Answer

To answer the question "Which contraceptive device makes the uterus unsuitable for implantation?", we can follow these steps:

### Step 1: Understand the Types of Contraceptive Devices
- There are various types of contraceptive devices, particularly intrauterine devices (IUDs). These can be classified into three main categories: non-medicated IUDs, copper-releasing IUDs, and hormone-releasing IUDs.

### Step 2: Identify the Types of IUDs
- **Non-medicated IUDs**: These do not contain any medication. An example is the Lippie's Loop.
- **Copper-releasing IUDs**: These release copper ions, which help in preventing sperm motility. Examples include Copper-T and Multi-load.
- **Hormone-releasing IUDs**: These release hormones such as progesterone. They work by making the uterus unsuitable for implantation.

### Step 3: Focus on the Function of Hormonal IUDs
- Hormonal IUDs, such as those releasing progesterone, not only prevent sperm motility but also alter the uterine lining. This alteration makes the uterus an unfavorable environment for implantation of a fertilized egg.

### Step 4: Analyze the Given Options
- The options provided are:
1. Progesterone
2. Copper T
3. Lippie's Loop
4. Multi-load

### Step 5: Determine the Correct Answer
- Among the options, **Progesterone** is the hormone-releasing IUD that makes the uterus unsuitable for implantation. Therefore, the correct answer is **Progesterone**.

### Final Answer:
The contraceptive device that makes the uterus unsuitable for implantation is **Progesterone**.
