Cervical Barriers are forms of birth control that are used in conjunction with spermicidal foams or jelly that together prevent sperm from passing the cervix. It’s important to note before using these that they are not 100% effective in preventing pregnancy. The best form of birth control is always abstinence.
Diaphragms and cervical caps are types of cervical barriers that are fitted to the individual using them. Their doctors will take the necessary measurements to fit these barriers. FemCap and Lea’s Shield are cervical barriers that are not fitted to the individual. All types of cervical barriers are inserted the same way and are recommended for use with spermicidal foam or jelly.
The foam or jelly is used to coat the dome and rim of the cervical barrier. The barrier is then inserted into the vagina with the coated side facing upwards. This can be done by the woman in privacy or done with her partner’s assistance. It’s important that this not be an embarrassing situation for the female. If anything, this should be an experience of intimacy between partners.
The placement of the barrier with the spermicidal coating is intended to block the sperm at the cervix. Should the sperm go beyond the barrier, the lubricant should kill it before it can induce pregnancy. Again, keep in mind that no form of contraception is 100% protection and the best form of protection is still abstinence. Sex should be practiced by those who are prepared to deal with the possibility of pregnancy.
