Several years ago, a colleague began developing a historical timeline of fertility awareness research findings, technologies, and publications. What started as a personal project grew and she solicited feedback from several FABM professionals, myself included. I understood the importance of such a timeline and its contribution to furthering awareness about the benefits of fertility awareness among both health professionals and consumers alike. While the original document<\/a> is available and accessible online, I felt that there were still gaps in the history being told.<\/p>\n

What follows is a timeline that has been expanded from the original, with additional research, as well as information and events relevant to Hebrew speakers in Israel (Any item marked with an asterisk [*] in the Line # column refers to milestones that have either been added or modified from the original).<\/p>\n

I felt inspired to expand on the original outline for a number of reasons. First and foremost, most people, including medical professionals, are not aware of the historic and scientific development of FAM and other Sympto-Thermal Methods. It will surprise many to learn that FAM\/STM variations are not something new and that they are based on research that has evolved during the past 160 years! The timeline provides a valuable context for understanding the progression and accumulation of knowledge about the human body, hormones, the menstrual cycle, and fertility potential over a wide stretch of time. The scientific journey is far from over, as researchers, for example, continue to discover new hormones and their connections to a vast array of functions in the human body.<\/p>\n

The bottom line is this: We have an extensive body of knowledge that both clarifies and confirms the science behind FAM and other STMs while conferring its credibility as a legitimate tool for those interested in natural, evidence-based approaches to fertility planning.<\/p>\n

68<\/td>\n2019<\/td>\nA prospective study of the family planning app Dot<\/a> for pregnancy prevention finds that the app is as effective as other modern methods of contraception. \u201cTheir study, published in the European Journal of Contraception and Reproductive Healthcare, is the first to test a fertility app using best-practice guidelines for assessing the effectiveness of family planning methods.

67<\/td>\n2018<\/td>\n\u201cEffectiveness of Fertility Awareness-Based Methods for Pregnancy Prevention: A Systematic Review<\/a>\u201d is published. Their conclusion is that \u201c[s]tudies on the effectiveness of each fertility awareness-based method are few and of low to moderate quality. Pregnancy rates or probabilities varied widely across different fertility awareness-based methods (and in some cases, within method types), even after excluding low-quality studies. Variability across populations studied precludes comparisons across methods.\u201d<\/td>\n<\/tr>\n

58<\/td>\n2010<\/td>\nDr. Marguerite Duane connects with Dr. Bob Motley to start the Fertility Appreciation Collaborative to Teach the Science (FACTS), an initiative dedicated to teaching healthcare professionals about FABMs and the science behind them.\n

[It is important to note that, while FACTS presents itself as evidence-based and uses secular language in its materials, FACTS is ideologically aligned with natural family planning \u2013 specifically, the Creighton Model. Dr. Duane, herself, is a certified Creighton Model practitioner and is an associate scholar<\/a> with the Charlotte Lozier Institute and a speaker<\/a> for the Catholic Information Center. The reason why FACTS is included in this document is because it is the only organization that advocates for FAM education and training for medical students and -professionals in the United States.]<\/p><\/td>\n<\/tr>\n

35*<\/td>\n1982<\/td>\nAn analysis of the use-effectiveness of fertility awareness methods<\/a> of family planning among clients in a San Diego, California, clinic reveals a 12-month failure rate (life-table method) of 13\u00b72 failures per 100 women. This is comparable to results from previous studies of the use of fertility awareness methods (as defined by the sympto-thermal method) in developed nations. Also consistent with previous studies is the finding that fertility awareness method users tend to be young and well-educated. Motivational factors are identified as being most closely associated with successful use of this method of family planning.\n

15<\/td>\n1941<\/td>\nW. W. Greulich becomes<\/a> one of the first to provide usable data on the time of ovulation in relation to the basal body temperature through performing and observing operations on the ovary and reporting the microscopic observation of excised corpora lutea.<\/td>\n<\/tr>\n
14*<\/td>\n1932<\/td>\nThe Rhythm of Sterility and Fertility in Women<\/a>, by Dr. Leo Latz, is published.\n

This book describes for the first time the Catholic Safe Days method as a method of family planning. The use of the term \u201csafe days\u201d is first described and Ogino\u2019s theory that ovulation always occurs about two weeks before menstruation is verified by Dr. Latz. During this time, the church opposed the idea that a woman should have control over her body to prevent pregnancy, believing that \u201cit is impossible to play with a higher power.\u201d<\/p><\/td>\n<\/tr>\n

8<\/td>\n1905<\/td>\n\u201cTheodoor, Hendrik Van de Velde<\/a>, a Dutch gynecologist, publishes a series of biphasic charts and notes that the length of elevated temperatures prior to menstruation is independent of the length of the menstrual cycle, thus demonstrating that the luteal phase is constant. He also makes the connection that the upward thermal shift is related to ovulation.\u201d<\/td>\n<\/tr>\n
7<\/td>\n1897<\/td>\nIt is discovered that \u201covarian extract\u201d can be administered to postmenopausal individuals to alleviate hot flashes. This is considered the first reported use of hormonal therapy.<\/td>\n<\/tr>\n
6<\/td>\n1877<\/td>\n\u201cThe Question of Rest for Women during Menstruation<\/a>,\u201d is published by Dr. Mary Putnam Jacobi.

3<\/td>\n1855<\/td>\n\u2018Dr. W. Tyler Smith, a member of the Royal College of Physicians in London, describes cervical mucus: \u201cThe use of the cervical mucus is probably twofold. In the first place, it closes the cervix uteri and defends the cavity of the fundus from external agencies as completely as though it were a shut sac.\u201d That would be during the infertile times. Dr. Smith then continues to describe this mucus during the fertile phase of the cycle. \u201cIn the second place, it appears to afford a suitable medium for the passage of the spermatozoa through the cervix uteri into the uterine cavity.\u2019 (Jan Mucharski, History of the Biologic Control of Human Fertility<\/a> with a Foreword by Edward F.
