Barrier methods, chemical and natural contraception

The desire for a safe prevention concerns people for several thousand years.Many effective, but also nonsensical methods have been discovered or invented. Some of these contraceptives have been developed and are still used today in modern forms as an alternative to hormonal contraception. Already since the 19th Century, there are industrially produced vaginal diaphragmas and condoms, which revolutionized contraception at the time. Besides condoms and vaginal diaphragmas still include the female condom and cervical cap to the barrier methods.The aim of these methods is to prevent the ascension of sperm into the uterus. Chemical means of prevention can increase the safety of other methods, especially barrier methods yet.

The close monitoring of the female cycle, with all its changes, such as the change in the basal temperature, can be used to determine the fertile days. For the calculation of the ovulation day now exist some modern devices.

Not a few women in the gynecological don't like to use hormonal contraceptives any longer and want a safe contraception without hormones. It is important that they are aware of the precise application of the methodology and know their body well to keep the Pearl Index as low as possible.
