| 1. | IVF | 2. | GIFT |
| 3. | IUI | 4. | IUD |
| 1. | To introduce genetic material from another species. |
| 2. | To overcome infertility due to low sperm motility. |
| 3. | To stimulate multiple ovulations. |
| 4. | To prevent sexually transmitted diseases. |
A childless couple can be assisted to have a child through a technique called GIFT. The full form of this technique is?
1. Gamete Inseminated Fallopian Transfer
2. Gamete Intra Fallopian Transfer
3. Gamete Internal Fertilisation and Transfer
4. Germ Cell Internal Transfer
In ‘test – tube baby’ procedure:
| 1. | Fertilization is in-vitro but embryo development is in-vivo |
| 2. | Fertilization is in-vivo but embryo development is in-vitro |
| 3. | Both fertilization and embryo development are in-vitro |
| 4. | Both fertilization and embryo development are in-vivo |
In ZIFT:
| 1. | zygote or early embryos (with up to 8 blastomeres) are transferred into the fallopian tube |
| 2. | embryos with more than 8 blastomeres are transferred into the uterus |
| 3. | ovum collected from a donor is transferred into the fallopian tube of the recipient |
| 4. | semen is artificially deposited in the uterus |
| 1. | GIFT involves transferring gametes into the fallopian tube, ZIFT involves transferring zygotes into the fallopian tube. |
| 2. | GIFT involves transferring zygotes into the uterus, ZIFT involves transferring gametes into the uterus. |
| 3. | GIFT and ZIFT, both involve transferring embryos into the uterus at different stages. |
| 4. | There is no difference; GIFT and ZIFT are the same procedures. |
