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 reasons that make copper releasing IUDs effective contraceptives:
1. Toxic to sperm:
- The copper released by the IUD creates a toxic environment for sperm, impairing their motility and ability to fertilize the egg.
2. Prevention of implantation:
- Copper IUDs alter the lining of the uterus, making it inhospitable for a fertilized egg to implant and grow, thus preventing pregnancy.
