Best answer

Answer: 4. They suppress sperm motility and fertilising capacity of sperms.

Key idea: Cu ions released by the IUD act mainly on sperm.

Copper ions suppress sperm motility and the fertilising capacity of sperm. (Hormone-releasing IUDs make the uterus unsuitable for implantation and the cervix hostile to sperm.) Copper does not stop gamete formation or ovulation. Answer: (4).
