Question

List two reasons that make copper releasing IUDs as effective contraceptives.

Hint:

Copper IUDs provide long-term, reversible contraception by creating an inhospitable environment for sperm and preventing implantation. Oral contraceptives work by regulating hormonal levels, inhibiting ovulation, and making the cervix less permeable to sperm.

Answer 1

Two primary mechanisms contribute to the effectiveness of copper-releasing IUDs as contraceptives:
1. Spermicidal action:
- The copper ions released by the IUD generate a hostile environment that impedes sperm movement and their capacity to fertilize an ovum.
2. Implantation inhibition:
- Copper IUDs induce changes in the uterine endometrium, rendering it unsuitable for the implantation and development of a fertilized egg, thereby preventing pregnancy.
