Question

Which contraceptive device makes the uterus unsuitable for implantation?

• A. Multiload $375$
• B. $CuT$
• C. Lippes loop
• D. Progestasert

Answer 1

The correct option is D

Progestasert

Hormone releasing IUDs :
Hormone releasing IUDs are a type of intra uterine devices which make the cervix hostile by making the mucus thick and sticky, which prevents the sperms from reaching the uterus.
They also change the environment of the uterus making it unsuitable for the implantation of the embryo.
Examples: LNG-20 and progestasert.

Progestasert :
Progestasert is a hormone-releasing IUD. It turns the cervix hostile for sperms and brings changes in the uterus making it unsuitable for the implantation.

CuT :
CuT is a “T”-shaped device made up of plastic and copper wires. It is safe to use and prevents the progress of the sperm from fertilizing the ovum. It is a copper-releasing IUD.

Lippes loop :
Lippes loop are plastic or metal (S-shaped) objects placed in the uterus of the female to prevent implantation. It is a non-medicated IUD.

Multiload :
Multiload $375$ is a copper releasing IUD which prevents fertilisation as the copper ions released reduce the motility and fertilising ability of sperms.

Final answer :
a.) Progestasert
