The function of copper ions in copper releasing IUD's is:

  1. A
    They suppress sperm motility and fertilising capacity of sperms
  2. B
    They inhibit gametogenesis
  3. C
    They make uterus unsuitable for implantation
  4. D
    They inhibit ovulation

Solution & Step-by-step Explanation

Copper-releasing IUDs (like CuT) release copper ions into the uterine environment. These ions are toxic to sperms; they suppress sperm motility and reduce their fertilizing capacity, thereby preventing pregnancy.
