It is the question that keeps search engines busy and sparks late-night debates in biology classrooms. People want to know: can a woman get a woman pregnant? If we are talking about unassisted, "old-school" biological mechanics between two cisgender women, the short answer is no. You need a sperm and an egg. Currently, nature hasn't figured out a way for two human eggs to fuse and create a viable person on their own.
But that is barely scratching the surface.
The reality of 2026 is way more complex than a simple "no." When you look at the intersection of transgender health, advanced IVF techniques, and the cutting-edge world of IVG (in vitro gametogenesis), the lines start to blur. It’s not just about what happens in a bedroom; it’s about what is happening in high-end labs in places like Kyoto and San Francisco.
The basic biological "why" behind the barrier
To understand why a woman can't get another woman pregnant naturally, you have to look at genomic imprinting. It’s a bit of a genetic "lock and key" system. Even if you managed to get two eggs to merge—a process called parthenogenesis—the embryo wouldn't survive. Why? Because certain genes are only "turned on" if they come from a father, and others only work if they come from a mother.
Without a set of DNA from a biological male, the placenta won't develop correctly. The embryo simply stops growing.
Nature likes its rules.
However, the definition of "woman" isn't a monolith in medical science. If we are talking about a trans woman who has not undergone bottom surgery and still produces viable sperm, then yes, she can absolutely get her female partner pregnant through intercourse. This happens every day. It’s a vital piece of the puzzle that often gets ignored in these conversations because people get hung up on terminology rather than biology.
Reciprocal IVF: Sharing the pregnancy
For many lesbian couples, the question of "can a woman get a woman pregnant" is answered through a process called Reciprocal IVF. It’s honestly the closest thing we have to both women being physically involved in the creation of the baby.
Here is how it basically works:
One woman provides the eggs. These are harvested after a round of hormone injections. Those eggs are then fertilized in a lab with donor sperm. Once an embryo forms, it is transferred into the other woman’s uterus.

One provides the genetics. The other provides the womb.
It’s a beautiful, albeit expensive, way to bridge the gap. According to data from SART (Society for Assisted Reproductive Technology), the success rates for this are generally high, especially if the egg donor is under 35. It makes both partners feel "pregnant" in a sense—one is the genetic mother, and the other is the gestational mother.
The future: Making sperm from skin cells
Now, let's talk about the sci-fi stuff that is actually becoming real. Researchers are working on something called In Vitro Gametogenesis (IVG).
Imagine taking a piece of skin from a woman, "reprogramming" those cells into stem cells, and then coaxing those stem cells to become sperm. If this works in humans—and it has already worked in mice—it would mean two biological women could have a child that is 100% genetically theirs. No donor needed.
Dr. Katsuhiko Hayashi at Osaka University has been a pioneer in this. In 2023, his team created baby mice from two male parents. While doing the reverse (creating sperm from female cells) is slightly trickier because women lack the Y chromosome, many scientists believe it is a matter of "when," not "if."
The technical hurdles are massive.
The ethical debates are even bigger.
But honestly? The science is moving faster than the laws. We are looking at a future where the traditional requirements for conception are effectively bypassed by cellular engineering.
Transgender identity and reproductive reality
We have to be specific here. In the context of the question can a woman get a woman pregnant, we must acknowledge the lived experience of transgender women.

A trans woman who has opted to freeze her sperm before transitioning can later use that sperm to impregnate a female partner via IUI or IVF. Or, as mentioned earlier, if she hasn't started HRT (Hormone Replacement Therapy) or has paused it, natural conception is a possibility.
Many people get confused because they conflate gender identity with reproductive hardware. But in a clinical setting, doctors look at the "gametes." If one partner provides a sperm and the other an egg, pregnancy is on the table, regardless of how those individuals identify or present to the world.
Where we stand with "BPA" and Artificial Gametes
You might have heard rumors about "bone marrow sperm." About 15-20 years ago, there was a lot of hype about scientists turning bone marrow stem cells into sperm-like cells.
It didn't really pan out as a mainstream treatment.
The cells they created were immature. They couldn't actually fertilize an egg. It was a classic case of the media getting ahead of the peer-reviewed results. While that specific path hit a dead end, it paved the way for the IVG research we see today.
Today’s research focuses more on epigenetic remodeling. This is the process of stripping the "tags" off a cell to make it act like a different cell. It’s incredibly delicate work. If you mess up the imprinting, you end up with severe developmental disorders. That is why human trials are still a long way off. Nobody wants to be the first scientist to create a human life that has a built-in genetic catastrophe.
Cost and Accessibility: The elephant in the room
If you are a woman looking to get pregnant with another woman, you are likely looking at the following options and their respective price tags:
- Intrauterine Insemination (IUI): This is the "turkey baster" method's professional cousin. You buy donor sperm, track ovulation, and a doctor places the sperm directly in the uterus. It's usually $500 to $2,000 per attempt, plus the cost of the sperm ($1,000+ per vial).
- Standard IVF: Using donor sperm to fertilize your own eggs. This is much pricier, often hitting $15,000 to $25,000.
- Reciprocal IVF: The shared journey mentioned earlier. Because it involves two patients (one for egg retrieval, one for transfer), it can easily top $30,000.
It’s expensive to bypass biology.

Insurance coverage is a total wildcard. Some states in the US have "infertility mandates," but many of those laws were written with heterosexual couples in mind (defining infertility as "failing to conceive after 12 months of unprotected sex"). If you're in a same-sex relationship, you might have to pay for several rounds of IUI out of pocket just to "prove" you are infertile before insurance kicks in. It's a frustrating, systemic hurdle that many couples face.
The bottom line on current possibilities
So, can a woman get a woman pregnant?
If you mean "naturally, through the exchange of female fluids," then the answer remains a firm no. There is no documented case of human parthenogenesis resulting in a live birth.
If you mean "can two women be the sole biological parents of a child," we are in a waiting room. The technology is being perfected in labs, but it is not available to the public yet.
If you mean "can a woman who produces sperm get a woman who produces eggs pregnant," then the answer is yes, absolutely.
Actionable steps for couples looking to conceive
If you and your partner are exploring how to start a family, don't just rely on Google. The landscape changes fast.
- Get a fertility workup early. Even if you aren't ready yet, knowing your AMH levels (egg reserve) helps you plan.
- Consult a reproductive endocrinologist (RE). Look for one who specifically advertises "LGBTQ+ family building." They will be familiar with the legal and medical nuances of donor sperm and reciprocal IVF.
- Check the legal status of parentage in your state or country. In some places, the woman who doesn't carry the baby needs to perform a "second-parent adoption" to have legal rights, even if you’re married.
- Look into sperm banks. Reputable banks like California Cryobank or Seattle Sperm Bank provide detailed donor histories, which is crucial for screening genetic disorders.
- Stay updated on IVG trials. While not ready for the clinic, following the work of institutions like the Gladstone Institutes will keep you informed on when "two-mom genetics" might finally become a reality.
The dream of two women creating a baby together is no longer a "never." It's a "not yet." Until then, we have incredible medical interventions that make motherhood more accessible than it has ever been in human history.
