The sections on nutrition, contraception, screening tests, environmental hazards, food borne infections, and alcohol and caffeine consumption have been thoroughly revised and the text as a whole has been revisited to ensure it conforms with the latest guidelines. The design is being up-dated as well, to make it more appealing to contemporary couples. What hasn't changed, however, is the comprehensiveness of the material, which helps readers to maximise their chances of becoming pregnant using natural means, wherever possible, and the wide range of illustrative material.
