Finding the best types of birth control can be challenging for couples and other sexually active men and women. As attempts to avoid pregnancy have been common since the dawn of mankind, numerous techniques and devices have been developed over the centuries to assist with family planning.The highest failure rate of it is the natural method. This is where no artificial means are used to try to prevent a pregnancy, but the couple tries to follow the rhythms of the woman's own body. They try to have sex only in a time frame where the woman is unlikely to be ovulating. Unfortunately, because no woman's cycle is identical every month, no calculation can be entirely accurate. This natural birth control method has a twenty-five percent failure rate and one out of every four women using this method will become pregnant.

Cervical barriers are devices that are contained completely within the vagina. The contraceptive sponge has a depression to hold it in place over the cervix. The cervical cap is the smallest cervical barrier. Depending on the type of cap, it stays in place by suction to the cervix or to the vaginal walls. The diaphragm fits into place behind the woman's pubic bone and has a firm but flexible ring, which helps it press against the vaginal walls.The object that is most commonly used by the male is called the condom, which is a piece of latex that covers the penis, and prevents the travel of sperm into the vagina. The female object that is used is called the diaphragm, which is the same thing as a male barrier, its just used on the female, and is connected to the cervical bone so it is secure.

The Depo-Provera shot [medroxyprogesterone acetate] is popular because it lasts for 3 months, it does not contain estrogen and is highly effective in preventing pregnancy. The injection is given into the woman's buttocks or the arm muscle. But really, think about it for a minute. Our physical makeup is dramatically different from that of our male counterparts. We have to train nearly twice as hard to make any substantial gains in the gym, and we're genetically preprogrammed to store more fat than men, all because of the differences in our hormonal makeup.
