Coitus Interuptus
Withdrawal of the penis before ejaculation was historically the only method of contraception. There are no dangerous side effects but reported failure rates of 10/100 women years indicate that it has only limited effectiveness (Table13.1).Furthermore, lack of satisfaction for some partners and anxiety that withdrawal may be too late are additional problems. In one study, 31 % of women discontinued the method because they found it unpleasant but this compared to 54% who found the sheath unpleasant. Although coitus interruptus is not promoted by family planning doctors, there are times when a couple have no other method available; it is certainly more effective than no method at all.
