What Are the Advantages of Artificial Family Planning?

The primary advantage to using methods of artificial family planning is the vastly improved reliability such methods have over most of their "natural" counterparts. The Office of Population Affairs reports that of every 100 women who use oral contraceptives, only five are likely to become pregnant each year. The office goes on to note that the failure rate is even lower among women who take their pills according to directions.

One method of "natural" family planning is the calendar, or "rhythm," method. This involves abstaining from unprotected sex for approximately nine days a month during the time a woman is most likely to conceive. This method fails approximately 24 percent of the time, according to the CDC. The Levonorgestrel intrauterine system IUD has only a 0.2-percent failure rate. Another method of birth control, involving a progestin-secreting implant, works without any effort for up to three years and has a failure rate of just 0.05 percent.

Protection against disease is another advantage of barrier methods of artificial contraception. Barriers such as latex condoms are not only effective at reducing the risk of pregnancy, but they provide effective protection against STDs such as HIV, gonorrhea, chlamydia, human papilloma virus (HPV) and hepatitis B, according to About.com.
