Define test-tube baby?
Ans: In-vitro fertilisation, or IVF, is a method used by women who have blocked oviducts and are unable to conceive naturally to create a test-tube baby. For IVF (in vitro fertilisation), doctors take freshly released eggs and sperm and keep them combined for a few hours (fertilisation outside the body). The zygote is given a week to develop if fertilisation occurs before being inserted into the mother’s uterus. Like any other infant, the baby grows completely inside the uterus before being born. Test-tube babies are those born in this manner. This is a misleading term because babies cannot develop in test tubes.
