(a) IVF is a very popular method these days that is helping childless couples to bear a child. Describe the different steps that are carried out in this technique.
(b) Would you consider Gamete Intrafallopian Transfer (GIFT) as an IVF ? Give a reason in support of your answer.
a). Egg from the receiver/donor (female) and sperms from the receiver/donor (male) are collected and induced to form a zygote, in simulated conditions in the laboratory, the zygote/ early embryos(up to 8 blastomeres) then transferred into the fallopian tube(ZIFT), and embryos with more than 8 blastomeres, into the uterus(IUT) to complete its further development.
b). No, GIFT cannot be considered as an IVF technique because fertilisation takes place in the female body in vivo process.
