Book excerpt: In the last decade, much of the clinical interest in the field of infertility has focused on advancing reproductive techniques and has often under-appreciated the role that male sexuality plays in reproductive problems. Male sexual function is an integral part of reproduction, and the treatment of sexual dysfunction is an important component for any couple seeking fertility. In some cases, treatment of sexual dysfunction may obviate the need for more invasive cures through advanced reproductive techniques. Thanks to recent clinical and scientific advances in male sexual medicine, the management of men’s sexual dysfunction is often more effective and less invasive than how it was historically described. Men’s Sexual Health and Fertility is the only resource that focuses on the interplay and interconnections between male sexual dysfunction and male factor infertility, gathering insightful data from a panel of experts in male sexual medicine for clinicians who treat couples with fertility issues due to male sexual dysfunction. Chapters discuss advances in the field of men’s sexual medicine, including the latest treatment for erectile dysfunction, the most up-to-date understanding of the physiology and pathophysiology of ejaculation, and the growing body of evidence that low testosterone and male infertility are intimately related. As such, this book provides important information in order to be able to better understand the link between sexual dysfunction and infertility and, most importantly, to better treat male sexual dysfunction in the infertile couple.
