If a woman is using a copper-T, will it help in protecting her from sexually transmitted diseases? - Science

Short Note

 If a woman is using a copper-T, will it help in protecting her from sexually transmitted diseases?


Solution 1

No, because copper-T will not prevent contact body fluids. Thus it will not protect her from sexually transmitted diseases.

Solution 2

No. Using a copper-T will not provide a protection from sexually transmitted diseases, as it does not prevent the entry of semen. It only prevents the implantation of the embryo in the uterus.
