You can sign up to donate your organs at this government website or at your state's Department of Motor Vehicles.

Organ donation isn't usually logistically possible if you die at home

Since organs need to be well-preserved for organ donation, with oxygen flowing through the body, internal organs often aren't viable for organ donation if someone dies at home. But some tissues—like eye corneas and skin tissue—may still be donated since they remain usable for a longer period without oxygen flow.

In the US, you must actively sign up to donate your organs

The US has an opt-in donation system for organ donation—meaning people must provide consent to proceed with any donation. Locations including Spain, the United Kingdom, and Argentina have an opt-out donation system, which means individuals are presumed to be donors unless they actively refuse consent.

You can sign up to donate your body to science

It's a separate process to donate your body for medical research; you usually must contact a whole-body donation program directly. Bodies can be donated for medical research, for forensic analysis research, or for medical students to work with as they learn anatomy and surgery, among other purposes. Learn more about numerous accredited organizations that provide human bodies, organs, and tissues to medical researchers and students.

'Donation after circulatory death' is on the rise

This occurs when a patient in a coma is on life support and family members agree to donate the organs. Watch this video about a 2025 New York Times investigation that identified 12 instances across nine states of bungled or premature attempts to retrieve organs from people whose families had authorized withdrawal of life support.

Brain death is a top source of organ donation

Brain death is a significant source of organ donations—approximately 40% of organs in the US and the UK are recovered from people who experience brain death. Patients declared brain dead and hooked up to intensive care unit machines will still have oxygen flowing to organs like the heart, lungs, and kidneys—preserving those organs.

Brain death is a significant source of organ donations because patients declared brain dead and hooked up to intensive care unit machines will still have oxygen flowing to organs like the heart, lungs, and kidneys—preserving those organs.

England changed to an organ donation opt-out system in May 2020

A law that went into effect in May 2020 in England changed the country's organ donation regulations, reflecting public support for organ donation. Now, adults are typically presumed to have agreed to donate their own organs upon death unless they declare they're refusing to donate organs (or their family opts them out).

Living donations most commonly involve a kidney or part of a liver

In 2023, more than 6,900 transplants were made possible thanks to living donors. Living donation is when a living person donates an organ or part of an organ—usually one of their two kidneys or part of the liver, since that organ can regenerate in a healthy person. Much more rarely, living donors donate other organs. Living donations often occur when someone wants to ensure a loved one has certainty that they will quickly receive a needed organ.

Several years after the English law changed, organ donation rates haven't improved

A 2024 analysis found that several years after England changed its organ donation system to an opt-out donation system there was no improvement to the country's organ donation rates, perhaps highlighting the need for better understanding and education around the law.

Observant Catholics can donate organs because the official Catholic stance is brain death is death—enabling organ donation

The Vatican states that brain death, when properly diagnosed, means that a person is dead even though machines can keep them alive. That official stance from Catholic leadership and echoed by most Catholic doctors and ethicists enables the families of observant Catholics to proceed with organ donation.

Donated hearts remain viable three times longer now with new tech

Advances in organ perfusion systems have significantly lengthened the amount of time donated hearts can remain viable for transplant, expanding the possibilities for donor organs to wider geographic areas. "Heart in a box" devices, developed in recent years, enable effective oxygen flow in the donor heart during transport, which means that hearts can now travel farther to potential recipients and still be in good condition.

More than 90,000 people need a kidney transplant, and kidneys can be donated by living donors since we only need one to live a normal, healthy life.

UNOS oversees the entire US organ donation system

The United Network for Organ Sharing is a private, nonprofit organization that manages much of the US organ donation and transplantation system under a federal contract. Medical urgency, blood type, organ size, and geography of the donor and recipient are all factors determining how someone who needs an organ is matched with someone who donated an organ.

Research advances suggest death takes much longer than we realized

Recent research indicates that organs, including the brain, are better at handling a lack of oxygen after the heart stops beating than previously known. Such findings may open up possibilities that include someday reversing certain death processes and expanding the availability of organs available for organ donations. (Some users may experience a paywall.)

In 2024, the US had more organ transplants than ever before—besting the 2023 record

More than 48,000 organ transplants were performed in 2024, and about 46,630 were performed in 2023. These record highs are illustrated here as part of data from 1988 to partway through 2025. Kidneys, livers, and the heart remain the most common transplanted organs. (Some users may encounter a paywall.)

Artificial intelligence may improve organ donation systems—and even organ health

Mayo Clinic transplant experts suggest that artificial intelligence could potentially improve organ donation systems in several ways, including better identifying patients most at risk for organ rejection, enhancing donor-recipient matching, and helping to avoid organ transplant needs by identifying health issues earlier.

Transplant organs don't always last a lifetime—that's where retransplants come in

How long a transplanted organ lasts depends on a variety of factors including the type of organ and the health of the recipient. Sometimes organs can last many decades, but other times people may need retransplants, which means another transplant following a previous one. Retransplants are most common with kidneys.

3 US maps illustrate transplants, donors, and organ waitlist additions—by state.

More than 40 states have passed versions of the Uniform Declaration of Death Act

The 1981 model law, now enacted in most states, is the legal basis for death in the US. There have been many efforts to amend this law, citing the need for more transparency to improve trust between families and the medical profession, though none have moved forward. Alterations to the law could have implications for organ donations and removing life support.

Transplanted organs can be rejected by the body immediately, months after transplant, or slowly over years

Organ rejection remains a huge challenge for organ transplant recipients. Rejection occurs when a recipient's immune system identifies a transplanted organ as foreign and attacks it. Recipient-donor screening processes try to match antigens to help reduce this risk.

Listen to why thousands of donated human kidneys are thrown away annually, even as thousands of people are awaiting a kidney transplant.

The first successful organ transplant was performed in 1954

The successful kidney transplant procedure, at what's now-called Brigham and and Women's Hospital, ushered in a new medical era and gave hope to patients with organ failure. The recipient, 23-year-old Richard Herrick, lived eight more years after receiving the donated organ from his living twin brother, Ronald.

Gifting money is one way to avoid death taxes

Gifting money while you're alive is one way people avoid estate and inheritance taxes. There is a yearly cap on how much you can give to a person before that money is taxed—but there isn't a cap on how many people you can give money to in a year.

Brain death is very rare—only 2% of hospital patients have brain death in the US

A peer-reviewed analysis examining US hospital billing code data from 2012 to 2016 concluded that the incidence of brain death is about 2% in the country. There was no available information indicating what proportion of those patients underwent organ donation.

Organ transplants can come with a price tag of more than $2M without insurance

According to 2025 report data that was graphically represented by Statista, average costs for organ transplants can be as steep as $2.3M for a double lung transplant and $1.9M for a heart. These figures are based on what was actually charged to insurance companies—not what individual patients paid. Following the actual transplant there are also additional costs associated with the procedure, including lifelong immunosuppressant drugs.

Which organs can you live without?

While there are some organs (such as the heart) that people simply can’t live without, there are other organs that can be removed without a huge impact. Patients who have their appendix removed, for example, experience no changes to their daily...

Brain death is a medical diagnosis without any wiggle room

Seeking to resolve long-standing variations between hospitals and state procedures, in 2023 several expert groups published comprehensive step-by-step guidance for clinicians to follow when determining brain death in kids and adults. Among other guidelines, it stated that doctors don't need to get family consent to do the tests needed to make this determination.

Read why one man agreed to get a pig kidney in 2025 to replace his own failing organ

The 68-year-old New Hampshire man told USA Today that a motivator for the experimental surgery was his belief that he was going to die anyway, and other people suffering from kidney disease could gain valuable insights. Yet the surgery bought him time—he lived 271 days with a pig organ and later received a human kidney transplant. Clinical trials began in 2026 to test the pig xenotransplants in more people.

The global xenotransplantation market may already be valued at more than $13B.

In 2023, at least 6 people were charged with stealing body parts

A recent case involving alleged trafficking in stolen human body parts charged that there was a nationwide network of individuals who bought and sold human remains. The charges alleged, among other things, that from 2018 through 2022, the manager of the morgue at Harvard Medical School's Anatomical Gifts Program stole organs and other parts of cadavers that had been donated for medical research and education. In late 2025, that Harvard morgue manager was sentenced to 96 months in prison.

If surgeons removed organs, including one of your lungs, a kidney, your spleen, appendix, tonsils, part of your liver, and even some of your reproductive organs, you could still survive.

NSF-funded research into matching algorithms improved the success of organ transplants

Investigations in game theory, including concepts focused on creating mutually beneficial partnerships—matching theory—led to the design of computer systems that efficiently matched kidney recipients and live donors, resulting in higher-quality matches. By 2019, these matching algorithms were used for multi-organ exchanges.

'Human composting' is an eco-friendly burial method legal in only a few states

Formally known as natural human organ reduction, this process relies on the same principles as standard composting and breaks down the body over many weeks, turning it into a type of soil. It's currently only legal in a handful of states.

Each second, the human body produces 2 million to 3 million new red blood cells.

White patients waited 374 days for a kidney—Black patients waited 727 days

A 2022 congressionally mandated report highlighted racial inequities in the US organ transplant system, including disparities that made it more likely white people will be placed on organ wait lists than Black people. It spotlighted inequities such as racial differences in median kidney wait times identified in earlier research. The report, from the National Academies of Sciences, Engineering, and Medicine, recommended fixes including that the Department of Health and Human Services develop national performance goals for the system and achieve equity in the system in the next five years.

Watch this video letter (via Facebook) from a kidney recipient to his donor

A kidney recipient named Justin reads a letter he wrote to his deceased donor about how the person's generous kidney donation saved his parents from having to watch him suffer and his brother from having the pressure of perhaps being his only shot at a life-saving transplant.

How much your blood really costs

In the US, donating plasma twice a week can earn you $400 a month. But this system only works by targeting people who need the money most. Plasma clinics are placed in low-income zip codes, and frequent donation may increase health risks.

In 1984, a dying infant lived for three weeks with a baboon heart inside her chest.

Cells can last in the human body from days to a person's entire life

Despite claims that a person's body replaces itself every seven to 10 years, the rate at which cells die and are replaced varies by cell type. Gastrointestinal cells that line the digestive tract and stomach last only a few days, while some heart muscle cells and most neurons are around from birth until death.

Xenotransplants are an experimental last resort for the terminally ill when they cannot or will not receive a human organ.

Immunosuppressants enable organ transplants, but come with severe side effects

This drug cocktail helps to lower your body's natural response to attack a transplanted organ. Such medications usually need to be taken for a lifetime after receiving an organ and can come with serious side effects including high blood pressure, diabetes, increased risk of some cancers, and high cholesterol, among others.

This Indiana medical school encouraged students to get to know their cadavers' families

The school's anatomy professor instructed medical students to think of the cadavers they worked with as their "first patients"—using their names to acknowledge that this was a person and to exchange letters with the cadaver's family members if they agreed to participate. At the conclusion of the course, families were invited to a lab-based memorial service.

In 1968, a Harvard Medical School committee issued the first neurological definition of death

The definition set a legal and medical precedent for how we define death, important for issues including organ donation. This 2020 video podcast discusses the history of brain death controversies and the variability in how death has been determined, including discussions in the late 1960s about when patients are considered dead in the context of organ donations.

Trusts offer ways to reduce the taxes beneficiaries pay on assets in one’s estate

People of different socioeconomic classes often decide to establish a trust to avoid certain taxes. When someone dies and leaves assets to beneficiaries in a will, those beneficiaries must pay specific taxes a trust's beneficiaries avoid. It all depends on the type of trust.

About 70% of the Human Genome Project's reference genome came from one donor

Volunteers who donated blood to the Human Genome Project consented to using no more than 10% of their DNA, raising questions about the project's legality. Listen to how pressure from a private competitor may have driven officials to ignore ethical standards.

How heart transplants work

Heart transplants require an old heart to be removed and a new one to be installed without killing the patient. How does that work? In this easy-to-understand five-minute video, learn each step of the intricate process, from donor matching to the preservative solution a heart is doused in while it is transported.

One man lived with a gene-edited pig kidney for 271 days, setting a record, before he received a human kidney.

Without the option of modern blood transfusions, some doctors in the mid-1800s tried to help save cholera patients by injecting them with cow's milk, hoping it would boost their nutrition and hydration.

Each part of the human body experiences aging differently

With global average life expectancy cresting at 73 years, understanding how the body ages is imperative to effective medical treatment and maintaining a desired quality of life. This 13-minute video dives into how the body and its organs age "from head to toe."
