NEET Zoology Reproductive Health Questions Solved


Match the ARTs with their description:

I. Collected gametes are made to form the zygote in the laboratory.

II. Zygote or early embryo with upto 8 blastomeres is transferred into the oviduct.

III. Zygote with more than 8 blastomeres is transferred into the uterus.

IV. Fusion of gametes within the female.

V. Transfer of ovum from a donor to the oviduct of the recipient.

VI. Sperm is injected into the ovum in-vitro.

A. GIFT

B. ZIFT

C. AI

D. ICSI

E. IUT

F. IVF

G. IUI

H. In-vivo fertilization

(3)

A. Transfer of an ovum collected from a donor into the fallopian tube (GIFT – gamete intra fallopian transfer) of another female who cannot produce one, but can provide suitable environment for fertilisation and further development.

B. The zygote or early embryos (with upto 8 blastomeres) could then be transferred into the fallopian tube (ZIFT–zygote intra fallopian transfer).

C. Infertility cases either due to inability of the male partner to inseminate the female or due to very low sperm counts in the ejaculates, could be corrected by artificial insemination (AI) technique.

D. Intra cytoplasmic sperm injection (ICSI) is another specialised procedure to form an embryo in the laboratory in which a sperm is directly injected into the ovum.

E. Embryos with more than 8 blastomeres, into the uterus (IUT – intra uterine transfer), to complete its further development.

F. In vitro fertilisation (IVF–fertilisation outside the body in almost similar conditions as that in the body).

G. The semen collected either from the husband or a healthy donor is artificially introduced either into the vagina or into the uterus (IUI – intra-uterine insemination) of the female.

H. Embryos formed by in-vivo fertilisation (fusion of gametes within the female) also could be used for such transfer to assist those females who cannot conceive.
