The function of copper ions in copper releasing IUDs is :

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

Answer

(1) They suppress sperm motility and fertilising capacity of sperms.

Solution

As per NCERT, IUDs increase phagocytosis of sperms within the uterus, and the Cu ions released suppress sperm motility and the fertilising capacity of sperms.

⇒ Hormone-releasing IUDs (e.g. LNG-20), not copper ones, make the uterus unsuitable for implantation and the cervix hostile to sperms.

∴ Copper ions suppress sperm motility and fertilising capacity.
