Question

Assertion : CuT, Cu7 and multiload 375 are the hormones releasing IUDs.
Reason: Cu ions released by some UDs affect the ability of the uterine wall to support embryos that cause contraception.
A) Both assertion and reason are correct and reason is the correct explanation for assertion
B) Both assertion And reason are correct but reason is not the correct explanation for assertion
C) Assertion is correct but reason is incorrect
D) Both Assertion and reason are incorrect

Answer 1

Contraceptives are the devices and other medications used to prevent unplanned birth. It is an effective tool in offering pregnancies which are unwanted by an individual by inhibiting different steps in Fertilisation and to avoid the formation of a fetus.

Complete answer:
Cu7 and Cu T are the contraceptive tools which are inserted into the uterus in the presence of a gynaecologist. The nomenclature is based on its characters, as it can release copper ions and it’s in a shape of T and seven hence the name Cu7 or Cu T. So assertion is correct. This is used by women of all ages as it can be effective for an average of pro 12 years. It focuses to prevent Fertilisation as their primary goal. The metal ions released from CuT acts as a toxin to sperm this is why it is also known as spermicide as they increase not only copper ions but also prostaglandins as white blood cells within the uterus. This can be used as emergency contraceptives where copper T can disrupt the implantation as its embryo to the uterine wall thus its known as contraceptives and yes the reason is also true. There is not proper evidence as it is used as abortifacients as they do not induce embryonic loss. Hence, Option B is correct, as the reason is not correct for the assertion since contraceptive effects are not due to release of copper ions.

Hence, the correct answer is Option ‘B’.

Note: This is not a permanent contraceptive method as the removal of this instrument from the uterus can induce fertility again.There are different methods of contraception, including: long-acting reversible contraception, such as the implant or intrauterine device (IUD) hormonal contraception, such the pill or the Depo Provera injection.
