ABSTRACT
Introduction. Premature ejaculation (PE) is one of the most common forms of male sexual dysfunction. The
mechanisms of PE remain poorly understood, despite its high prevalence.
Aim. To investigate the pathophysiology and casuses of PE in the central nervous system, we tried to observe the
changes in brain current source distribution by audiovisual induction of sexual arousal.
Methods. Electroencephalograpies were recorded in patients with PE (45.0 +/- 10.3 years old, N = 18) and in
controls (45.6 +/- 9.8 years old, N = 18) during four 10-minute segments of resting, watching a music video excerpt,
resting, and watching an erotic video excerpt. Five artifact-free 5-second segments were used to obtain cross-spectral
low-resolution brain electromagnetic tomography (LORETA) images.
Main Outcome Measures. Statistical nonparametric maps (SnPM) were obtained to detect the current density
changes of six frequency bands between the erotic video session and the music video session in each group.
Comparisons were also made between the two groups in the erotic video session.
Results. In the SnPM of each spectrum in patients with PE, the current source density of the alpha band was
significantly reduced in the right precentral gyrus, the right insula, and both superior parietal lobules (P < 0.01).
Comparing the two groups in the erotic video session, the current densities of the beta-2 and -3 bands in the PE
group were significantly decreased in the right parahippocampal gyrus and left middle temporal gyrus (P < 0.01).
Conclusions. Neuronal activity in the right precental gyrus, the right insula, both the superior parietal lobule, the
right parahippocampal gyrus, and the left middle temporal gyrus may be decreased in PE patients upon sexual
arousal.
Further studies are needed to evaluate the meaning of decreased neuronal activities in PE patients. Hyun

Hi
This is going to sound a bit crazy...
But I've just been checking out the teachings of this guy called Jack Grave...
And he's found a way for ANY man to go from lasting even as short as a couple of seconds in bed to over 35 minutes.
I've been looking into it and it's 100% legit.
Everything he teaches is based around the fact that if you can change what you do during sex then you can change how long you last in bed.
And he's a got a few different (really easy to use) techniques of exactly what to do to last longer.
It's not something that's normally talked about, but more men than you can imagine have to deal with not lasting long enough to please their partners...
And Jack Grave has come up with some very simple strategies for changing that.
He's posted a video on his website that explains the techniques he used to go from lasting less than 10 seconds in bed to over 35 minutes...
And at the moment it's available to watch for free.
I'm not sure how much longer it's going to be up there so I recommend you go check it out now.
You can find it at... How To Last Longer In Bed (Step-By-Step Method)
I've checked Jack Grave out and like I said he's the real deal and his stuff works. This free video is well worth a quick watch.
All the best,
