Male ejaculation has two distinct phases, emission and expulsion. Orgasm, a feature perhaps unique in humans, is a cerebral process that occurs, in normal conditions, along with expulsion of semen. Normal ejaculation is a highly coordinated physiological process with emission and expulsion phases being under the control of autonomic and somatic nervous systems respectively. The central command of ejaculation is located at the thoracolumbar and lumbosacral levels of the spinal cord and is activated by stimuli from genital, mainly penile, origin although cerebral descending pathways exert both inhibitory and excitatory regulatory roles. Cerebral structures specifically activated during ejaculation form a tightly interconnected network comprising hypothalamic, diencephalic and pontine areas.
Passion Rx for stronger ejaculation ---
Formulated by Ray Sahelian, M.D.
Works in Men and Women
Passion
Rx is a bestseller
How quickly does Passion Rx work?
Passion Rx provides results that are sometimes seen within hours, but
are more noticeable by the third of fourth day of use. Our feedback
thus far indicates more than 80% user satisfaction by the end of the first week,
and 90 percent by the end of the second week.
Dr. Sahelian and his research staff have tested various doses and extracts of
dozens of herbs from a number or raw material suppliers to determine
the ideal dose and combination for optimal aphrodisiac properties with the fewest side
effects. After years of trial and error, a proprietary
blend with more than a dozen herbal extracts from the best raw material suppliers has been created
that helps induce stronger ejaculations. This
unique aphrodisiac blend is a
close kept secret. You will only find this exact combination in Passion Rx.
Ejaculation neurotransmitters
that delay ejaculation
Several neurotransmitters contribute to the
male ejaculation process. Amongst them,
serotonin has received
strong experimental evidences indicating its inhibitory role in the central
control of ejaculation. In particular, 5-HT1A cerebral autoreceptors but also
spinal 5-HT1B and, in a lesser extent, 5-HT2C receptors have been shown to
mediate the effects of 5-HT on ejaculation. Selective serotonin
reuptake inhibitors (SSRIs) increase the amount of central serotonin
and delay ejaculation in humans. So does 5-HTP, a serotonin
precursor.
Cause of premature ejaculation
About 20 to 30% of men have premature ejaculation. The cause of premature
ejaculation remains to be clarified, but current evidence reflects a shift from
psychological reason to more neurobiological causes. Hypersensitivity of the
penis or head of penis does not appear to be a cause of premature ejaculation.
There are those who have suffered with premature ejaculation from the onset of
their sexual life while others developed this problem later on. The latter case
is called secondary premature ejaculator.
Premature ejaculation cure
Premature ejaculation is a common sexual problem and many men search for a
natural solution to prevent premature ejaculation. Preventing
premature ejaculation with 5-HTP,
a supplement that converts into serotonin, is one option. Kava capsules taken an
hour or two before sex may also be tried. Another option is to use an anesthetic
cream on the head of the penis to reduce sensation.
Premature ejaculation treatment
Five main treatment approaches have been used
in clinical trials to stop premature ejaculation: behavioral therapy,
antidepressants, phosphodiesterase-5 (PDE5) inhibitors, topical anaesthetic
agents and alpha-blockers. Most antidepressants appear to delay ejaculation to
some extent at all doses. Anesthetic creams appear to be as successful in
slowing ejaculation as antidepressants without systemic side-effects, although
some patients do experience erectile problems or unpleasant local symptoms.
Anecdotally, behavioral therapy for pre mature ejaculation is effective and appears to have long-lasting
efficacy. You can delay ejaculation by not stimulating the penis too much or
taking 5-htp, kava, or SSRIs.

Retrograde ejaculation
Retrograde ejaculation occurs when semen flows to the bladder instead of
emerging through the penis during orgasm. Retrograde ejaculation isn't harmful.
But it can impair fertility. During normal ejaculation, the opening of the
bladder (bladder neck) closes to prevent semen from entering as it passes
through the urethra. In retrograde ejaculation, the bladder opening doesn't
close properly. As a result, sperm is allowed to enter the bladder instead of
being ejected out the tip of the penis. Causes of retrograde ejaculation include
prostate surgery, bladder surgery, diabetes, multiple sclerosis, and certain
medications such as psychiatric drugs and medications used to treat high blood
pressure and prostate enlargement.
Pre ejaculation
A woman can get pregnant even when ejaculation doesn't occur within the
vagina. This is because pre-ejaculation fluid may contain some sperm. Withdrawal
of the penis from the vagina before ejaculation is one of the oldest methods of
birth control but pregnancy can occur in a small percentage of cases due to the
pre ejaculation fluid.
Male ejaculation problem
The time from initiating sexual activity to ejaculation varies from one
individual to another. This time period is called the ejaculatory latency. What
may be an ejaculation problem for one man may be acceptable to another.
Typically, ejaculation disorders fall into two categories. These are: delayed
ejaculation and early ejaculation. In the vast majority of cases, the most
effective therapeutic approach for ejaculatory dysfunction is a combination of
biologic and psychologic therapy. From an emotional standpoint, it is important
to understand the history and background of the individual. Issues such as
depression, anxiety, past sexual experiences, psychological trauma and
relationship history are important considerations that need to be discussed
early in the evaluation.
Types of male ejaculation problems include the following:
premature ejaculation, inhibited ejaculation, anejaculation, retrograde
ejaculation and anorgasmia.
Ejaculation problem due to drugs
Using Flomax (tamsulosin) every other day, rather than every day, appears
to reduce the ejaculation problems that can occur with the drug. Given that the
drug's effectiveness is not compromised with intermittent therapy, this dosing
may become the standard for all men. Drugs such as Flomax are used to treat
urinary symptoms related to an enlarged prostate -- a condition known as benign
prostatic hyperplasia (BPH). Typical BPH symptoms include difficulty in starting
to urinate, having a weak urinary flow, and the need to urinate urgently or
frequently. However, Flomax can cause ejaculation abnormalities.
Vaginal ejaculation
Vaginal ejaculation is fluid that comes out of the urethra (pee tube)
which originates not from the bladder but from the Paraurethral and Skenes
glands (located under the g-spot area).
Female Ejaculation - Woman Ejaculation
In a woman, the Grafenberg zone is a sexually arousable zone in the front part of the
vagina, stimulation of which can lead to the discharge of liquid from the
urethra, a phenomenon which is described as female ejaculation. Since the 1980s
the so-called Grafenberg zone, popularly termed "G-spot", and female ejaculation
have been controversially discussed medically as well as in popular magazines.
Male Ejaculation control
Lack of male ejaculation control is one of the top concerns of many men
under the age of 50. Concerns range from the man who ejaculates within seconds,
at the first touch, just prior to penetration, or immediately after penetration.
In these male ejaculation control cases, 5-hydroxytryptophan may be helpful.
Increase ejaculation volume
One can increase ejaculation volume by eating more cold water fish,
taking fish oil capsules, or using certain aphrodisiac herbs such as tongkat ali,
horny goat weed, or maca.
Prolong ejaculation
You can prolong ejaculation by not stimulating the penis or vagina beyond
a certain point.
Painful ejaculation
Painful ejaculation may occur due to the use of certain prescription
drugs such as antidepressants -- the tricyclic antidepressants (TCAs, e.g.
clomipramine, imipramine, desipramine, protriptyline, amoxapine), the selective
serotonin reuptake inhibitors (SSRIs, e.g. fluoxetine), venlafaxine and the
MAOIs. Apart from lowering the dose and changing the antidepressant, no
strategies are available to treat this side effect.
Prostatitis or inflammation of the prostate can also
cause painful ejaculation in a man. Ejaculation pain may also occur with some
infections that are sexually transmitted.
Ejaculation questions
Q. Is female ejaculation orgasm possible?
A. A woman can ejaculate, but not all women are able to ejaculate
during orgasm. Feminine ejaculation is not overly common.
Q. How can I increase my penis ejaculation? I am
looking for a huge ejaculation. Are herbs such as
tongkat ali and
yohimbe helpful in penis
ejaculation or
sexual enhancement?
A. If you mean how you can increase ejaculation fluid, fish
oils and eating fish such as salmon or halibut, or shellfish can be helpful.
There have not been studies yet with tongkat ali to know whether it increases
penis ejaculation volume, but some people say their ejaculation is more intense.
In a dog study, yohimbe administration led to a
big ejaculation. The big ejaculation lasted several hours after the
administration of the yohimbe bark
extract.
Q. My ejaculation is delayed. Is retarded ejaculation a
common problem?
A. Delayed ejaculation is not as common as premature
ejaculation although delayed ejaculation becomes more common as we age. I don't
see the term retarded ejaculation used much.
Q. What's the difference between ejaculation and
orgasm? Also, is a first ejaculation more intense that subsequent ones? Are
there herbs that increase
ejaculation distance?
A. Ejaculation is the discharge of fluid while orgasm
is the climax of the pleasurable physical and psychological response to
prolonged sexual stimulation. An orgasm is often accompanied by a large
ejaculation volume, blushing or spasm. An orgasm could occur with little
ejaculation volume or without ejaculation, but most often there is plenty of
fluid that is ejaculated. First ejaculation can be intense, but others in the
future can be just or more intense than a first ejaculation. It is possible that
Passion Rx or tongkat ali use could increase ejaculation distance.
Q. I have a weak ejaculation. Are there herbs that can
be helpful? Also for better
libido.
A. Certain herbs could help with weak ejaculation, some
that come to mind include yohimbe and tongkat ali.
