"Test tube baby" is a term used to describe a child conceived with the help of in vitro fertilization techniques. However, there are several synonyms for this phrase that have become more popular today. The most commonly used terms are IVF baby, assisted reproductive technology (ART) baby, or even a designer baby. These terms are more preferable since they are more precise and do not have the negative connotations of the term "test tube baby." The evolution of this terminology reflects our constantly changing perspectives on fertility and the advancements in medical science that have given rise to various methods of assisted reproductive technology.
