Final answer:
Erectile dysfunction affects a significant proportion of men, increasing with age and potentially linked to various physiological and psychological factors. Addressing medication use can often identify potential causes. Treatment typically begins with prescription drugs like Viagra or Cialis and may escalate to devices if necessary.
Step-by-step explanation:
Erectile dysfunction (ED) occurs when a sexually mature individual cannot regularly and repeatedly obtain or maintain an erection. It is a significant problem, affecting about 40 percent of men at age 40, increasing to nearly 70 percent at age 70. Alongside aging, potential causes include but are not limited to diabetes, cardiovascular disease, psychiatric disorders, prostate issues, medication side effects, especially from drugs like certain antidepressants, and low testosterone levels resulting from testicular problems.
The question of what could be causing a person's erectile dysfunction should consider various physiological and psychological factors. Addressing the use of medications, such as antihypertensives, antidepressants, or illicit drugs, as in option C) of the question, is often necessary since these substances can interfere with the blood flow or nervous control required for an erection.
Treatment for ED can range from lifestyle changes like quitting smoking and increasing exercise to medical interventions. Prescription drugs, such as Viagra® or Cialis®, are common first-line treatments. These drugs work by increasing blood flow to the pe_nis. In cases where medications are not sufficient, other options may include vacuum pumps or penile implants.
