Male Sexual Dysfunction

Normal male sexual function requires complex interactions among psychological, neurologic, hormonal, and vascular systems. Under the influence of proper stimulation, the acquisition and maintenance of a penile erection occur. Male sexual dysfunction includes erectile dysfunction (ED), impaired libido, and abnormal ejaculation, which occur due to aberrations in normal male sexual response. Estimates suggest a prevalence of approximately 10 to 20% in the adult male population. Thus, sexual dysfunction is a common problem in this country. This chapter focuses on several key, common components of male sexual dysfunction: namely, ED, premature ejaculation (PE), and Peyronie disease (PD). Figures include management algorithms, a graph depicting distribution of intravaginal ejaculation latency time values in a random cohort of men, and a Sexual Health Inventory for Men (SHIM). Tables list medications associated with ED, oral therapies for the treatment of PD, intralesional therapies for PD, indications for surgical correction of PD, recommended questions to establish the diagnosis of PE, treatment options for PE, and causes of delayed ejaculation, anejaculation, and anorgasmia.This chapte
