Genital Transplants: Is Science Going Too Far, Too Fast?
Thanks to the remarkable evolution of organ transplantation, it's now possible to replace genitals that don't work properly or have been injured. Surgeons have been transplanting ovarian tissue for more than a decade, and they're now successfully transplanting penises and wombs too.
Rules and regulations aren't keeping up with the rapid rise of genital transplants.
Earlier this year, an American soldier whose genitals were injured by a bomb in Afghanistan received the first-ever transplant of a penis and scrotum at Johns Hopkins Medicine.
Rules and regulations aren't keeping up with the rapid rise of genital transplants, however, and there's no consensus about how society should handle a long list of difficult and delicate questions.
Are these expensive transplants worth the risk when other alternatives exist? Should men, famously obsessed with their penises, be able to ask for a better model simply because they want one? And what happens when transplant technology further muddles the concept of biological parenthood?
"We need to remember that the human body is not a machine with interchangeable parts," says bioethicist Craig M. Klugman of DePaul University. "These are complicated, difficult and potentially dangerous surgeries. And they require deep consideration on a physical, psychological, spiritual, and financial level."
From Extra Testicles to Replacement Penises
Tinkering with human genitalia -- especially the male variety -- is hardly a new phenomenon. A French surgeon created artificial penises for injured soldiers in the 16th century. And a bizarre implant craze swept the U.S. in the 1930s when a quack physician convinced men that, quite literally, the more testicles the merrier – and if the human variety wasn't available, then ones from goats would have to do.
Now we're more sophisticated. Modern genital transplants are designed to do two things: Treat infertility (in women) and restore the appearance and function of genitals (in men).
In women, surgeons have successfully transplanted ovarian tissue from one woman to another since the mid-2000s, when an Alabama woman gave birth after getting a transplant from her identical twin sister. Last year, for the first time in the U.S., a young woman gave birth after getting a uterus transplant from a living donor.
"Where do you draw the line? Is pregnancy a privilege? Is it a right?"
As for men, surgeons in the U.S. and South Africa have successfully transplanted penises from dead men into four men whose genitals were injured by a botched circumcision, penile cancer or a wartime injury. One man reportedly fathered a child after the procedure.
The Johns Hopkins procedure was the first to include a scrotum. Testicles, however, were not transplanted due to ethical concerns. Surgeons have successfully transplanted testicles from man-to-man in the past, but this procedure isn't performed because the testes would produce sperm with the donor's DNA. As a result, the recipient could father a baby who is genetically related to the donor.
Are Transplants Worth the Expense and Risk?
Genital transplants are not simple procedures. They're extremely expensive, with a uterus transplant estimated to cost as much as $250,000. They're dangerous, since patients typically must take powerful drugs to keep their immune systems from rejecting their new organs. And they're not medically necessary. All have alternatives that are much less risky and costly.
Dr. Hiten D. Patel, a urologist at Johns Hopkins University, believes these types of factors make penis transplants unnecessary. As he wrote in a 2018 commentary in the journal European Urology, "What in the world are we doing?"
There are similar questions about female genital transplants, which allow infertile women to become pregnant instead of turning to alternatives like adoption or surrogacy. "This is not a life-saving transplant. A woman can very well live without a uterus," says McGill University's Dr. Jacques Balayla, who studies uterine transplantation. "Where do you draw the line? Is pregnancy a privilege? Is it a right? You don't want to cause harm to an individual unless there's an absolute need for the procedure."
But Johns Hopkins urologist Dr. Arthur L. Burnett II, who served on the surgical team that performed the penis-and-scrotum procedure, says penis transplants can be appropriate when other alternatives – like a "neophallus" created from forearm skin and tissue – aren't feasible.
It's also important to "restore normalcy," he says. "We want someone to be able to have sense of male adequacy and a normal sense of bodily well-being on both physical and psychological levels."
Surgical team members who performed the penis transplant, including W. P. Andrew Lee, director of the department of plastic and reconstructive surgery, center.
As for the anonymous recipient, he's reportedly doing "very well" five months after the transplant. An update on Johns Hopkins' website states that "he has normal urinary functions and is beginning to regain sensation in the transplanted tissues."
When the Organ Donors Do It Live
Some peculiar messages reached Burnett's desk after his institution announced it would begin performing penis transplants. Several men wanted to donate their own organs. But for now, transplanted penises are only coming from dead donors whose next of kin have approved the donation.
Burnett doesn't expect live donors to enter the penis transplant picture. But there are no guidelines or policies to stop surgeons from transplanting a penis from a live donor or, for that matter, a testicle.
Live women have already donated wombs and ovarian tissue, forcing them to face their own risks from transplant surgery. "You're putting the donor at risk because she has to undergo pretty expensive surgery for a procedure that is not technically lifesaving," McGill University's Balayla says.
When it comes to uterus transplants, the risk spreads even beyond donor and recipient. Balayla notes there's a third person in the equation: The fetus. "Immunosuppressant medication may harm the baby, and you're feeding the baby with a [uterine] blood vessel that's not natural, held together by stitches," he says.
It's up to each medical institution that performs the procedures to set its own policies.
Bioethicists are talking about other issues raised by genital transplants: How should operations for transgender people fit in? Should men be able to get penis transplants for purely cosmetic reasons? And then there's the looming question of genetic parenthood.
It's up to each medical institution that performs the procedures to set its own policies.
Let's say a woman gets a transplant of ovarian tissue, a man gets a testicle transplant, and they have a baby the old-fashioned way.* The child would be genetically linked to the donors, not the parents who conceived him or her.
Call this a full-employment act not just for bioethicists but theologians too. "Catholicism is generally against reproductive technologies because it removes God from the nature of the procreative act. This technology, though, could result in conception through the natural act. Would their concern remain?" DePaul University's Klugman asked. "Judaism is concerned with knowing a child's parentage, would a child from transplanted testes be the child of the donor or the recipient? Would an act of coitus with a transplanted penis be adultery?"
Yikes. Maybe it's time for the medical field or the law to step in to determine what genital transplants surgeons can and can't -- or shouldn't -- do.
So far, however, only uterus transplants have guidelines in place. Otherwise, it's up to each medical institution that performs the procedures to set its own policies.
"I don't know if the medical establishment is in the position to do the best job of self-regulation," says Lisa Campo-Engelstein, a bioethicist with Albany Medical College. "Reproductive medicine in this country is a huge for-profit industry. There's a possibility of exploitation if we leave this to for-profit fertility companies."
And, as bioethicist Klugman notes, guidelines "aren't laws, and people can and do violate them with no effect."
He doesn't think laws are the solution to the ethical issues raised by genital transplants either. Still, he says, "we do need a national conversation on these topics to help provide guidance for doctors and patients."

Last week, researchers at the University of Oxford announced that they have received funding to create a brand new way of preventing ovarian cancer: A vaccine. The vaccine, known as OvarianVax, will teach the immune system to recognize and destroy mutated cells—one of the earliest indicators of ovarian cancer.
Understanding Ovarian Cancer
Despite advancements in medical research and treatment protocols over the last few decades, ovarian cancer still poses a significant threat to women’s health. In the United States alone, more than 12,0000 women die of ovarian cancer each year, and only about half of women diagnosed with ovarian cancer survive five or more years past diagnosis. Unlike cervical cancer, there is no routine screening for ovarian cancer, so it often goes undetected until it has reached advanced stages. Additionally, the primary symptoms of ovarian cancer—frequent urination, bloating, loss of appetite, and abdominal pain—can often be mistaken for other non-cancerous conditions, delaying treatment.
An American woman has roughly a one percent chance of developing ovarian cancer throughout her lifetime. However, these odds increase significantly if she has inherited mutations in the BRCA1 or BRCA2 genes. Women who carry these mutations face a 46% lifetime risk for ovarian and breast cancers.
An Unlikely Solution
To address this escalating health concern, the organization Cancer Research UK has invested £600,000 over the next three years in research aimed at creating a vaccine, which would destroy cancerous cells before they have a chance to develop any further.
Researchers at the University of Oxford are at the forefront of this initiative. With funding from Cancer Research UK, scientists will use tissue samples from the ovaries and fallopian tubes of patients currently battling ovarian cancer. Using these samples, University of Oxford scientists will create a vaccine to recognize certain proteins on the surface of ovarian cancer cells known as tumor-associated antigens. The vaccine will then train that person’s immune system to recognize the cancer markers and destroy them.
The next step
Once developed, the vaccine will first be tested in patients with the disease, to see if their ovarian tumors will shrink or disappear. Then, the vaccine will be tested in women with the BRCA1 or BRCA2 mutations as well as women in the general population without genetic mutations, to see whether the vaccine can prevent the cancer altogether.
While the vaccine still has “a long way to go,” according to Professor Ahmed Ahmed, Director of Oxford University’s ovarian cancer cell laboratory, he is “optimistic” about the results.
“We need better strategies to prevent ovarian cancer,” said Ahmed in a press release from the University of Oxford. “Currently, women with BRCA1/2 mutations are offered surgery which prevents cancer but robs them of the chance to have children afterward.
Teaching the immune system to recognize the very early signs of cancer is a tough challenge. But we now have highly sophisticated tools which give us real insights into how the immune system recognizes ovarian cancer. OvarianVax could offer the solution.”
How sharing, hearing, and remembering positive stories can help shape our brains for the better
Across cultures and through millennia, human beings have always told stories. Whether it’s a group of boy scouts around a campfire sharing ghost stories or the paleolithic Cro-Magnons etching pictures of bison on cave walls, researchers believe that storytelling has been universal to human beings since the development of language.
But storytelling was more than just a way for our ancestors to pass the time. Researchers believe that storytelling served an important evolutionary purpose, helping humans learn empathy, share important information (such as where predators were or what berries were safe to eat), as well as strengthen social bonds. Quite literally, storytelling has made it possible for the human race to survive.
Today, neuroscientists are discovering that storytelling is just as important now as it was millions of years ago. Particularly in sharing positive stories, humans can more easily form relational bonds, develop a more flexible perspective, and actually grow new brain circuitry that helps us survive. Here’s how.
How sharing stories positively impacts the brain
When human beings share stories, it increases the levels of certain neurochemicals in the brain, neuroscientists have found. In a 2021 study published in Proceedings of the National Academy of Sciences (PNAS), Swedish researchers found that simply hearing a story could make hospitalized children feel better, compared to other hospitalized children who played a riddle game for the same amount of time. In their research, children in the intensive care unit who heard stories for just 30 minutes had higher levels of oxytocin, a hormone that promotes positive feelings and is linked to relaxation, trust, social connectedness, and overall psychological stability. Furthermore, the same children showed lower levels of cortisol, a hormone associated with stress. Afterward, the group of children who heard stories tended to describe their hospital experiences more positively, and even reported lower levels of pain.
Annie Brewster, MD, knows the positive effect of storytelling from personal experience. An assistant professor at Harvard Medical School and the author of The Healing Power of Storytelling: Using Personal Narrative to Navigate Illness, Trauma, and Loss, Brewster started sharing her personal experience with chronic illness after being diagnosed with multiple sclerosis in 2001. In doing so, Brewster says it has enabled her to accept her diagnosis and integrate it into her identity. Brewster believes so much in the power of hearing and sharing stories that in 2013 she founded Health Story Collaborative, a forum for others to share their mental and physical health challenges.“I wanted to hear stories of people who had found ways to move forward in positive ways, in spite of health challenges,” Brewster said. In doing so, Brewster believes people with chronic conditions can “move closer to self-acceptance and self-love.”
While hearing and sharing positive stories has been shown to increase oxytocin and other “feel good” chemicals, simply remembering a positive story has an effect on our brains as well. Mark Hoelterhoff, PhD, a lecturer in clinical psychology at the University of Edinburgh, recalling and “savoring” a positive story, thought, or feedback “begins to create new brain circuitry—a new neural network that’s geared toward looking for the positive,” he says. Over time, other research shows, savoring positive stories or thoughts can literally change the shape of your brain, hard-wiring someone to see things in a more positive light.How stories can change your behavior
In 2009, Paul Zak, PhD, a neuroscientist and professor at Claremont Graduate University, set out to measure how storytelling can actually change human behavior for the better. In his study, Zak wanted to measure the behavioral effects of oxytocin, and did this by showing test subjects two short video clips designed to elicit an emotional response.
In the first video they showed the study participants, a father spoke to the camera about his two-year-old son, Ben, who had been diagnosed with terminal brain cancer. The father told the audience that he struggled to connect with and enjoy Ben, as Ben had only a few months left to live. In the end, the father finds the strength to stay emotionally connected to his son until he dies.
The second video clip, however, was much less emotional. In that clip, the same father and son are shown spending the day at the zoo. Ben is only suggested to have cancer (he is bald from chemotherapy and referred to as a ‘miracle’, but the cancer isn’t mentioned directly). The second story lacked the dramatic narrative arc of the first video.
Zak’s team took blood before and after the participants watched one of the two videos and found that the first story increased the viewers’ cortisol and oxytocin, suggesting that they felt distress over the boy’s diagnosis and empathy toward the boy and his father. The second narrative, however, didn’t increase oxytocin or cortisol at all.
But Zak took the experiment a step further. After the movie clips, his team gave the study participants a chance to share money with a stranger in the lab. The participants who had an increase in cortisol and oxytocin were more likely to donate money generously. The participants who had increased cortisol and oxytocin were also more likely to donate money to a charity that works with children who are ill. Zak also found that the amount of oxytocin that was released was correlated with how much money people felt comfortable giving—in other words, the more oxytocin that was released, the more generous they felt, and the more money they donated.
How storytelling strengthens our bond with others
Sharing, hearing, and remembering stories can be a powerful tool for social change–not only in the way it changes our brain and our behavior, but also because it can positively affect our relationships with other people
Emotional stimulation from telling stories, writes Zak, is the foundation for empathy, and empathy strengthens our relationships with other people. “By knowing someone’s story—where they come from, what they do, and who you might know in common—relationships with strangers are formed.”
But why are these relationships important for humanity? Because human beings can use storytelling to build empathy and form relationships, it enables them to “engage in the kinds of large-scale cooperation that builds massive bridges and sends humans into space,” says Zak.
Storytelling, Zak found, and the oxytocin release that follows, also makes people more sensitive to social cues. This sensitivity not only motivates us to form relationships, but also to engage with other people and offer help, particularly if the other person seems to need help.
But as Zak found in his experiments, the type of storytelling matters when it comes to affecting relationships. Where Zak found that storytelling with a dramatic arc helps release oxytocin and cortisol, enabling people to feel more empathic and generous, other researchers have found that sharing happy stories allows for greater closeness between individuals and speakers. A group of Chinese researchers found that, compared to emotionally-neutral stories, happy stories were more “emotionally contagious.” Test subjects who heard happy stories had greater activation in certain areas of their brains, experienced more significant, positive changes in their mood, and felt a greater sense of closeness between themselves and the speaker.
“This finding suggests that when individuals are happy, they become less self-focused and then feel more intimate with others,” the authors of the study wrote. “Therefore, sharing happiness could strengthen interpersonal bonding.” The researchers went on to say that this could lead to developing better social networks, receiving more social support, and leading more successful social lives.
Since the start of the COVID pandemic, social isolation, loneliness, and resulting mental health issues have only gotten worse. In light of this, it’s safe to say that hearing, sharing, and remembering stories isn’t just something we can do for entertainment. Storytelling has always been central to the human experience, and now more than ever it’s become something crucial for our survival.
