This is an eminently readable, conveniently sized book. The text is clearly supported by diagrams, not only of necessary temperature charts, but also those highlighting relevant anatomy and physiology. The text is further punctuated by useful bullet-point lists of the most salient points and clear, simple case histories.

The opening chapter, while concentrating on anatomy and physiology, goes under the title of ‘Fertility awareness‘ and sets the tone of the whole book. It presents the basic science by emphasising that the patient can be easily made aware of the cyclical changes in her body that are consequent upon the reproductive ovarian and menstrual cycles. The underlying philosophy is that by increasing awareness the patient can use herself as a bioassay and avoid therapeutic and investigational medical intervention in the prevention of pregnancy and the management of infertility.

The following nine chapters then deal with basic natural family planning methods and would benefit patients as well as professionals. Thereafter there are three chapters devoted to natural family planning in particular circumstances - postpartum and during lactation, following oral contraception and before the menopause which build on the firm grounding of previous chapters.

Four chapters are devoted to more gynaecological aspects of fertility, including infertility, contraception, termination and sexually transmitted disease. They may prove useful in answering the questions of patients being referred on for consultant opinions.

Overall this excellent book lives up to the claims made on its cover and I will recommend it in the future to all GP trainees working with me.
