A test tube baby is a child born through artificial insemination, that is, the egg or sperm were collected by a doctor and combined in an artificial manner (not through penis-vagina intercourse)
A test tube baby is a baby created to help people who have trouble conceiving naturally. An egg from the mother or donor is fertilised with a sperm cell from the father or donor and the embryo is allowed to develop until it is several cells large. At this stage modern techniques can be used to screen the embryo for genetic defects but this is not always carried out, most of the time for ethical or religious reasons or due to the expense. The embryo is then embedded into the uterus of the mother or surrogate to gestate as a normal baby would.
