Question

Match the given fertilisation methods (A-H) to their respective characteristic (I-VI)
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 the gametes in the female reproductive tract
V. Transfer of the 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. ICSF
E. IUT               F. IVF
G. IUI                H. In vivo fertilisation

## CORE INFORMATION
✓ **Answer**: A
## CONCEPT FRAMEWORK
**Primary Concept**: Assisted Reproductive Technologies (ART)
**Related Topics**: Fertilization, Embryology, Reproductive Health
**Prerequisites**: Basic understanding of human reproduction and different ART procedures.
## SOLUTION PATHWAY
**Given Information**: Different fertilization methods and their characteristics.
**Method & Steps**:
1. **GIFT (Gamete Intrafallopian Transfer)**: Transfer of ovum from a donor to the oviduct of the recipient (V).
2. **ZIFT (Zygote Intrafallopian Transfer)**: Zygote or early embryo with up to 8 blastomeres is transferred into the oviduct (II).
3. **AI (Artificial Insemination)**: Fusion of gametes occurs in the female reproductive tract (IV), as sperm is artificially introduced.
4. **ICSI (Intracytoplasmic Sperm Injection)**: Sperm is directly injected into the ovum in vitro (VI).
5. **IUT (Intrauterine Transfer)**: Zygote with more than 8 blastomeres is transferred into the uterus (III).
6. **IVF (In Vitro Fertilization)**: Collected gametes are made to form the zygote in the laboratory (I).
7. **IUI (Intrauterine Insemination)**: Similar to AI, sperm is introduced into the female reproductive tract, leading to fusion of gametes there (IV).
8. **In vivo fertilization**: Natural fertilization, meaning fusion of gametes in the female reproductive tract (IV).
## OPTION ANALYSIS
[A] ✓: A - V; B - II; C - IV; D - VI; E - III; F - I; G - IV; H - IV (Correct match based on the explanations above).
[B] :x: Incorrect matches (e.g., A - I, C - III).
[C] :x: Incorrect matches (e.g., B - III, D - V).
[D] :x: Incorrect matches (e.g., A - VI, B - V).
## LEARNING AIDS
**Common Mistakes**:
1. **Confusing GIFT and ZIFT**: Remember GIFT involves gametes, while ZIFT involves zygotes.
2. **Mixing up IUI and IVF**: IUI involves insemination in the uterus, while IVF involves fertilization outside the body.
**Quick Tips**:
1. **Focus on the prefixes**: 'Intra' means within, 'Inter' means between, 'In vitro' means outside the body.
2. **Relate to the number of blastomeres**: ZIFT is up to 8 blastomeres, IUT is more than 8 blastomeres.
