Select the correct option:
Solution
Inducing local inflammatory reaction toxic to sperm
- Intrauterine Devices (IUDs): Effective contraceptive methods inserted into the uterus.
- Copper-releasing IUDs (e.g., CuT, Cu7, Multiload 375).
- Mechanism of Action: The copper ions (Cu2+) released into the uterine fluid:
- Increase the phagocytosis of sperm within the uterus.
- Suppress sperm motility and the fertilizing capacity of the sperm.
- Induce a sterile inflammatory reaction in the endometrium that is toxic to both sperm and the blastocyst.
- Non-hormonal: Unlike oral pills, copper IUDs do not prevent ovulation or suppress pituitary hormones.
