A scientist carefully holds a test-tube baby in a laboratory incubator.

Definition

Noun: 1. A baby conceived through in vitro fertilization (IVF): A human infant conceived by the fertilization of an egg with sperm outside the mother's body, typically in a laboratory dish. The resulting embryo is then transferred to the mother's (or a gestational carrier's) uterus to develop. * Conceptual Focus: The term emphasizes the initial stage of conception occurring in an artificial, controlled environment ("test-tube" is a historical reference to laboratory glassware), rather than inside the fallopian tubes.

Examples of Usage

• Noun:
  • Louise Brown, born in 1978, was the world's first test-tube baby.
  • The development of IVF technology has helped millions of couples have test-tube babies.
  • The article discussed the ethical debates that surrounded the first generation of test-tube babies.

  • The process itself is called Assisted Reproductive Technology (ART).
• The phrase can be used metaphorically to describe something created or developed in a highly controlled, artificial, or laboratory-like setting.
  • The new policy was a test-tube baby of the committee, developed in isolation from public opinion.

Variants and Related Words

• Assisted Reproductive Technology (ART) (n): The umbrella term for all fertility treatments involving the handling of eggs and sperm.
