D. Preventing ovulation

Answer

To solve the question "Which of the following is incorrect regarding copper - T?", we will analyze each option provided in the context of how copper-T functions as a contraceptive device.

### Step-by-Step Solution:

1. **Understanding Copper-T**: Copper-T is an intrauterine device (IUD) that releases copper ions, which have contraceptive effects. It primarily acts to prevent pregnancy.

2. **Analyzing the Options**:
- **Option A: Increasing phagocytosis of sperms**: Copper-T does indeed increase the phagocytosis of sperm. The copper ions create an environment that is toxic to sperm, leading to their destruction by immune cells. This statement is **correct**.

- **Option B: Suppressing motility of sperms**: Copper-T affects the cervical mucus, making it thicker, which can hinder sperm motility. This is a correct function of the device, so this statement is also **correct**.

- **Option C: Preventing implantation of blastocyst**: Copper-T alters the uterine lining (endometrium), making it less suitable for implantation. Therefore, this statement is also **correct**.

- **Option D: Preventing ovulation**: This statement is **incorrect**. Copper-T does not prevent ovulation; it primarily works by affecting sperm and the uterine environment. Ovulation can still occur while using Copper-T.

3. **Conclusion**: The incorrect statement regarding Copper-T is **Option D: Preventing ovulation**.

### Final Answer:
**Option D: Preventing ovulation** is the incorrect statement regarding Copper-T.
