Cu released by Cu Ts plays a role in

Options

A. Increasing phagocytosis of sperms
B. Suppressing sperm motility
C. Suppressing fertilising capacity of sperms
D. Both (2) & (3)

Answer

**Step-by-Step Solution:**

1. **Understanding Copper T (Cu T):**
- Copper T is an intrauterine device (IUD) used for contraception. It is placed inside the uterus to prevent pregnancy.

2. **Role of Copper (Cu) Released by Copper T:**
- When the Copper T is inserted, it releases copper ions (Cu²⁺) into the uterine environment.

3. **Effects of Copper Ions on Sperm:**
- The copper ions released have several effects on sperm:
- **Reduces Motility:** Copper ions decrease the movement of sperm, making it difficult for them to swim towards the egg.
- **Suppresses Fertility:** By affecting sperm function, copper ions reduce the overall fertility of the sperm.
- **Decreases Viability:** The presence of copper ions can also affect the lifespan and fertilizing capacity of the sperm.

4. **Conclusion:**
- The primary roles of Cu released by Copper T are to reduce sperm motility, suppress fertility, and decrease the viability of sperm, thereby preventing fertilization.

5. **Final Answer:**
- The Cu released by Copper T plays a role in increasing phagocytosis of sperms, suppressing sperm motility, and suppressing the fertilizing capacity of the sperms.
