Q.Expand the term ZIFT.

ZIFT stands for Zygote Intra-Fallopian Transfer.

ZIFT is an assisted-reproduction technique in which a zygote formed outside the body is transferred into the fallopian tube.

ZIFT (Zygote Intra-Fallopian Transfer) is an infertility treatment technique in which ova collected from the female and sperm from the male are fertilized in vitro (in the laboratory) and the resulting zygote (or an early embryo up to the 8-celled stage) is then transferred into the fallopian tube (oviduct) of the female, allowing normal …

(a) In-vitro fertilization.

'Test tube baby' is the popular name for in-vitro fertilization, where fertilisation occurs outside the body in a laboratory dish.

In-vitro fertilization (IVF) is an assisted-reproductive technique in which an egg (ovum) retrieved from the ovary is fertilised by sperm in a laboratory culture dish ('in vitro' meaning 'in glass', outside the living body), and the resulting early embryo is then transferred into the mother's (or a surrogate's) uterus to continue development. Because fertilisation traditionally took place in a glass test tube/dish rather than inside the body, babies born this way came to be popularly called 'test tube babies'. In-situ and in-vivo fertilization both refer to fertilisation o …
