Andrology is the fastest growing subspecialty in urology and has recently achieved remarkable advances in the understanding of the erectile mechanism and in reproductive medicine. Male Infertility and Sexual Dysfunction presents all the current avenues of treatment with emphasis on multidisciplinary considerations. Chapters are written by select international authorities presenting indepth coverage of their areas of expertise. Each topic will cover the background, anatomy, physiology, diagnosis, classification, and treatment (medical and/or surgical). Part I focuses on the study of male infertility and includes discussions of the basic sciences, office evaluation, laboratory and imaging techniques, and the use of testicular biopsy. This is followed by specialized chapters dealing with immunologic infertility, genital inflammation, reactive oxygen species, medical management, sperm processing and preventive adolescent andrology. Part II reflects a more diverse format in the coverage of sexual dysfunction and includes discussions of androgen insufficiency, nocturnal penile tumescence studies, neurotransmission, penile neurology, premature ejaculation, psychogenic impotence and the latest medical, noninvasive and surgical treatments.
