Lea's shield

Lea's Shield (Canada Brand, in US: Lea Contraceptive, in Europe: LEA contraceptivum) is a female barrier method of contraception.

It is a reusable barrier made of medical-grade silicone, inserted in the vagina over the cervix with the intention to block sperm. It is used in conjunction with spermicide.

Lea's Shield most differs from other female barrier methods, such as the cervical cap and diaphragm in that:

it comes in one size (does not need to be specifically fitted to each woman)
it stays in place because of suction
it has a valve (creation of suction, passage of cervical fluids)

Structurally, the shield also has a valve in the middle which allows for the passage of air and cervical fluids. It has a loop to assist in removal.

According to latest studies failure methods are reported at 2.2% (when used with spermicide) to 2.9% (when used without spermicide).

It is FDA approved and available by prescription in the United States, though obtainable over the counter in Germany, Switzerland, Austria, and Canada.
