体外人工受孕（英语：In vitro fertilization，缩写IVF）又称人工受孕（artificial fertilization），是将卵子与精子取出，在人为操作下进行体外受精，并培养成胚胎，再将胚胎植回母体内，整个过**正在试管内的时间只有 2－6 天而已。以目前的技术，尚无法在体外将胚胎培养至足月。利用体外受精技术生产出来的婴儿称为试管婴儿（Test tube baby）。

In vitro fertilisation (or fertilization; IVF) is a process by which an egg is fertilised by 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) is cultured for 2–6 days in a growth medium and is then implanted in the same or another woman's uterus, with the intention of establishing a successful pregnancy.
