Erectile dysfunction in men in their 20s can involve performance anxiety, stress, depression, or relationship difficulties, but physical conditions, medications, and substance use can also contribute. In many cases, more than one factor is involved. Physical contributors can include hormonal problems, smoking, recreational drug use, and conditions that affect blood vessels or nerves. Pornography use may be associated with sexual difficulties for some people, but it is not established as a cause of impaired penile blood flow. Obesity can increase the risk of erectile dysfunction through its links with vascular, metabolic, and hormonal health. Sleep disorders, certain medications like antidepressants, and underlying health conditions such as diabetes or thyroid dysfunction may also contribute. Mental health factors may contribute to ED in younger men, and counseling or lifestyle changes may help when appropriate. Persistent or recurring ED should still be assessed by a healthcare professional because medications and hormonal, metabolic, vascular, neurologic, or other health conditions may be involved.
