The desire to limit fertility is recognized both by individuals and by nations. The concept of family planning is based on the right of individuals and couples to regulate their fertility and is based in the area of health, human rights and population. Despite the changes in policies and family planning programs worldwide, there are large geographic areas that have not yet met the minimum requirements in this regard, the reasons are multiple, including economic reasons but also ideological or religious. Knowledge on the physiology of the menstrual cycle, specifically ovulation process has been further enhanced due to the advances in reproductive medicine research. The series of events around ovulation are used to detect the "fertile window", this way women will look for the possibility of postponing their pregnancy or actually start looking for it. The aim of this article is to review the current methods of family planning based on fertility awareness, from the historical methods like the core temperature determination and rhythm, to the most popular ones like the Billings ovulation method, the Sympto-thermal method and current methods like the two days, and the standard days method. There are also mentioned methods that require electronic devices or specifically computer designed ones to detect this "window of fertility". The spread and popularity of these methods is low and their knowledge among physicians, including gynecologists, is also quite scarce. The effectiveness of these methods has been difficult to quantify due to the lack of well designed, randomized studies which are affected by small populations of patients using these methods. The publications mention high effectiveness with their proper use, but not with typical use, what indicates the need for increased awareness among medical practitioners and trainers, obtaining a better use and understanding of methods and reducing these discrepancies. |
