Answer:
The correct answer is diaphragm.
Explanation:
One of the barrier methods of controlling birth is the diaphragm. It is abstemiously efficient, with a one-year failure rate of approximately 12 percent with the typical application. It is positioned over the cervix with spermicide prior to having sex and is left in position for about 6 hours post-sex.
It is a rubber barrier that holds the spermicide against the cervix. The spring in the diaphragm's rim produces a seal against the walls of the vagina. The diaphragm covers the cervix and physically inhibits sperm from getting inside the uterus via the internal orifice of the uterus. Basically, the diaphragm has an application with spermicide, and it is broadly considered that the spermicide substantially enhances the efficacy of the diaphragm.
