It is very important to choose the correct birth control method when you want to avoid unwanted pregnancies. Birth control or contraception refers to mechanisms which are intended to reduce the likelihood of the fertilization of an ovum by spermatozoa. The choice of birth control depends on factors such as a person's health, number of sexual partners, frequency of sexual activity and the desire to have children in the future. Failure rates are another key factor to be considered before employing any method. The most effective way to avoid both pregnancy and sexually transmitted infections is to practice total abstinence. Some examples of different contraceptives are barrier methods, hormonal methods, sterilization, behavioral methods, coitus interruptus, ormeloxifene and so on.

When choosing to avoid unintended pregnancy with certain sexual behavior, the methods are called behavioral methods of birth control. Women and men have used behavioral methods of birth control to decide when and whether to have a child since the beginning of the concept of birth control. Behavioral methods of birth control, especially the coitus interruptus, are widely used by couples who have very limited alternatives either due to inconvenience, special challenges or ethnic and cultural reasons. These methods, used for thousands of years by our ancestors, still play important roles in family planning today.
Coitus interruptus is the act of removing the penis from the vagina just prior to ejaculation, effectively not allowing the semen to enter the vagina. This method has been present since time immemorial and used by millions of people the world over. The success of this method of contraceptive depends on its correct and consistent usage. Actual failure rate can be as high as 15 to 25 percent. This is because of various reasons. The penis may not have been fully withdrawn before ejaculation or the semen may have been spilled too near the vagina and leaked in by physical contact after ejaculation. Sometimes traces of semen remains inside the penis after ejaculation and vaginal penetration soon after may allow the semen to enter the vagina. For this reason, it is recommended that the male partner of the users of coitus interruptus should urinate between ejaculations, so that the semen in the urethra is washed away. Any objects that might come near the woman's vulva should also be washed before intercourse to reduce risk of semen left from previous ejaculations like the hands and the penis.
It is widely believed that the pre-ejaculation or ‘cowper’s fluid’ discharged by the penis prior to ejaculation contains sperms cells. If so then this could easily lead to pregnancy even if the coitus interruptus method is used. However after many small studies and individual research on the subject, there is as yet no objective evidence that there are any viable sperms in the fluid. The more likely reason of failure seems to be due to sperms left from previous ejaculation. Some of the advantages of coitus interruptus are no monetary cost incurred, requires no artificial devices, has no physical side effects, and can be practiced without a prescription or medical consultation.
