Question

Which of the following ions plays an effective role in the activity of IUDs?
A. Iron
B. Zinc
C. Copper
D. Ammonium

Answer 1

Hint: The copper IUD is a method of long-acting, reversible birth control. The male reproductive cell is destroyed by copper ions in copper-releasing IUDs. Copper ions interact with the cervical mucus near the uterus' opening to have a spermicidal action.

Complete Step by Step Answer:
An intrauterine device (IUD) with copper, also known as an intrauterine coil, is one form of intrauterine device that contains copper.
The extra contraceptive effects of copper IUDs are caused by the presence of copper ions. Because copper ions cause an inflammatory response in the uterus, sperm cannot reach the egg to fertilise it and create an embryo.
Within the female reproductive system, the IUD releases copper ions that prevent sperm from moving. Fertilization is prevented by suppressing the sperm's motility.
The motility of sperm is impeded by cuprous ions. Consequently, IUDs that release copper serve as efficient contraceptive devices.
Even if fertilisation takes place, the uterus's high copper content will stop fertilised eggs from implanting. Thus, copper T-devices outperform other forms of birth control in terms of efficacy. Untimely bleeding, a copper allergy, automatic ejection, and uterine infections are a few adverse effects of copper intrauterine devices.
Hence, the correct option is C. Copper.

Note: Five days after unprotected sexual contact, Copper T is used as an emergency contraceptive. When the intrauterine device is removed, the copper ions' function comes to an end. The uterus returns to normal as a result. Once eliminated, copper T won't influence fertility or cause problems with future childbearing plans. The body's hormonal system is not affected by this gadget. It is also reasonably priced.
