Can we choose the sex of our children? Why are more boys born than girls? Does the quality of intercourse affect the chance of having a baby? Human reproduction is cumbersome, prolonged, and rather messy. It is no easy task to unravel the intricate patterns of the cyclic, seasonal and social variations on our sexual activity and our ability to reproduce. This unique account of these patterns, with its clear but entertaining style, will appeal to all from the layman, whose enthusiasm is mainly practical, to the medical student and the General Practiioner, for whom the subject is of professional interest. Sir Alan Parker has had a long and distinguished career, which included election to the Royal Society at the age of 33. He is now an Honorary Fellow of University College London and Christ's College, Cambridge, Chairman of the Galton Foundation, and Chief Scientist for the world's only turtle farm.
