Quick Answer: What is organ donation and transplantation?
Organ donation and transplantation is the process of removing a healthy organ, or part of one, from a donor and placing it in a person whose own organ has failed. Donors can be living or deceased. Recipients take lifelong anti-rejection medicine, and full recovery from surgery often takes two to six months. [1]
What the research says
Transplants beat long-term dialysis on survival. A systematic review of 110 studies with about 1.9 million people found that most showed lower death rates, fewer heart and blood vessel events, and substantially better quality of life after a kidney transplant than on chronic dialysis. (Tonelli et al., Am J Transplant, 2011) [2]
Living kidney donation carries a small added risk. Among 96,217 U.S. living kidney donors, the 15-year risk of kidney failure was 30.8 per 10,000 donors, compared with 3.9 per 10,000 matched healthy non-donors. The authors described the absolute increase as small. (Muzaale et al., JAMA, 2014) [3]
Opt-out laws alone are not proven to raise donation. A review of 18 cross-country studies found 12 reported higher donation rates under presumed consent, but 16 had serious and 2 had critical risk of bias, so the evidence is not strong enough to call opt-out laws effective on their own. (Soria-Oliver et al., Transplantation, 2026) [4]
Key takeaways
Organ donation and transplantation involves two surgeries: one to remove the organ from the donor and one to place it in the recipient. [1]
Deceased donors can give seven organ types plus many tissues. Living donors can give one kidney, part of the liver, the uterus, bone marrow or stem cells, and rarely part of a lung or pancreas. [1]
There is no age limit for deceased donors. Living donors must be at least 18. [1]
Being a registered donor does not change the medical care you receive before or after death. [1]
The main risk for recipients is organ rejection, which is prevented with lifelong immunosuppressive medicine. [1]
What is organ donation and transplantation?
Organ donation and transplantation is the removal of a healthy organ from a donor and its placement in someone with organ failure. [1]
The process involves two surgeries that happen around the same time. One removes the organ from the donor. The other places it in the recipient. [1]
A transplant can give a second chance at life to people with life-threatening organ diseases or injuries. [1]
The need, however, is far greater than the supply. In the U.S., more than 100,000 people are waiting for an organ transplant, yet only about 48,000 transplants take place each year. [1]
What are the two types of organ donors?
The two types of organ donors are deceased donors and living donors. [1]
Deceased donor | Living donor | |
Health requirement | Organs must be in healthy condition at death | Must be in good health with no issues that affect surgery |
Who decides | Usually the donor, before death; otherwise the family | The donor, freely and in person |
Matching | National computer matching system | Blood tests and evaluations at the transplant center |
Timing | Usually within several hours of death | Surgeries are planned and scheduled |
Limits | Some diseases or infections may rule out donation | Can give only organs that are not needed to live |
A deceased donor is usually someone who recently died and chose to donate while alive. Certain diseases or infections during life may prevent donation. [1]
A living donor must be healthy and must be a "match" with the person receiving the organ. Without a match, the transplant will not work. [1]
What organs and tissues can be donated?
Seven organ types can be donated after death: the liver, kidneys, pancreas, heart, lungs, intestines, and uterus. [1]
Many tissues can also be donated after death. A smaller list can be given while you are alive.
Donated corneas are used in cornea transplants, an option for some people with corneal disease. [1]
Who can be an organ donor?
Almost everyone is a potential organ donor, and there is no age limit for deceased donors. [1]
What matters most is your overall health and the health of the organ or tissue being donated. Doctors also weigh how safe the surgeries will be. [1]
Living donors must meet stricter rules. You must be: [1]
At least 18 years old
In good physical and mental health
Aware of the process, risks, and outcomes
Volunteering freely, without pressure
A blood type match with the person you are donating to
How do you become an organ donor?
You become an organ donor after death by joining a donor registry, which gives legal consent for donation. [1]
In the U.S., you can register through: [1]
The National Donate Life Registry at registerme.org
Your state registry, listed at organdonor.gov/sign-up
Your local DMV or BMV, which can record your choice on your driver's license or ID
The Health app on an iPhone, which can send your details to the national registry
Outside the U.S., check your country's national donor registry or health ministry.
It also helps to tell your family and friends about your decision. [1]
To become a living donor, contact a transplant center that performs living donor evaluations. If you want to donate to someone you know, contact their transplant hospital directly. Screening tests come first. [1]
How does the organ donation and transplantation process work?
The organ donation and transplantation process follows six main steps, from finding a donor to the transplant surgery itself. [1]
Step | What happens (deceased donor) | What happens (living donor) |
1. Find and screen donors | Specialists review medical history and confirm the organs are viable | Many tests confirm health and match |
2. Get consent | A registered decision is honored; if none exists, the family is asked | The donor volunteers and consents |
3. Match donor to recipient | A computer system compares blood type, body size, and organs | The transplant center tests compatibility |
4. Coordinate the surgery | The recipient's team accepts the organ and books two operating rooms | The center schedules both surgeries |
5. Remove and preserve | A separate surgical team recovers the organ and preserves it | Donor surgery happens at the transplant center |
6. Transplant surgery | The recipient has surgery as soon as possible | Both surgeries happen at about the same time |
The biggest difference is speed. Deceased donation usually happens within several hours, because organs begin to break down after death. Living donation involves more planning around screening, consent, and safety. [1]
In the U.S., the Organ Procurement and Transplantation Network (OPTN) runs the national database of registered donors and waiting recipients. It also sets safety practices that most transplant centers follow for living donation. [1]
For a deceased donor, federal law requires that the surgical team recovering the organs is different from the team that cared for the donor at the end of life. The body is left in fit condition for the funeral the family chooses. [1]
Transplant surgery is complex and can take several hours. The donor and recipient stay anonymous unless they choose to share their identities. Living donors usually know who receives their organ, but they can choose anonymity too. [1]
What are the risks and benefits of organ donation and transplantation?
The main benefit of organ donation and transplantation is that it saves thousands of lives each year and helps restore quality of life. [1]
Being a registered donor carries little risk. It does not affect the care you receive before or after death in any way. [1]
For recipients, the main risk is organ rejection. Lifelong immunosuppressive medicine prevents it, but it weakens the immune system and raises the risk of infection. [1]
For kidney failure specifically, research links transplantation with lower death rates and better quality of life than staying on dialysis. [2] This matters for people living with chronic kidney disease.
For living kidney donors, a large U.S. study found a small rise in lifetime kidney failure risk compared with similar healthy people who did not donate. [3]
How long does it take to recover from organ transplant surgery?
Full recovery from organ transplant surgery takes about two to six months, for both living donors and recipients. [1]

Conclusion
Organ donation and transplantation turns one person's decision into a second chance for someone with failing organs. Deceased donors can give many organs and tissues, while healthy adults can give a kidney or part of the liver while alive.
The process is carefully regulated, from consent and matching to surgery. Donors face little risk to their own care, and recipients trade organ failure for lifelong medicine and close follow-up.
Your next step: If donation feels right for you, join your national donor registry today and tell your family about your decision. If you or someone you love is facing organ failure, ask your doctor whether a transplant evaluation makes sense, and explore our guides on kidney transplants and end-stage renal disease to prepare for that conversation.
FAQ
What is organ donation?
Organ donation is giving an organ, or part of an organ, to someone who needs it to live. Donation can happen after death if you are a registered donor, and some organs can be donated while you are still alive.
Who can be an organ donor?
Almost everyone is a potential organ donor, and there is no age limit for deceased donors. Eligibility depends mostly on your overall health and the health of the organ or tissue being donated.
Can I donate an organ while I am alive?
Yes, healthy adults aged 18 or older can donate one kidney, part of the liver, the uterus, or bone marrow or stem cells while alive. Donating part of a lung or pancreas is possible but rare.
Does being a registered organ donor affect my medical care?
No, being a registered organ donor does not affect the care you receive before or after death in any way. By law, the team that recovers organs is separate from the team that cared for you.
Will organ donation affect funeral plans?
No, organ donation leaves the donor's body in fit condition for the funeral of the family's choice. Organs are recovered in a respectful, formal surgical procedure.
How long does recovery from organ transplant surgery take?
Full recovery from organ transplant surgery usually takes two to six months for both donors and recipients. Most people stay in the hospital for days to weeks and need a month or two off work.
What is the biggest risk after an organ transplant?
Organ rejection is the biggest risk after an organ transplant. Recipients take immunosuppressive medicine for life to prevent rejection, which also raises the risk of infections.
How do I register as an organ donor?
Registering as an organ donor means joining a national or state donor registry, which gives legal consent for donation after death. In the U.S., you can register online, at the DMV or BMV, or through the iPhone Health app.
Can you be an organ donor if you have a medical condition?
Often yes. Having a medical condition does not automatically rule you out, because doctors decide which organs can be used at the time of donation.
Does your family need to agree to organ donation?
If you are on a donor registry, that is legal consent in the United States. Telling your family your wishes still helps them support your decision.
