A "Test Tube Baby" refers to a baby conceived through a process called in vitro fertilization (IVF). In this procedure, an egg is combined with sperm outside the body, typically in a laboratory dish, allowing fertilization to occur. Once the embryo develops, it is implanted into the mother's uterus, where it can grow into a baby. This method is often used by couples facing infertility issues. It has helped many people achieve their dream of parenthood. The term "test tube baby" is somewhat misleading, as the fertilization occurs in a controlled environment, not literally in a test tube.
