Answer

To determine which statement regarding intrauterine devices (IUDs) is incorrect, we can analyze each statement one by one.

### Step-by-Step Solution:

1. **Understanding Intrauterine Devices (IUDs)**:
- IUDs are contraceptive devices inserted into the uterus to prevent pregnancy. They can be of three types: copper-releasing, hormone-releasing, and non-medicated.

2. **Analyzing the First Statement**:
- "They are inserted by the doctors or expert nurses in the uterus through vagina."
- This statement is **correct**. IUDs must be inserted by a trained healthcare professional.

3. **Analyzing the Second Statement**:
- "The device is copper releasing which suppresses the sperm motility."
- This statement is also **correct**. Copper-releasing IUDs release copper ions that inhibit sperm motility.

4. **Analyzing the Third Statement**:
- "It is an ideal contraceptive for females."
- This statement is **correct**. Once inserted, IUDs do not require daily attention and can remain effective for several years.

5. **Analyzing the Fourth Statement**:
- "It decreases the phagocytosis of sperms and makes uterus suitable for implantation."
- This statement is **incorrect**. IUDs actually increase phagocytosis of sperm and make the uterus unsuitable for implantation.

### Conclusion:
The incorrect statement regarding intrauterine devices is the fourth one: "It decreases the phagocytosis of sperms and makes uterus suitable for implantation."
