Erectile dysfunction is a condition that affects a man's ability to achieve or maintain an erection suitable for sex.
The condition can affect men
at any age, but according to the American Academy of Family Physicians,
erectile dysfunction (ED) is most common when a man is 75 years or older.
Recent innovations in medical
treatments mean that there are now more medications available to reduce ED.
However, some men prefer to take herbal supplements as an alternative.
Many herbs show potential to
be effective in improving men's sexual function, but little evidence actually
exists to support the use of any herbal medication in the treatment of ED.
People should always exercise caution when taking any form of herbal
supplementation.
The United States government
do not monitor herbs. There is no consistency in the strength or purity of the
herbs sold, so they may be contaminated or mislabeled. Some herbs may interact
with medications taken, so anyone considering taking herbs should talk to a
doctor or pharmacist about potential problems.
Dehydroepiandrosterone (DHEA)
What is it: DHEA is a
supplement that mimics a natural steroid hormone in the body and may help treat
ED in men.
The dosages for DHEA vary from person to person. Some men take between 20 and 75 milligrams (mg) for about 6 months, while others may take between 100 to 400 mg for up to 8 weeks.
How does it work: Natural DHEA
levels subside as a person ages. Increasing the amount of adrenal hormone may
help the body create hormones that improve sexual functions as well as energy
levels.
Research: A 1999 study
published in the journal Urology showed that DHEA treatment improved sexual
performance. However, the study was a very small one. Since then, other
research has shown inconsistent results, with one report in 2012 suggesting
that DHEA does not help ED.
Side effects: DHEA is usually
safe when taken in low doses. However, acne can be a side effect.
Horny goat weed (epimedium)
What is it: This Chinese herb
has been used to reduce the causes associated with sexual dysfunction,
including erectile dysfunction. Women may also take it to reduce the incidence
of painful intercourse and loss of libido.
How does it work: Researchers
do not know the exact mechanism by which the supplement works. But scientists
believe it alter the levels of certain hormones in the body, which may in turn
improve sexual performance.
Research: Taking horny goat
weed hasn't been studied in people. However, a study published in The Journal
of Sexual Medicine studied the effect of a purified extract of epimedium on
rats. It found that rats who received the extract demonstrated greater
incidences of blood flow than those who did not.
Side effects: Using this herb
could affect a person's heart function. Those with heart disease should not
take it as it can cause irregular heartbeat. The medication can also interact
with other drugs.
Ginkgo
What is it: Ginkgo biloba is
an herb that practitioners have used for thousands of years to treat a number
of health conditions. Examples include dementia, anxiety, and poor blood flow
to the brain.
How does it work: Proponents
of taking ginkgo for erectile dysfunction believe ginkgo dilates blood vessels
to promote blood flow to the sexual organs.
Research: The Mayo Clinic rank
the evidence for ginkgo in treating erectile dysfunction a "C,"
meaning that there is unclear scientific evidence for the herb's use.
According to Columbia
University, ginkgo may be effective in helping treat sexual dysfunction that
has been caused by taking selective serotonin reuptake inhibitors (SSRIs),
medications prescribed to treat depression.
Side effects: Ginkgo can
increase the risk for bleeding, and people who take blood thinners should not
take it.
Other side effect risks
include nausea, headache, stomach upset, and mouth irritation.
L-arginine
What is it: L-arginine is an
amino acid that scientists in the 1800s first isolated from animal horn. It is
incorporated into supplements to increase the amount of nitric oxide in the
body.
How does it work: When taken
in high doses, l-arginine can stimulate blood vessels to become larger. This
improves blood flow, which could help a man get an erection.
Research: L-arginine is often
combined with glutamate and yohimbine hydrochloride as a treatment for ED.
In one study published in the
Journal of Sexual and Marital Therapy, researchers gave participants a
combination of l-arginine and pycnogenol, a supplement derived from pine bark.
After treatment for 3 months,
92.5 percent of the 40 men enrolled who experienced ED reported achieving a
normal erection.
Side effects: Side effects of
taking l-arginine can include stomach upset, including cramping and diarrhea.
The supplement can also adversely interact with taking the medication Viagra.
Red ginseng
What is it: Ginseng is an herb
that Korean herbal practitioners promote for its ability to treat erectile
dysfunction. Another name for red ginseng is Panax ginseng.
How does it work: Researchers
aren't exactly sure how red ginseng reduces erectile dysfunction symptoms.
One theory is that it
influences hormones responsible for achieving an erection. Another is that it
promotes blood flow through increasing the amount of nitric oxide.
Research: A 2008 review
published in the British Journal of Clinical Pharmacology found that red ginseng
was often more effective than placebo when reducing ED symptoms.
However, human studies usually
have a small sample size, which makes it difficult for researchers to draw firm
conclusions on the benefits of red ginseng.
Side effects: Taking red
ginseng can cause insomnia. However, researchers largely regard it as safe when
taken on a short-term basis.
Yohimbine
What is it: Yohimbine is a
supplement made from the bark of an African tree. Before medications such as
Viagra, doctors often recommended yohimbine as a treatment for ED.
How does it work: Yohimbine
works by triggering receptors in the body that trigger the release of the
hormones epinephrine and norepinephrine. These can block the effects of other
compounds that may otherwise constrict the blood vessels in the penis.
Research: The American
Urological Association do not recommend taking yohimbine as a treatment for ED
because of its many side effects. However, it has been shown to enhance libido
and sexual motivation in animal studies.
Side effects: Taking this
supplement is associated with many side effects. Examples include high blood
pressure, rapid heart rate, and anxiety. Men should not take yohimbe without
consulting their doctor first.
When to see a doctor about ED
Men should not be afraid to
see their doctor about ED if they experience it.
There are many medications,
lifestyle changes, and even counseling that could help a man reduce the
incidence of ED. If he wishes to, and has discussed the treatment with his
doctor, he may even wish to take an herbal supplement to reduce ED.
A man should see his doctor
about his ED if he has experienced changes in sexual desire, changes in
erectile function after taking a new medication, or other changes in sexual
function.
The condition is very treatable.
Men should never be afraid to talk to their doctor about ED as sometimes the
condition can indicate an underlying medical condition that should also be
treated.
Many potential causes of ED
exist. These include:
- anxiety
- atherosclerosis, a condition that causes a buildup of plaque in the arteries
- chronic kidney disease
- depression
- diabetes
- heart and blood pressure-related conditions
- history of injury to the penis or surrounding organs
- stress
- taking certain medications, such as antidepressants, antihistamines, appetite suppressants, and tranquilizers
Achieving and maintaining an
erection requires several things to happen. These include sensory stimulation,
increased blood flow, increased blood pressure in the penis, and the
contraction of muscles in the penis. If one or more of these steps are
interrupted, ED can occur.
