Sponge placement must be checked to ensure that the cervix is entirely covered. As with all products containing spermicide, the sponge may cause some irritation in either sexual partner. 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.
