Organ transplantation is a medical procedure in which an organ is removed from one body and planted in the body of a recipient. It is often the only treatment for end stage organ failure, such as liver and heart failure.
Researchers have historically experimented with organ transplantation on animals and humans since the 18th century. However, the first major breakthrough was made in 1954, when the first successful kidney transplant was performed. Since then, medical breakthroughs such as tissue typing and immunosuppressant drugs have only increased the success rate of this procedure.
In Singapore, the Human Organ Transplant Act (HOTA) covers all aged 21 and above, unless one has opted out. HOTA allows for the kidneys, heart, liver and corneas to be removed for transplantation in the event of death.
