Test tube baby is a term that refers to a child that is conceived outside the women’s body by a scientific process known as In-Vitro fertilization or IVF treatment. This entire process is done in a laboratory. In this process the eggs are taken from the mother’s ovary and fertilised by the sperms from the father. 

The fertilised egg is cultured for 2–6 days and allowed to divided 2-4 times inside a test tube (hence the name test tube baby) These eggs are then returned back to the mother’s uterus where it can be developed normally, this is done with the intention to establish a successful pregnancy.
