Which disorder occurs in 10-20% of all men and comprises more than 50% of all men treated for sexual disorders?

Choice A reason: Erectile dysfunction (ED) is a highly prevalent condition, especially as men age, often linked to vascular health. While it is a very common reason for seeking treatment, statistics show that premature ejaculation remains the most frequent sexual complaint across the lifespan, particularly in younger cohorts, accounting for a larger percentage of the overall clinical treatment volume for male sexual dysfunctions. Choice B reason: Male hypoactive sexual desire disorder involves a persistent deficiency of sexual fantasies and desire for sexual activity. While it causes significant distress, it is reported less frequently in clinical settings than ejaculatory or erectile concerns. It often has complex psychological or hormonal roots but does not reach the 50% threshold of all men treated for sexual disorders. Choice C reason: Delayed ejaculation is the least common of the male sexual dysfunctions. It involves a marked delay in or inability to achieve ejaculation despite adequate stimulation. Because its prevalence in the general population is quite low (estimated at less than 1%), it does not account for the high percentage of clinical cases described in the question. Choice D reason: Premature ejaculation is widely recognized as the most common male sexual dysfunction. It affects approximately 10% to 20% of men globally and constitutes over half of the cases in clinics specializing in male sexual health. It is defined by ejaculation occurring within approximately 1 minute of penetration and a lack of voluntary control, leading to significant personal and interpersonal distress.
