which of the following processes is involved in the assisted reproductive technology known as 'GIFT'?

Options

A. Transfer of zygote into the fallopian tube
B. Transfer of zygote into the uterus
C. Transfer of ovum collected from donor to the follopian tube
D. Transfer of ovum collected from donor to the uterus

Answer

To solve the question regarding the process involved in the assisted reproductive technology known as GIFT (Gamete Intrafallopian Transfer), we can follow these steps:

### Step-by-Step Solution:

1. **Understanding GIFT**:
- GIFT stands for Gamete Intrafallopian Transfer. It is a type of assisted reproductive technology (ART) that involves the transfer of gametes (sperm and eggs) into the fallopian tubes.

2. **Analyzing the Options**:
- The options provided are:
1. Transfer of zygote into the fallopian tube
2. Transfer of zygote into the uterus
3. Transfer of ovum collected from donor to the fallopian tube
4. Transfer of ovum collected from donor to the uterus

3. **Eliminating Incorrect Options**:
- **Option 1**: Transfer of zygote into the fallopian tube is incorrect because GIFT involves the transfer of gametes (sperm and eggs), not a zygote.
- **Option 2**: Transfer of zygote into the uterus is incorrect because GIFT does not involve the uterus; it specifically targets the fallopian tubes.
- **Option 4**: Transfer of ovum collected from donor to the uterus is also incorrect for the same reason as option 2.

4. **Identifying the Correct Option**:
- **Option 3**: Transfer of ovum collected from donor to the fallopian tube is the correct answer. In GIFT, eggs (ova) are collected and then transferred to the fallopian tubes along with motile sperm for fertilization to occur in vivo.

5. **Conclusion**:
- Therefore, the correct answer is **Option 3: Transfer of ovum collected from donor to the fallopian tube**.
