The sponge cannot be used during menstruation. Condom - The male condom , a tubular sheath of synthetic or natural material, is applied to the man's erect penis before penetration of the woman. Because it may remain in place up to 8 hours, the female condom can be inserted prior to lovemaking. Condoms are available without prescription. Local skin irritation may occasionally occur with their use.
Effectiveness increases significantly when either condom is used together with a spermicide.
The diaphragm must be coated with spermicide, inserted into the vagina and placed over the cervix before intercourse. It may be left in place during repeated intercourse, but application of fresh spermicide is recommended and the device must remain in place for 8 hours after intercourse. Oil-based medications or lubricants can damage diaphragm integrity. Women using the diaphragm may experience bladder irritation or infection. Cervical Cap - Smaller than a diaphragm, the cervical cap is also made from a rubbery material and sized to a woman's dimensions by a health professional.
