In vitro fertilisation
In vitro fertilisation
In vitro fertilisation (IVF) is a process of fertilisation where an egg is combined with sperm outside the body, in vitro (in glass). The process involves monitoring and stimulating a woman's ovulatory process, removing an ovum or ova (egg or eggs) from the woman's ovaries, and letting sperm fertilise them in a liquid in a laboratory. The fertilised egg (zygote) undergoes embryo growth for 2–6 days, and is then transferred to the same or another woman's uterus, with the intention of establishing a successful pregnancy.
Pronunciation
In vitro fertilisation: /ɪn ˈviːtroʊ ˌfɜːrtɪlɪˈzeɪʃən/
Etymology
The term "in vitro", from the Latin meaning "in glass", is used because early biological experiments involving cultivation of tissues outside the living organism were carried out in glass containers, such as beakers, test tubes, or petri dishes.
