Biology is weird. If you’ve ever sat in a high school health class and zoned out while a teacher pointed a laser at a plastic diagram of the reproductive system, you probably walked away with the standard "boys have this, girls have that" mindset. It’s the simple version. But nature rarely sticks to the script. When people ask do guys have a uterus, the short answer is usually no—but "usually" is doing a lot of heavy lifting there.
Honestly, the human body is more of a spectrum than a set of rigid blueprints. For the vast majority of biological males, there is no uterus. It’s just not part of the standard developmental package. However, if we’re talking about the entire breadth of human existence, including genetic variations, intersex conditions, and the realities of modern medicine, things get a lot more interesting than a basic textbook suggests.
The standard biological "no" and how it happens
For most men, the story begins about six weeks into gestation. At that point, every embryo has the potential to develop either way. We all start with two sets of ducts: the Mullerian ducts (which can become the uterus, fallopian tubes, and upper vagina) and the Wolffian ducts (which become the male internal reproductive structures).
If you have a Y chromosome, your body kicks into gear. A specific gene called SRY triggers the development of testes. Those tiny, early-stage testes then pump out something called Anti-Mullerian Hormone (AMH). It’s exactly what it sounds like. It tells the Mullerian ducts to wither away. Basically, it’s a biological "delete" button for the uterus.
But what if that button doesn’t get pressed?
When the answer is actually yes: PMDS Explained
There is a real, documented medical condition called Persistent Mullerian Duct Syndrome, or PMDS. This is a rare form of internal intersex where a person has typical male external genitalia and XY chromosomes but also possesses a uterus and fallopian tubes.
It’s not a "fake" uterus. It’s the real deal.
Usually, guys don't even know they have it until something goes wrong. Maybe they have an undescended testicle, or they develop an inguinal hernia. When a surgeon goes in to fix the hernia, they find a surprise. Imagine being a surgeon in a standard operating room and discovering a fully formed uterus inside a male patient. It happens. Dr. Peter A. Lee and other researchers in the field of pediatric endocrinology have documented these cases for decades.

It’s usually caused by one of two things:
- The body doesn't produce enough AMH.
- The body produces the hormone, but the tissues are "deaf" to it—the receptors just don't react.
In these cases, the person is raised as a guy, identifies as a guy, and looks like a guy, but internally, the "female" reproductive organs never got the memo to dissolve.
The complexity of intersex variations
We often think of "male" and "female" as two distinct islands. In reality, it’s more like a foggy coastline. Intersex is an umbrella term for people born with reproductive or sexual anatomy that doesn’t fit the typical boxes.
Take Swyer Syndrome. A person might have XY chromosomes (typically male) but appear externally female and possess a uterus. Conversely, there are people with XX chromosomes who, due to Congenital Adrenal Hyperplasia (CAH), might be born with masculine features.
Then there’s the question of the "prostatic utricle." Every guy has one. It’s a tiny, tiny pouch located in the prostate gland. Biologists often call it the uterus masculinus. While it’s not a functional uterus—it can't carry a baby and it’s about the size of a pea—it is actually derived from the same embryonic tissue that forms the uterus in females. It’s a vestigial remnant. A biological souvenir from those first few weeks in the womb.
Transgender men and the uterus
When we ask do guys have a uterus, we also have to talk about the social and medical reality of transgender men.
A trans man is a man. Many trans men are born with a uterus and choose to keep it. Some choose to have it removed through a hysterectomy. For those who keep it, the uterus remains a functional organ, even if they are on testosterone therapy. Testosterone usually stops menstruation, but the organ itself doesn't just vanish.

This leads to a lot of confusion in healthcare. A guy walks into an ER with severe abdominal pain. If the doctor assumes "men don't have uteruses," they might miss a diagnosis like endometriosis or uterine fibroids. This isn't just a theoretical debate; it’s a practical medical issue. Awareness is growing, but the medical system is still catching up to the fact that "man" and "uterus-owner" are not mutually exclusive categories.
Can a man ever get a uterus transplant?
This is the frontier. We’re already seeing successful uterus transplants in cisgender women who were born without one (Mayer-Rokitansky-Küster-Hauser syndrome). In 2014, a woman in Sweden gave birth after a transplant. Since then, dozens of babies have been born this way.
So, could a cisgender man or a transgender woman get one?
Technically, the surgery is possible. The plumbing—connecting the blood vessels—is the hard part, but surgeons are getting better at it. However, there are massive hurdles:
- Hormonal Environment: A male body doesn't naturally produce the specific cocktail of hormones (estrogen, progesterone) needed to maintain a pregnancy. These would have to be injected.
- Pelvic Shape: The male pelvis is narrower. This makes carrying a full-term pregnancy and delivering (obviously via C-section) physically risky.
- Bioethics: The medical community is currently locked in a fierce debate about whether this is "necessary" or "ethical," given the risks of organ rejection and the heavy immunosuppressant drugs required.
We aren't there yet. But the "never" is starting to look more like a "maybe, in the future."
The psychological side of the "male uterus"
For guys with PMDS, finding out you have a uterus can be a total mind-trip. Our society ties masculinity so tightly to anatomy. There’s often a fear of "losing" manhood. But doctors emphasize that having these internal structures doesn't change your hormone levels (usually) or your identity. Most men with PMDS have normal testosterone levels and can even father children, provided the uterus doesn't interfere with the sperm ducts.
It's a lesson in humility for anyone who thinks they have biology "all figured out." Nature is messy. It loves variations.

Myths that just won't die
You might have heard rumors about "male pregnancy" or guys "growing" a uterus through certain diets. Let's be real: that's nonsense.
- No, eating too much soy won't give you a uterus.
- No, there isn't a secret "male period" (though some men experience hormonal cycles).
- No, you can't "evolve" one through sheer willpower.
The presence of a uterus in a male is always either a result of an intersex condition, a surgical procedure (in the future), or because the person was assigned female at birth.
Actionable insights: What should you do?
If you're asking this because you're experiencing weird symptoms or you're curious about your own body, here are the real-world steps to take.
Check for undescended testicles. If you or a child you’re caring for has a "missing" testicle, get it checked. This is the #1 way PMDS is discovered. It’s not just about the uterus; undescended testicles have a higher risk of developing cancer if left in the abdomen.
Don't ignore pelvic pain. Guys often ignore "gut" pain, thinking it's just gas or a pulled muscle. If you have chronic, sharp pain in the lower pelvic region, an ultrasound is a simple, non-invasive way to see what's actually going on in there.
Understand the terminology. If you are a trans man, ensure your primary care provider is "trans-competent." You still need screenings like pap smears or ultrasounds if you still have your original reproductive hardware. Health is about the organs you have, not the ones people assume you have.
Be skeptical of "bro-science." The internet is full of weird claims about hormones and anatomy. Always look for peer-reviewed studies or information from reputable sources like the Journal of Pediatric Urology or The Lancet.
Biology isn't a binary; it's a vast, complicated map. While most guys don't have a uterus, the fact that some do is just another reminder of how incredibly diverse the human species really is.
