Association of the Force of Ejaculation and Orgasm Satisfaction using Novel Assessment Tools: Prospective Trial in Healthy Men

Male sexual function depends on the complex interaction of multiple dimensions of human sexuality: arousal, sexual desire, orgasm, erectile function, and ejaculation. Sexual dysfunction is often multi- dimensional that occurs as a spectrum of disorders involving any or a combination of these factors [1]. Sexual dysfunction is a common problem in males with 35% of men aged 40 to 70 years experiencing moderate to complete erectile dysfunction [2], and in an analysis of more than 3000 individuals, 31% of men reported some sexual dysfunction [3]. IMajor advances have been made in understanding the neurovascular mechanisms of sexual response and function in men [4,5], with the development of several drugs for the treatment of erectile dysfunction [6]. Ejaculatory dysfunction, which includes a spectrum of disorders such as premature ejaculation, delayed ejaculation, an ejaculation, painful ejaculation, retrograde ejaculation, and diminished volume or force of ejaculation, is an important public health problem that is often comorbid with erectile dysfunction and orgasmic dysfunction [7]. Premature ejaculation can be a frequent source of distress and sexual dissatisfaction [8,9]; one study of 1,463 females found that poor ejaculatory control contributed up to 23% of their relationship terminations [10]. It is estimated that 10-20% of men will have delayed ejaculation or an ejaculation [11,12], with 20-40% of men experiencing ejaculatory dysfunction at some point in their lives [13]. Although ejaculatory dysfunction is prevalent, it has not been wellcharacterized or evaluated. Delayed ejaculation and an ejaculation do not have separate classifications in the Diagnostic and Statistical Manual of Mental Disorders IV (DSM-IV) or billing ICD-9 codes, making the study of their effects in the population difficult. There are currently no standardized assessments of ejaculatory function, and little is known about the relationship between ejaculatory force and orgasm satisfaction. This study sought to evaluate the association between ejaculatory force and orgasm satisfaction using a standardized assessment.
