Oxytocin is a hormone that helps relax and reduce blood pressure and cortisol levels. Oxytocin increases pain thresholds, has anti anxiety effects, and stimulates various types of positive social interaction. In addition, oxytocin promotes growth and healing.
The nonapeptide oxytocin, originally known to stimulate labor and milk ejection, appears to play an important role stress and pain. Oxytocin can induce anti-stress-like effects such as reduction of blood pressure and cortisol levels. It increases pain thresholds, exerts an anxiolytic-like effect and stimulates various types of positive social interaction. In addition, it promotes growth and healing. Repeated exposure to oxytocin causes long-lasting effects by influencing the activity of other transmitter systems, a pattern which makes oxytocin potentially clinically relevant. Oxytocin can be released by various types of non-noxious sensory stimulation, for example by touch and warmth. Ingestion of food triggers oxytocin release by activation of vagal afferents. Most likely, oxytocin can also be released by stimulation of other senses such as olfaction, as well as by certain types of sound and light. In addition, purely psychological mechanisms may trigger the release of oxytocin. This means that positive interaction involving touch and psychological support may be health-promoting. The social interaction of daily life, as well as a positive environment, continuously activate this system. In addition, various types of psychotherapy involving transfer of support, warmth and empathy are likely to induce similar effects, which thus contribute to the positive effects of these kinds of therapies.
Oxytocin Receptors
Oxytocin is a very abundant neuropeptide exerting a wide spectrum
of central and peripheral effects as neurohormone, neurotransmitter, or
neuromodulator. In the central nervous system, the oxytocin gene is
predominantly expressed in magnocellular neurons in the hypothalamic
paraventricular (PVN) and supraoptic (SON) nuclei. The magnocellular
oxytocin neurons release their products into the general circulation in
the neurohypophysis while the mediocellular oxytocin neurons secrete
elsewhere in the CNS. Oxytocin is also produced in peripheral tissues,
e.g., uterus, placenta, amnion, corpus luteum, testis, and heart. Oxytocin
is a potent stimulator of spontaneous
erections in rats and is involved in
ejaculation. The typical actions of peripheral oxytocin are stimulation of
uterine smooth muscle contraction during labor and milk ejection during
lactation. Oxytocin receptors have also been identified in other tissues,
including the kidney, heart, thymus, pancreas, and adipocytes.
How to increase Oxytocin levels
Ingestion of food triggers oxytocin release by activation of vagal
afferent nerves. Most likely, oxytocin can also be released by stimulation of
other senses such as olfaction, as well as by certain types of sound and light.
In addition, purely psychological mechanisms may trigger the release of oxytocin.
This means that positive interaction involving touch and psychological support
may be health-promoting.
Oxytocin and Sex
Also known as the "cuddle"
hormone, oxytocin is
released by both men and women at sexual orgasm.
Oxytocin and Massage
Oxytocin can be released by various types of sensory stimulation, for
example by touch and warmth. Bloodstream levels
of oxytocin have been shown to rise during massage.
How Oxytocin works
Oxytocin suppresses the
activity of the brain region known as the amygdala, the area that processes fear
and communicates it to the rest of the brain. A small
sample group of 15 men inhaled either oxytocin or a placebo before performing a
task in which they sorted pictures of angry or fearful faces and threatening
scenes. During the test, the researchers monitored the subjects' brain activity
with functional magnetic resonance imaging and found that the oxytocin
group indeed had reduced activity in the amygdala.
Oxytocin Reduces Fear
Animal and human studies indicate the major role of the amygdala in
controlling fear and anxiety. The amygdala is involved in detecting threat
stimuli and linking them to defensive behaviors. This is accomplished by
projections connecting the central nucleus of the amygdala to the brain stem and
to hypothalamic structures, which organize fear responses. Oxytocin tempers the
excitatory inputs into the amygdala.
Orgasm and Oxytocin Hormone
Plasma oxytocin levels increase during sexual arousal in both women and
men and are significantly higher during
orgasm / ejaculation
than during baseline testing.
Availability of Oxytocin Drug
Oxytocin is sold as oxytocin nasal spray. Oxytocin nasal spray (Syntocinon).
A nasal spray containing the hormone oxytocin, which is essential to the
production and flow of breast milk, does not improve milk output in mothers
expressing milk for preterm infants.
Intranasal administration of Oxytocin causes a substantial increase in
trusting behavior.
Oxytocin and bonding
The levels of oxytocin hormone in a pregnant woman's body play a role in how
closely she will bond with her newborn. In animals, oxytocin, dubbed "the
hormone of love and bonding," is involved in good parenting and maintaining
close relationships. Dr. Ruth Feldman and colleagues at Bar-Ilan University,
Ramat-Gan, Israel, studied the role of this hormone in humans and found oxytocin
is important in the bonding that occurs between mothers and their infants. Dr.
Ruth Feldman and colleagues measured oxytocin levels in 60 pregnant women during
the first and third trimester and the first month after delivery. They found
that initial levels of oxytocin (first trimester) predicted bonding-related
thoughts...as well as maternal bonding to the newborn. Mothers with higher
levels of oxytocin at the start of pregnancy showed more bonding behaviors after
birth. Psychological Science, November 2007.
Oxytocin hormone questions
Q. What supplements increase the production of oxytocin?
A. We have not come across such research at this time.
Q. Where can I get this Oxytocin nasal spray to
purchase? I live in Canada.
A. Your doctor should know.
Q. I have a question regarding the statement below on
oxytocin. Most likely, oxytocin can also be released by stimulation of other
senses such as olfaction, Are you aware of any research identifying olfactory
stimulants that trigger the release of oxitocin?
A. This is not my area of specialty.
Q. I am working on a story for a health magazine about
ways to boost men's mood without the use of antidepressants. I would love to
find out if men can boost their mood by having regular orgasms or sex. Are there
any feel-good, mood-boosting chemicals released during sex that might help
naturally boost a guy's mood? If so, how do they work in the body? How long do
they last to help boost a guy's mood or help him relax, etc.? What else should
men know about sex and their mood?
A. Men can temporarily improve their mood through sex and orgasms
which can last several minutes, hours, or days depending on the depth of
connection and intimacy with the partner. Oxytocin is one major hormone that is
released through orgasm and its effects normally last minutes or hours. If there
is a connection and love with the partner, the afterglow of the sexual
connection and mood lift can last a long time. However, in most men, sex is not
a reliable and consistent way to improve mood. If there is no emotional
connection with the partner, there can actually be a let down after the sexual
act. Oxytocin is secreted from the pituitary gland. Oxytocin receptors are found
in many parts of the brain and spinal cord, including the amygdala and
brainstem. It's actions and biochemistry are too complex for the average reader.
Q. Dr Sahelian: We have been reading much about you and
now learned of your article written on Oxytocin hormone. As a compounding
pharmacist we have been preparing several formulas of Oxytocin for physicians
for years. We compound an oral oxytocin tablet in our proprietary blend to
bypass the stomach and portal system to be absorbed by the lymphatics. This
provides a dose much like an injection. A poster presentation of plasma levels
reveal good levels at 3 hours after ingestion and remain increased for up to 8
hours. We also compound a sublingual oxytocin dose which provides a dose within
15 to 20 minutes. Moreover, we compound a topical Oxytocin. Anecdotal reports on
its use are multiple orgasms and better erections with more sensations when
applied to genitals. More bonding, increased cognition, better sleep and “I feel
10 years younger” when applied to the non-genital skin. So, now you have a
source of Oxytocin replacement without an injection or nasal spray. BelMar
Pharmacy,
12860 W. Cedar Dr #210, Lakewood, CO 80228. We have filed a patent on the use of
Oxytocin for certain things including multiple orgasms, male erection, bonding,
nurturing, trusting, autism, etc.
Q. I receive a spam email regarding Oxytocin
homeopathic formula. Does this oxytocin product work?
A. Oxytocin is a hormone that is not available over the counter.
Therefore, Oxytocin hormeopathic formula, in my opinion, is a scam.
Q. I am an undergraduate psychology student at Boston
University. I have recently undertaken some independent research on oxytocin and
various clinical applications. I am very interested in research on oxytocin.
A. A Medline search would offer research studies and contact info
on investigators who are researching this hormone.
I was advised by my urologist that I should try
oxytocin to address my anorgasmia, but he didn't know where or how to obtain it.
Can I obtain it through you? Do I need a prescription?
Oxytocin is not available over the counter since it is not
classified as a dietary supplement. See
better orgasm for
suggestions on natural supplements that could be helpful.
Can u send me some information on this hormone. My
husband has antisocial personality and I think it may help him bond with us. He
can express no real feelings just generic ones for dramatic effects. Please let
me know and or if it is available for me to ask his phychyatris about in a
prescription form.
