Help with questions about erectile dysfunction?
This is from Ap Biology. What is the leading cause of erectile dysfunction? What is the second most common cause of erectile dysfunction? What is the role of Nitric Oxide in maintaining an erection?
Can you please give a thorough explanation? The book doesn’t clearly state these answers.
Chosen Answer:
There are lots of causes, but poor circulation (that comes with age) is a major one, along with high cholesterol, diabetes, fatigue, some medications, and recreational drugs. Nitric oxide is important because it is a vasodilator, allowing blood to flow into the corpora cavernosa. Viagra (and I suppose analogous meds) prevent the NO from being broken down too soon.
