Answer:

An IUD is a small T-shaped device that is placed in the uterus by a healthcare provider. It sits inside the uterus, and the cervix keeps it in place. Once it is in, you cannot feel it. There are two types of IUDs: the non-hormonal–copper T IUD and the hormonal–levonorgestrel IUD.

Non-hormonal Copper T IUD

The non-hormonal copper T IUD contains no hormones and is made with copper and plastic. The copper prevents pregnancy by acting as a spermicide (a substance that kills sperm), preventing sperm from reaching and fertilizing an egg.

It starts preventing pregnancy as soon as it is placed. In fact, the copper T IUD is an extremely effective method of emergency contraception when it is placed within five days of unprotected intercourse.

Once in place, it is effective for up to 10 years.

IUDs increase phagocytosis of sperms within uterus and Cu ions supress sperm motility and fertilising capacity.
