standard IVF

If one partner prefers to both provide the eggs and carry the pregnancy, standard IVF is the path. The chosen partner undergoes ovarian stimulation, egg retrieval, fertilization with donor sperm, and embryo transfer. The other partner’s role is supportive rather than biological.

This is also the right choice if the egg-providing partner has a uterine condition that makes carrying difficult, or if the carrying partner has a uterine factor that needs to be addressed before transfer.

What to Consider Before Choosing Shared Motherhood

Reciprocal IVF is a coordinated medical process. It requires two healthy reproductive systems working in sequence. Before starting, a fertility specialist will assess both partners.

Fertility Assessment of The Egg Provider

The egg provider’s ovarian reserve is the single biggest factor in success. An AMH blood test and an antral follicle count will estimate how many eggs she has and how she is likely to respond to stimulation.

Age matters here: egg quality declines gradually through the 30s and more steeply after 40. The egg provider should be the partner with the stronger ovarian reserve, not necessarily the younger one, although age is usually the best proxy.

Fertility Assessment of Carrying Partner

The carrying partner’s uterus needs a healthy environment for implantation. A uterine evaluation will check for fibroids, polyps, endometriosis, or scar tissue that could interfere with embryo transfer or pregnancy. If a problem is found, it can often be treated before the cycle begins.

Embryo Screening: PGT-A 

Many couples choose PGT-A (preimplantation genetic testing for aneuploidy) to screen embryos for chromosomal abnormalities before transfer.

This is optional, but it can reduce the risk of miscarriage and is worth discussing with your specialist, especially if the egg provider is over 35.

The Emotional Dimension.

Shared motherhood sounds harmonious, and for many couples it is. But it also means negotiating who provides eggs, who carries, and how you will talk about these roles with your child and with your families.

Couples who discuss these questions openly before starting tend to feel more prepared for the emotional weight of the process.

The Legal Landscape for LGBTQ+ Fertility in Thailand (2026 Update)

Thailand’s legal framework for LGBTQ+ family building is in transition. Two separate laws matter, and they are moving at different speeds.

Marriage Equality is In Force

Thailand’s Marriage Equality Act took effect on 23 January 2025, replacing gender-specific terms like “husband” and “wife” with “spouses”. Legally married same-sex couples now have equal recognition under marriage law.

Assisted Reproduction Law has not Caught Up

The Protection for Children Born through Assisted Reproductive Technologies Act (often called the Surrogacy Protection Act) was enacted in 2015. It remains the governing statute for surrogacy and, in practice, for certain forms of reciprocal IVF.

As of 2026, it still restricts altruistic surrogacy to married heterosexual couples. Standard fertility clinics in Thailand are therefore unable to offer surrogacy or reciprocal IVF to same-sex couples under current rules.

Amendments have been proposed. A draft bill would introduce gender-neutral terminology and extend access to altruistic surrogacy to legally married same-sex couples. But the amendments have not been promulgated and remain in the legislative process.

What Does This Mean in Practice?

For IUI and standard IVF with donor sperm, the legal picture is clearer: these treatments are available, and many accredited clinics in Thailand work with female couples.

For reciprocal IVF and surrogacy, the legal position is more restrictive, and any clinic that offers them to same-sex couples is operating in a gray zone.

This is not a reason to give up on your family-building goals. It is a reason to ask direct questions about legal eligibility before you commit to a treatment plan or a clinic.

A reputable fertility center will be transparent about what it can and cannot offer under current Thai law. Ask for that clarity in writing.

Conclusion

Can two girls have a baby? Yes. Donor sperm, IUI, IVF, and reciprocal IVF have made biological family building a reality for female couples.

The first step is not choosing a treatment. It is understanding your own biology. Which partner has the stronger ovarian reserve? Does the carrying partner have a healthy uterus? What does the legal timeline look like for the specific treatment you are considering?

Our Bangkok IVF center offers fertility assessments tailored for female couples, including ovarian reserve testing, uterine evaluation, and a clear conversation about what is legally possible in Thailand right now. Book a consultation with our specialists to start with answers, not assumptions.

FAQs

1. Can two women have a baby with both of their DNA?

No. A child’s nuclear DNA comes from one egg and one sperm. In most female couples, they use donor sperm, and the carrying partner does not contribute DNA to the child.

2. Is donor sperm anonymous in Thailand?

Thai regulations require strict screening of sperm donors for genetic and infectious conditions. The level of anonymity and the amount of donor profile information available vary by clinic and by the source of the sperm.

Some couples use anonymous bank sperm; others use a known donor, which brings additional legal and emotional considerations. Discuss this with your clinic before choosing a path.
