What is the work of copper-T ?

Options

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

Answer

**Step-by-Step Text Solution:**

1. **Definition of Copper-T**: Copper-T is an intrauterine device (IUD) used by women for birth control. It is a small device that is inserted into the uterus.

2. **Mechanism of Action**: The Copper-T has vertical and horizontal arms that contain copper. This copper is gradually released into the uterine cavity.

3. **Effect on Sperm**: The primary function of the copper released by the device is to prevent sperm from traveling through the uterus and into the fallopian tubes. This action reduces the sperm's ability to fertilize an egg.

4. **Prevention of Fertilization**: By inhibiting the sperm's ability to fertilize the egg, Copper-T effectively reduces the chances of pregnancy.

5. **Prevention of Implantation**: Additionally, if fertilization does occur, Copper-T may also prevent the fertilized egg (blastocyst) from successfully implanting in the lining of the uterus.

6. **Clarification of Misconceptions**: It is important to note that Copper-T does not inhibit ovulation or gametogenesis. Its main function is to inhibit fertilization and possibly implantation.

7. **Conclusion**: Therefore, the work of Copper-T is primarily to inhibit the fertilization of the egg, making it an effective contraceptive method.
