The trend of natural contraception is on the rise in France, with 7.5% of women using these methods in 2023, up from 4.6% in 2016. This shift is partly driven by social media influencers who advocate for natural birth control as a means of empowerment and liberation from hormonal contraceptive side effects. However, experts caution that natural methods, which include techniques like the calendar method and temperature tracking, require strict adherence and can be significantly less effective than traditional hormonal methods. A review by INSERM, the French National Institute of Health and Medical Research, found that less than 20% of fertility apps accurately predict fertility cycles, and many share user data without consent. Gynaecologists warn that these methods may not be suitable for women with irregular cycles, as various factors can skew measurements. Despite the appeal of natural methods, experts recommend consulting with healthcare professionals before making a switch.
