Anyone can donate organs, regardless of age, medical condition, or sexual orientation. There is no strict age limit for organ donation. To donate organs after death, a person generally must die in a hospital under specific circumstances, and medical professionals will determine if the organs are suitable for transplantation based on health, medical history, and other factors. Certain conditions, such as active cancer or transmissible infections, can prevent donation, but many illnesses do not rule out the possibility. Living donation is also possible for some organs, typically from close relatives or others with a personal connection, after thorough health assessment to ensure the donor's safety. Children can also be registered to donate with parental consent in some regions. The key for donation after death is that death must be confirmed, often by brain death criteria, to ensure ethical and medical standards are met. In summary, the eligibility is broad, including almost anyone who wishes to become a donor and meets medical suitability at the time of donation. Registration with an organ donor register and discussing donations with family are important steps to enable donation.
