Should men try ginkgo biloba?
Nitric oxide is a gas and a key signaling molecule in the human body.
It can help lower blood pressure and plays a role in rockiness.
There are also downsides to excess nitric oxide…
…and its role in male sexual function has been overplayed, mostly due to the marketing of nitric oxide-boosting treatments like little blue guys.
Researchers looking at the effect of herbal remedies on male sexual function…
…found that ginkgo biloba increased the number of times male rats had sex over 2 weeks.
The researchers were surprised that the supplement did not increase nitric oxide.
But I have an idea about why it works…
The animal experiments were performed at HungKuang University in Taiwan. This paper was published in Neuroscience Letters.
“Nitric oxide is an important messenger in the central nervous system to mediate male copulatory behavior.”
Nitric oxide can help with weak rockiness, and the researchers wanted to know whether the aphrodisiac effect of ginkgo biloba might be due to its increasing nitric oxide.
“EGb 761, a standardized extract of Ginkgo biloba, has been reported to facilitate male copulation in rats.”
The researchers looked at the effect of this ginkgo biloba supplement on an enzyme (nNOS) that generates nitric oxide in the MPOA.
This is a region of the hypothalamus that regulates male sexual behavior.
“The present study is to determine the effects of nNOS in the MPOA on copulation in male rats following EGb 761 treatment.”
Some rats were given the standardized extract of ginkgo biloba for 2 weeks.
Others were given an inactive alternative.
The researchers quantified sexual behavior before and during the experiment.
The animals were sacrificed after 2 weeks, and their brains were examined for nitric oxide activity in the target region of the hypothalamus.
Ginkgo biloba had a clear effect on sexual function.
“14 days treatment significantly increased the intromission frequency compared to the vehicle-treated controls on day 14.”
In other words, there was a notable increase in the number of times rats given gingko engaged in sexual intercourse.
The number of ejaculations over the 2 weeks also increased.
Sex and ejaculation increased from baseline and compared to the control group.
“An increase in ejaculation frequency was also seen in the EGb 761-treated group compared to the vehicle-treated controls on day 14 and to the same group on day 0.”
The researchers were surprised to find that this potent aphrodisiac herb did not affect nitric oxide in the part of the brain they believe controls sexual drive.
“However, EGb 761 treatment did not influence the number of nNOS-immunoreactive cells in the MPOA.”
Ginkgo biloba doesn’t seem to work by increasing nitric oxide.
“These results suggest that enhanced male copulatory performance in sexually experienced rats administered EGb 761 may not be related to central nNOS activity in the MPOA.”
So then, how might it work?
Let’s take a look at another study that found that ginkgo biloba…
“…significantly reduced serum prolactin levels and increased dopamine levels…”
If you read my newsletter on sex and prolactin, you know that prolactin is the primary libido-suppressing hormone.
Some studies have shown that men with very low levels of prolactin are ready to have sex almost immediately after ejaculating.
Increasing prolactin decreases sexual activity and sexual function.
The fact that ginkgo biloba suppresses prolactin can explain its aphrodisiac effects.
Ginkgo biloba also increased dopamine – something associated with drive and motivation.
Dopamine suppresses prolactin levels.
“…enhances the copulatory behavior of male rats and suggests that the dopaminergic system, which regulates prolactin secretion, may be involved in the facilitatory effect.”
Nitric oxide is involved in male sexual function, but it’s not the be-all, end-all – far from it…
—-Important Message About Prolactin—-
My PET Protocol works by naturally lowering prolactin and estrogen in a man while raising testosterone
Because here’s what happens to most guys as we get older:
…estrogen and prolactin rise, and…
….testosterone drops…
And this is the opposite of what men need for good erections, a high drive, and to last a long time in bed.
Men need estrogen and prolactin to be low, and testosterone to be high.
So that’s what the PET Protocol does — it lowers estrogen and prolactin, so testosterone can rise again.
It’s simple really, but oh so powerful.
It’s just a simple little protocol men can do at home and it’s safe enough to do every day if you want.
