of Oxytocin
Synthesized Oxytocin
What it does...
The hormone gets its name from a Greek word meaning “quick birth”
Found in mammals
Acts as a neurotransmitter in the brain
In humans, oxytocin is thought to be released during hugging,
touching, and orgasm in both sexes. In the brain, oxytocin is involved
in social recognition and bonding, and may be involved in the
formation of trust between people and generosity
In women, large amounts of this hormone are released after labor and
while breastfeeding
What does it play a role
in??
Child birth
dilating of the cervix
breast feeding
making emotional connections

The discovery of...
discovered by British pharmacologist Sir Henry Hallett Dale in 1906
The milk ejection property was described by Ott and Scott in 1910
and by Schafer and Mackenzie in 1911
The nine amino acid sequence was described by Vincent du
Vigneaud et al. and by Tuppy in 1953
Oxytocin was synthesized biochemically soon after by du Vigneaud et
al. in 1953.
Oxytocin was the very first polypeptide hormone to be sequenced and
synthesized.
Too little Oxytocin?
Labor may not come naturally
Have difficulty breastfeeding
May not have the same types of emotional
responses as others with high levels of
Oxytocin
Treating Oxytocin
Defeciency
If one has low levels of
Oxytocin doctors will inject the
hormone into a vein. Other
ways to get oxytocin include
nasal sprays containing the
hormone. Injected oxytocin
analogues are also given by
doctors to increase this
hormone level.
Too Much Oxytocin
Having abnormally high dosages of Oxytocin
can cause:

Subarachnoid hemorrhage
Increased heart rate
Decreased blood pressure
Cardiac arrhythmia and premature ventricular contraction
Impaired uterine blood flow
Pelvic hematoma
Afibrinogenonemia, which can lead to hemorrhage and death
Anaphylaxis
Nausea and vomiting
Treating too much
Oxytocin
While hugh levels of oxytocin can be very
dangerous, this rarely occurs naturally. Most
high levels are caused by injecting the
hormone into the body. Thus, the treatment of
this disorder is to let the hormone run its
course because of its very short life span once
it is in the blood stream.
Diseases relating to
Oxytocin
The inability to secrete oxytocin
and feel empathy is linked to
sociopathy, psychopathy,
narcissism and general
manipulativeness.
