25 Natural family planning What are they? Withdrawal method - penis is withdrawn from the vagina prior to ejaculation Natural method – sex is avoided at fertile times of the month. Fertility is monitored using the following methods –Keep a daily record of your body temperature using a special fertility thermometer –Look for changes in the stickiness of the mucus around the entrance to the womb –Calculate when ovulation is most likely to take place by counting the number of days from your last period (this only works if your periods are regular) –Look for other signs such as mood changes and breast tenderness which tend to happen in the second half of your menstrual cycle (measured from the start of one period to the beginning of the next)

The withdrawal method is highly unreliable because small drops of sperm can escape from the penis into the vagina before the man ejaculates Fertile periods not confirmed until three to six cycles are completed Necessary to keep daily records Events such as illness, stress and travel may make fertility indicators harder to interpret Necessitates intercourse avoidance during the fertile time Both partners need to be very committed to the method Does not protect against STIs

27 Emergency contraception What is it? Emergency method that can be used after unprotected sex or when another contraception method has failed (e.g. split of condom) Only intended as a back-up, not to be used regularly How does it work? Emergency methods work mainly by preventing ovulation and fertilisation They also have local effects on the uterus They are not effective once the process of fertilisation and implantation has begun

28 Emergency contraception What options are there? Emergency (or morning after) pills - can be taken up to 72 hours or three days after intercourse.

29 Sterilisation What is it? Permanent method of contraception for people who do not want children now or in the future How does it work? Male sterilisation The tubes that carry sperm are cut, so that while a man can still ejaculate, no sperm is present Female sterilisation The fallopian tubes are cut or blocked so that the egg cannot travel down to meet sperm

30 Sterilisation What are its main advantages? Almost 100% effective Does not interrupt sex Can be performed and forgotten What are its main disadvantages? Cannot be reversed (except by using complex and dangerous surgery which is not successful in all cases) Do not protect against STIs
