Green tea boosting my libido quite a bit (had no libido before)

Post  chipdouglas on Tue Feb 09, 2010 2:30 am

I've had no libido for the past 11 years. Recently, I've started having green tea, and noticed quite a boost in sex drive and erectile ability. I cannot recall having such firm powerful and sustained erection even back when I was 17. This alone tells me something has been awfully wrong with me for a long time.

I've tried L-theanine (Suntheanine) and I sometimes get a little boost, but clearly not as powerful as when I brew green tea. Yesterday I had two cups over the day, and the I got crazy with desire.

Now, I'm very inquisitive, and I'm trying to figure out what's behind this. I thought of COMT inhibition. It could be the caffeine, but then when I have regular coffee, I do not get this type of outcome at all. It might be increased theanine bioavailability in green tea.

If anyone has any solid hint, so far as the most likely possibilities, I'd really like to know. Having found something that works for me, clearly isn't enough, I want to know what's behind this.

Much thanks

chipdouglass - L-theanine found in green tea stimulates your brain's production of alpha waves.

BTW, if you haven't already tried ecklonia cava (fibroboost), it will also do this.

I would guess it is the synergism of the calming theanine and stimulating caffeine. Although caffeine is a vasoconstrictor and that's counter intuitive. The results must come from the CNS stimulation. Depressants like alcohol can cause ED while stimulants like cocaine are notoriously pro-sexual. Now that I think about it...It is probably the increase in dopamine from the caffeine, combined with the calming theanine. That must be why either one alone don't produce the same effect for you.

I'm intrigued, because in 11 years, it is the single most powerful response I've gotten from any thing I've tried. It definately is pointing me in the right direction.

I've been seeing an acupuncturist who's had me on this liquid formula that contains : panax ginseng, radix polygoni multiflori, herba cistanches, semen cuscutae, fructus corni, cortex eucommiae, radix morindae officinalis, fructus psoraleae, radix achyranhis bidentate, radix ploygalae, herba cynomorii.

In TCM, it's a kidney yang formula. I've been taking it for close to a month now, and it's not doing a thing. Actually, it either makes me drowsy or increase inner tension/unrest. Same acupunturist is puzzled at my response from green tea. He told me to let that formula do it's thing, but what puzzles me is that green tea does far more than the above formula when I have it, and it doesn't need three weeks to kick in. I'm going to use up those two packs I've left, and then move on. It annoys me when the so-called professional doesn't seem to figure out what's wrong. And that's not cause the man isn't qualified--he sure is proficient in his field, he worked in China for many years and he learned there as well, so there's no doubt he's qualified. However, I have this feeling TCM isn't going to cut it for me.

Back to green tea now. It's known to inhibit COMT http://en.wikipedia.org/wiki/Catechol-O-methyl_transferase.
I figure that it might possibly be connected to the benefit I get from green tea.

Now, what is known to cause increased COMT activity ?

From the above Wiki link, this part got my attention the most :


The val158met polymorphism
Main article: Rs4680
Val158Met (rs4680), a functional single nucleotide polymorphism (a common normal variant) of the gene for catechol-O-methyl transferase, has been shown to affect cognitive tasks broadly related to executive function,[2] such as set shifting, response inhibition, abstract thought, and the acquisition of rules or task structure.[citation needed] This polymorphism in the COMT gene results in the substitution of the amino acid valine for methionine at codon 158, thus the name Val158Met for the polymorphism. It has been shown that this valine variant catabolizes dopamine at up to four times the rate of its methionine counterpart, resulting in a significant reduction of synaptic dopamine following neurotransmitter release, ultimately reducing dopaminergic stimulation of the post-synaptic neuron. As a consequence, neurons with valine-variant COMT show higher levels of activation during certain cognitive tasks, as they require higher levels of neuron firing to achieve the same level of post-synaptic stimulation.

The link between impairments in these sorts of cognitive tasks and the COMT gene is thought to be mediated by an effect on dopamine signaling in the frontal lobes.

Comparable effects on similar cognitive tasks, the frontal lobes, and the neurotransmitter dopamine have also all been linked to schizophrenia. It is not surprising, then, that an inherited variant of COMT is thought to be one of the genetic factors that may predispose someone to developing schizophrenia later in life, naturally or due to adolescent-onset cannabis use.[3]

I'm a decent minded guy and was wondering how you guys can read all these medical reports and understand what they are talking about? I have been out of school for awhile and lost most of the meanings to these terms. Do you have just constantly research, any tips or websites for the layman possibly? thanks

I'm doing a bachelor degree in nursing, and all of the biology/physiology/neurophysiology etc are helping so far as the basis of things that are discussed on here. The rest, I just research over the web.

Others on here have researched a heck of a lot for years on end. It takes time.

Hey Chip,

Just out of curiosity because I was going to go into the medical field before... How do you plan an avoiding all the crap that they make employees do at the hospital- mainly all the vaccinations and flu shots? Or do you just plan on letting them give you all of it? I think I remember seeing on the news that some nurses were refusing to take n1h1, and were suspended for a while. I worry about people losing their jobs over that in the future.

I hear you regarding all of that crap. You're being told : ''no one is going to force you to get those shots''. Hey, next thing you know, you're getting a lot of peer pressure, and you're told that you put patient's life in jeopardy and so on and so forth. Last year I got the flu shot, and this year I got that darn H1N1 shot as well. I'm doing this because I'm in training. However, after I graduate, I'll turn those shots down, like nurses friends of mine do. Even many docs, don't like being pressured into getting flu shots, because they're already forced to getting plenty of other vaccines.

In all of the published papers - fuck the mumbo jumbo - just read the text tagged "Conclusion" towards the end. Reread a few times until you being to memorize some of the jargon, that's when you get it my friend....

Sorry for bumbing an older thread but has anyone considered the possiblity that when green tea is used alone (i.e. something that doesn't also inhibit 5ar 2 like the soy isoflavone genistein) it will increase the amount of DHT that is synthesized via the type 2 5 alpha reductase enzyme? If I'm not mistaken, the type 2 5ar enzyme is the one that is most responsible for serum DHT (finasteride slashes serum DHT by 70% and it only inhibits type 2) while the type 1 is primarily responsible for DHT in the skin and brain.

Seems to me when one of the 5ar enzymes is inhibited, more testosterone will be converted to DHT and estradiol. However I've read several times that Green tea also lowers estradiol (by what mechanism I'm not quite sure, it's not an aromatase inhibitor is it?) so it makes perfect sense to me how using green tea alone could possibly increase serum DHT which could be responsible for the OP's increased libido. Thoughts?

baller234 - Actually, no.

Most green tea supplements are standardized for EGCG, which does inhibit DHT (Biochem Pharmacol. 2002 Mar 15;63(6):1165-76.), however green teas primary mechanism for hair benefit is probably its effect on histamine (Arch Biochem Biophys. 2008 Aug 15;476(2):133-8.).

Also as far as why it is boosting libido for chipdouglass, he is a special case and am familair with his history. I believe it is the L-Theanine in the green tea and its effects on alpha waves and how it may elevate libido in persons whose neurotransmitter is weighted heavily towards the dopamine side.

i think i noticed this as well, when drinking green tea back when i was on saw pal and beta sis for about3 months in, everytime i drank green tea, that day i would have powerful erections like ive never had in a while, but i dont know what the reason for that could have been.

Doesn't green tea or rather EGCG more specifically only inhibit 5 alpha reductase type 1? Also, by what mechanism does it lower estradiol?

thx
