### Step 3: Analyze Option C - ICSI (Intracytoplasmic Sperm Injection)

- **Function**: This method is used to treat infertility and is not a method of birth control.
- **Conclusion**: ICSI is not a method of birth control.

### Step 4: Analyze Option D - GIFT (Gamete Intrafallopian Transfer)
- **Definition**: GIFT is a procedure where eggs and sperm are placed directly into the fallopian tubes.
- **Function**: This is also a fertility treatment aimed at helping couples conceive and is not a method of birth control.
