Test tube baby is formed by which of the following techniques.
Test tube baby is formed by the technique of IVF followed by ET(embryo transfer).
In IVF (in vitro fertilisation), ovum from wife/donor and sperms from husband/donor are collected and are induced to form zygote in the laboratory. As fertilisation occurs outside the body it is called in vitro fertilisation. This is followed by the transfer of embryo into the female for further development.
In intra cytoplasmic sperm injection (ICSI), a tiny needle is used to inject sperm into the egg.
IUI (intra-uterine insemination) is a technique in which the semen is artificially introduced into the vagina or uterus of the female.
GIFT (gamete intra fallopian transfer) involves transfer of ovum into the female who cannot produce ovum but can provide a favourable environment for fertilisation and further development.
