Question

Quizplus · Accepted Answer

Erection is achieved when the penis fills with blood, so poor circulation to the penis would be the most logical cause of inability to achieve erection. Weakness or atrophy of the penile muscles may contribute to erectile dysfunction, but poor circulation is a more likely cause. Decreased functioning of the seminiferous tubules and an undescended testicle would not affect erection.
