Question

Why is coitus interruptus not safe method of natural contraception??

Answer 1

Compared to the other common reversible methods of contraception such as IUDs, hormonal contraceptives and male condoms, coitus interruptus is less effective at preventing pregnancy. As a result, it is also less cost-effective than many more effective methods: although the method itself has no direct cost, users have a greater chance of incurring the risks and expenses of either child-birth or abortion. Only models that assume all couples practice perfect use of the method find cost savings associated with the choice of withdrawal as a birth control method. The method is largely ineffective in the prevention of sexually transmitted infections(STIs/STDs), like HIV, since pre-ejaculate may carry viral particles or bacteria which may infect the partner if this fluid comes in contact with mucous membranes.
