Safe sex using condoms and spermicides
It is important to practice safe sex, both to avoid unwanted pregnancies and to reduce the risk of contracting a sexually transmissible infection such as genital herpes, hepatitis, gonorrhoea or HIV.
A woman taking an oral contraceptive pill will not be protected against sexually transmissible infection, only pregnancy.
The chance of becoming pregnant while using a condom is 2 to 10 per cent, depending on how carefully it is used and whether it is used in conjunction with a spermicide.
If you have unprotected sex or if the condom may have failed, see a doctor as soon as possible. Emergency contraception (the ‘morning after pill’) is available on prescription, but must be used within 72 hours of unprotected sexual intercourse.
Condoms
Condoms provide a physical barrier to sperm and sexually transmitted diseases, and their effectiveness is dependent upon their correct use. Condoms should always be stored away from heat and sunlight, and should be discarded if they are beyond their expiry date.Condoms may be damaged by heat, if they are handled roughly, or if the vagina is too dry. Spermicides provide only limited lubrication, so you may also need a lubricant. Suitable lubricants include Ansell Personal Lubricant and KY Jelly.
Vaginal antifungal creams can damage condoms and diaphragms. Unsuitable lubricants (such as baby or cooking oils) may also damage condoms. Vaseline or butter can destroy the condom barrier within 60 seconds.
Spermicides such as Ortho-Gynol and Ortho-Creme should be used in conjunction with condoms and diaphragms to increase their reliability. Condoms without spermicide include Durex, Lifestyles and Saturn. Condoms with spermicide include Durex Extra Safe, and Lifestyles Spermicidal.
