Sexual Medicine represents a dynamic and varied field, covering a wide range of clinical specialties. This special Focus issue of Nature Reviews Urology contains specially commissioned articles that present the most exciting research in the sexual medicine spectrum. Reviews cover the topics of regenerative medicine, the neurobiology of the sexual response, the hormonal control of ejaculation and management strategies for micropenis. We also include a Perspectives discussing the challenges facing the field and a number of News & Views articles discussing recent research in sexual medicine.

REVIEWS
Sex for fun: a synthesis of human and animal neurobiology
Janniko R. Georgiadis, Morten L. Kringelbach & James G. Pfaus
doi:10.1038/nrurol.2012.151
Nature Reviews Urology 9, 486-498 (2012)
Georgiadis et al. provide a comprehensive description of the available animal and human literature on sexual reward and sexual incentive motivation, highlighting the major points of convergence and divergence across species. They discuss a neural concept of human sexual behavioural control and suggest novel testable hypotheses for future sex research.
The hormonal control of ejaculation
Giovanni Corona, Emmanuele A. Jannini, Linda Vignozzi, Giulia Rastrelli & Mario Maggi
doi:10.1038/nrurol.2012.147
Nature Reviews Urology 9, 508-519 (2012)
Owing to the expansive nervous components participating in the ejaculation reflex, that multiple neurotransmitters are involved is unsurprising. In this Review, the authors focus on the endocrine control of the ejaculatory reflex and suggest that widely available endocrine therapies might be effective in treating sexual disorders such as premature ejaculation.
Therapeutic strategies for patients with micropenis or penile dysmorphic disorder
Oliver Kayes, Majid Shabbir, David Ralph & Suks Minhas
doi:10.1038/nrurol.2012.150
Nature Reviews Urology 9, 499-507 (2012)
In this Review, Kayes and colleagues discuss the aetiology, diagnosis and treatment options for congenital micropenis, acquired micropenis and penile dysmorphic disorder, including both nonsurgical and surgical techniques. They evaluate the role of phalloplasty and penile replacement surgery including transplantation, in this challenging clinical area.
Emerging tools for erectile dysfunction: a role for regenerative medicine
Lukman Hakim, Frank Van der Aa, Trinity J. Bivalacqua, Petter Hedlund & Maarten Albersen
doi:10.1038/nrurol.2012.143
Nature Reviews Urology 9, 520-536 (2012)
Men with erectile dysfunction (ED) that is unresponsive to available oral pharmacotherapy with PDE5 inhibitors represent a significant subgroup of patients with the disorder. Such patients might in the near future benefit from regenerative medicine options that restore tissue integrity and signalling in penis-projecting neurons, penile smooth muscle cells and endothelial cells. In this comprehensive Review, the authors discuss the current cutting-edge research in regenerative medicine for ED and consider the therapeutic potential of these techniques for the future.

Challenges in sexual medicine
Selim Cellek & Annamaria Giraldi
doi:10.1038/nrurol.2012.134
Nature Reviews Urology 9, 537-542 (2012)
Sexual medicine represents one of the newest medical specialties—indeed it has only recently been recognized as a specialty in its own right. Although research in sexual medicine is at the cutting edge of some of the newest techniques, obstacles remain. Here, Cellek and Giraldi discuss the challenges faced by sexual medicine as a field, including funding difficulties, taboos and female sexual dysfunction.
