5.0 out of 5 stars Strict rules, easy explanations and respectfully written, 24 Nov 2010
I have been using FAM for pregnancy avoidance for quite a while now and I was looking for a book worthwhile to recommend to interested friends. I found it. Nofziger explains a strict method of natural birth control that is very effective. The book is written in a manner that is easy to understand even for novices in FAM/NFP. The rules outlined are much stricter than Toni Weshler's TCOYF, and are therefore more safe! Additionally, the book is written in a very respectful manner, which I found very agreeable. It is also very compact which will get you started quickly. I thoroughly recommend this book if you are interested in FAM/NFP.

3.0 out of 5 stars Lax interpretation of FAM rules reduces effectiveness, 24 Nov 2010
I purchased this book after having seen many good reviews on it. I already do use FAM for pregnancy avoidance for many months now. However, I do not recommend this particular book for a novice in FAM! The author's interpretation of the rules, particularly with regards to the less safe pre-ovulation phase, is very lax, which might get you pregnant quicker than you'd like!!! She states the effectiveness of her method with 98% - that is low compared to other studies (European study from 2004, which uses a stricter method and achieves an effectiveness of 99.6%, i.e. as effective as the pill!!!!).
Also, there is some wrong information in this book. The author says that it's ok to measure your basal temperature with a digital thermometer until the beep. Even manufacturers of digital thermometers state in the leaflet that comes with the thermometer that the value at the beep (typically after 30sec) is only a first approximation value. All other literature recommends 3min for a digital thermometer reading and 5min for an analogue thermometer reading. Additionally, she recommends taking your temperature orally, and only if you experience difficulties to take it vaginally. However, all other literature highlights the problems of oral temperature taking as very risky and prone to temperature reading errors. Measure vaginally or rectally if you want to be on the safe side and get clear temperature readings!
If you want to learn FAM with a more effective set of rules I recommend Margaret Nofzinger's book "A cooperative method of natural birth control".
I gave Toni's book 3 stars, because she incorporates a comprehensive and very useful list at the end of the book that explains which medication can influence your cervical fluid or temperature reading, which is unique and invaluable!
