Birth Control Options

Cervical Cap

What is it?

The cervical cap is a reusable barrier method of birth control that fits inside the vagina. It is a thimble-shaped silicone cap that fits snugly over the cervix, preventing sperm from getting inside.

• The cervical cap should always be used with a spermicide
• Women must have the cervical cap properly fitted by a health professional. This ensures the correct size so it will stay in place.

How does it work?

When positioned properly, the cervical cap places a physical barrier between the sperm and the cervix so that the sperm cannot reach the egg. The spermicide works to destroy sperm on contact.

• The cervical cap must be left in the vagina for 6- 8 hours after sex
• After use, the cervical cap can be washed with mild soap and water, air dried and stored in its case away from excessive heat and light
• Before each use it should be inspected for any small holes or tears
• If properly cared for, most cervical caps will last for 1 to 2 years

How effective is it?

There is a difference in effectiveness when used by women who have already given birth and women who have not:

• For women who have not given birth, the cervical cap is 91% effective with perfect use. With typical use, it is about 80% effective in preventing pregnancy.
• For women who have previously given birth, the cervical cap is significantly less effective: 74% effective with perfect use, and 60% effective with typical use.
  

What are the advantages?

• Reusable
• Does not contain hormones
• Provides some protection against certain sexually transmitted infections (STIs)
• Can be used in combination with a male condom to increase birth control effectiveness and to protect against STIs
• Offers women privacy and control because it can be inserted up to 6 hours before sex

What are the disadvantages?

• Requires proper insertion technique
• Cannot be used by people who are allergic to spermicides
• Does not protect against certain sexually transmitted infections
• Should not be used during menstruation (period)
• May cause vaginal odour and discharge
• In rare cases, the cervical cap may cause toxic shock syndrome if it is not removed within 48 hours
• May become dislodged during intercourse (See Emergency Contraception)
• Must be fitted and prescribed by a health professional
