This new edition provides an update on the molecular mechanisms that regulate spermatogenesis. In addition to the rodent as a study model, chapters also include research on studies in humans. It includes the latest approaches of studying spermatogenesis, such as the use of bioinformatics, molecular modeling and others which are not commonly found in published materials. It also reviews the latest developments in the field, such as studies on the role of regulatory RNAs on spermatogenesis. Due to the declining fertility rate among men, a brand new chapter highlights the impact of environmental toxicants on spermatogenesis.

This book was written by many outstanding investigators who have spent decades to study different aspects of blood-tissue barrier function. They have summarized some of the latest and fascinating development in their fields of research including the blood-brain barrier, the blood-retinal barrier, the gut barrier, the blood-biliary barrier, the blood-follicle barrier, the blood-epididymis barrier, the blood-testis barrier, the tight junction barrier in general as well as barriers in the female reproductive tract. Included are also chapters that focus on topics that are physiologically applicable to all blood-tissue barriers. Many of these chapters also include information on specific human diseases, such as pathological changes of the gut barrier that cause bowel disorders resulting from inflammation of the epithelial lining in the intestine, and infertility in men as a result of disruption of the blood-epididymal and/or blood-testis barriers; and on new therapeutic approaches (e.g., drug delivery across the blood-brain and the blood-retinal barriers).

Senior investigators internationally have here collaborated to produce an international reference work. Each contributor provides critical and thought provoking concepts and ideas based on the latest developments in their field. The result is a must read and timely reference work for investigators who are interested in how spermatogenesis is currently understood and which are the most promising avenues for future research; an Introduction sets the context for the chapter and points out the relevance of the research for basic research scientists and clinicians.
