In which technique, the donor's semen is artificially introduced into the female uterus?

Options

A. Intravaginal insemination
B. Intrauterine insemination
C. Intarcytoplasmic sperm injection
D. Gamete intra Falloopian transfer

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for the technique in which donor semen is artificially introduced into the female uterus.

2. **Reviewing the Options**: The options provided are:
- A) Intra-vaginal insemination
- B) Intra-uterine insemination
- C) Intra-cytoplasmic sperm injection
- D) Gametes intra-fallopian transfer

3. **Analyzing Each Option**:
- **Option A: Intra-vaginal insemination**: In this technique, semen is introduced into the vagina, not the uterus. Therefore, this option is incorrect.
- **Option B: Intra-uterine insemination**: This technique involves the direct introduction of semen into the uterus. This increases the chances of fertilization and is used particularly in cases of low sperm count. This option is correct.
- **Option C: Intra-cytoplasmic sperm injection**: This method involves injecting a single sperm directly into an egg (ova). This is not the same as introducing semen into the uterus, making this option incorrect.
- **Option D: Gametes intra-fallopian transfer**: This technique involves transferring gametes (eggs) into the fallopian tubes, not the uterus. Thus, this option is also incorrect.

4. **Conclusion**: After analyzing all the options, the correct answer is **B) Intra-uterine insemination**, as it is the technique where donor semen is artificially introduced into the female uterus.
