Answer:
IVF refers to in vitro fertilization and ET
refers to embryo transfer. Gametes from the male and female are collected
hygienically and induced to fuse in the laboratory set up under simulated
conditions.
The zygote formed is collected and is
introduced into the uterus of a host or surrogate mother at an appropriate time
(secretory phase). Early embryos (up to 8 cell) are generally transferred to
the Fallopian tube whereas embryos with more than 8 cells are transferred to the
uterus.
