In assisted reproductive technology, the method in which a sperm is directly injected into ovum is called
The correct option is D ICSI
A. Ovum from
donor female and sperm from donor male are fertilized in laboratory. The
zygote(upto 8 blastomeres stage) then transferred to fallopian tube called zygote
intra fallopian transfer or ZIFT.
B. ICSI- Intra cytoplasmic sperm injection (ICSI)
is a specialized technique to form an embryo in the laboratory in which a sperm is directly
injected into the ovum placed in a nutrient broth.
C. GIFT- Gamete intra fallopian transfer method is used in females who
cannot produce ova but can provide suitable envoirnment for fertilization and
further development of embryo in the oviducts. In such cases, ovum from the
donor female is surgically removed and is then introduced into the fallopian
tube of such females.
D. ET-In vitro fertilization is
a method in which fertilization of male gamete (spermatozoon) and female gamete
(ovum) outside the body in almost similar conditions as that in the body
followed by zygote or embryo transfer(ET).
So, the correct answer is 'ICSI'.
