This definitive and essential source of reference has been thoroughly up-dated and revised to meet the requirements of all laboratories involved in the analysis of human semen. The book sets out the fundamental laboratory techniques that should be employed in the diagnosis of male infertility. The text includes descriptions of how to construct a conventional semen profile and provides standardized protocols for performing several optional diagnostic procedures. Such techniques are essential in the evaluation of infertile couples and in assessing fertility in men whose sperm production is suppressed by potential anti-fertility compounds or by toxic agents: they are also of interest in forensic medicine and in connection with artificial insemination. Previous editions of this volume have established themselves as the gold standard in the area of fertility investigation and treatment: this new edition continues that tradition and will be the benchmark for setting more rigorous standards for future years.
