What is the work of copper-T ?

Options

A. To inhibit ovulation
B. To inhibit fertilization
C. To inhibit implantation of blastocyst
D. To inhibit gametogenesis

Answer

**Step-by-Step Solution:**

1. **Definition of Copper-T**: Copper-T is a type of contraceptive device known as an Intrauterine Device (IUD). It is specifically designed for use in females to prevent pregnancy.

2. **Insertion**: The Copper-T is inserted into the uterine cavity by a healthcare professional. This placement is crucial for its function as a contraceptive.

3. **Composition**: The Copper-T is covered with a copper thread. This copper component is essential for its contraceptive action.

4. **Mechanism of Action**: The copper ions released from the Copper-T have specific effects on sperm:
- They affect sperm motility, which refers to the movement and speed of sperm.
- They can damage the sperm, making them less viable.

5. **Effect on Fertilization**: By damaging the sperm and affecting their motility, the Copper-T acts as a spermicide. This means that it prevents fertilization from occurring. If the sperm cannot reach and fertilize the egg, pregnancy cannot happen.

6. **Conclusion**: The primary work of Copper-T is to inhibit fertilization by affecting sperm function, rather than preventing ovulation or implantation.
