Answer

To determine which of the following options is not included under barrier methods of birth control, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Understand Barrier Methods of Birth Control**:
- Barrier methods are designed to prevent sperm from entering the uterus and reaching the egg. They create a physical barrier between sperm and egg.

2. **Evaluate Each Option**:
- **Option A: Vaginal Pouch**:
- Also known as a female condom, it is designed to prevent sperm from entering the uterus. This is a barrier method.
- **Option B: Diaphragm**:
- A diaphragm is a dome-shaped device that covers the cervix and is used with spermicide. It is also a barrier method.
- **Option C: Cervical Cap**:
- Similar to the diaphragm but smaller, it fits snugly over the cervix and is used with spermicide. This is another barrier method.
- **Option D: Implant**:
- An implant is a hormonal method of birth control that involves inserting a small rod under the skin to release hormones that prevent ovulation. This does not create a barrier to sperm.

3. **Identify the Correct Answer**:
- Since the vaginal pouch, diaphragm, and cervical cap are all barrier methods, while the implant is not, the correct answer to the question is **Option D: Implant**.

### Final Answer:
**D: Implant**
