This volume surveys the state of knowledge and research on the determinants of human reproduction. It adopts an inter-disciplinary approach and integrates information from demographic, epidemiological and biological studies of fertility. The chapters provide a comprehensive overview of reproductive processes, including puberty and menopause, conception and fetal loss, and the effects of sexually transmitted diseases and lactation. The volume also considers the effects on fertility of nutrition and stress, environmental and occupational hazards, and social behaviour, and includes clinical papers on fertility following contraceptive use and treatment of infertility. Findings from original research on the determinants of human reproduction are also presented.
