Barrier contraceptives - Female condoms

E. Female condoms:

The female condom is a thin, soft, loose fitting polyurethane plastic pouch that lines the vagina.
It has two flexible rings, one inner ring at the closed end used to insert the device inside the vagina and to hold it in place and outer ring which remains outside the vagina and covers the external genitalia. Because the device is made from polyurethane, the female condom can be used with any type of lubricant without compromising the integrity of the device.
Women tended to accept the device more favorably than did men.
But overall difficulties of insertion decreased as experience with device increased , and use became more comfortable and acceptable in practice.

Advantages:
Female controlled, more comfortable to women, less decrease in sensation than with the male latex condom.
Female condom offers greater protection as it  covers both internal and external genitalia. More convenient than male latex condom that it can be inserted pre-coitus.
Stronger than the male latex condom, as polyurethane is 40% stronger than latex.

Disadvantages:
Female condom is not aesthetically pleasing.
The coverage of external genitalia had a decidedly negative impact on the device's aesthetics and acceptance.
Some people dislike of the appearance of the device, noise associated with use and size of the device.
Partner resistance may be seen in some cases.
Difficulties in insertion and removal can occur.
There are few cases of slipping of the penis between the device and woman's body or slippage and breakage of device itself.
It is relatively expensive than other methods.

Effectiveness:
Typical failure rate is 21% as commonly used.
But only 5% when used correctly and consistently.
