Study Lays Bare the Physiology of Erection


Staff member
The physical and psychological triggers underlying penile erection are fairly obvious. What happens at the physiological level, however, has proved harder to discern. To that end, study results published today in the Proceedings of the National Academy of Sciences will no doubt prove insightful. According to the report, the same chemical compound that causes an erection also maintains it over time. The findings could aid efforts to develop treatments for erectile dysfunction.

Building on previous work indicating that the release of the neurotransmitter nitric oxide from nerve endings in the penis produces erection, a team of Johns Hopkins University researchers led by Arthur Burnett focused on the role of the compound over time. Their research on rats and mice indicates that nitric oxide released at the onset of erection dilates the blood vessels, which enables blood to flow to the penis. That increased blood flow, the team discovered, slightly stresses the blood vessel wall, which prompts the release of more nitric oxide from the cells lining that wall, relaxing more tissue and allowing more blood to enter. The process repeats, sustaining erection.

The investigators conclude that drugs that prevent the inhibition of nitric oxide production might alleviate impotence. "The physiology of erection is like driving a car," Burnett remarks. "You can't just turn the key and expect to go anywhere. You also need to hit and hold the accelerator." --Kate Wong

I wonder if practice Kama Sutra rises our level of nitric oxide...

I will never need the drugs though...

Ah the naivety of youth. One day T.S.... One day:(
It can point to the east if you like.

I just know that one day south is where it's gonna head. :D

Usually transient don't worry

Live long (an' hard) and prosper:D

I wonder if practice Kama Sutra rises our level of nitric oxide...

Doubt it. I don't see how using the extra muscles it takes (and only the more exotic positions require that) could increase the amount of a neurotransmitter.

Besides, the Kama has a undeserved reputation, in my opinion. A great deal is devoted more to the social dynamics of sex than to sex itself.

Of course, the chapters on the correct conduct of a courtesan are delightfully cynical.

Edit to add: You kids quit flirting!
Get a room!


This is a serious thread and you two are acting like schoolgirls.
Ya know you can take erections a little too seriously dear. :eek:
I thought the boards were all about interaction.
Sometimes I think it's okay for that interaction to be a little light hearted, wouldn't you agree?

Loosen up honey you're a long time dead!:D
That was a decidedly un-serious reply on my part. You simply need to interpret tone without the emoticons.

Besides, if we have another couple proclaiming thier love all over the board I'm going to puke. :p
Sorry Xev Didn't mean to piss you off
accept this rose with my love

Not pissed. I am in a good mood. :D

(Don't know why....I shouldn't be. :bugeye: )
Course you should be you're a person with a good mind and none of the baggage that makes MY life a chore. You wanna spill, I'm a good reader?
And you call yourself christian.. Now say you're sorry!
Remember baby jesus is watching U:D
I'm just human!!
I'm just a Child of God!

Can I play, please!? :bugeye:

Sex is a common part of our Nature...

A goooooood part... :D:D:D:D

One of the things that ever most intrigued me is cyber sex... How can this be done? I can't imagine such thing...??
