A test tube baby refers to a child conceived through In Vitro Fertilization (IVF), a process where an egg is fertilized by sperm outside the human body, typically in a laboratory setting. The term "test tube baby" is somewhat outdated and is now more accurately referred to as an "IVF baby." The procedure involves stimulating a woman's ovaries to produce multiple eggs, retrieving these eggs, and then fertilizing them with sperm in a laboratory dish. The fertilized egg, or embryo, is then transferred to the woman's uterus to develop naturally. This technology has allowed many couples facing infertility issues to conceive and have children, representing a significant advancement in reproductive medicine.
