What is Oxytocin Peptide Hormone and How Does it Work?
Oxytocin, otherwise known as OT, is a 9-amino acid peptide which contains a sulfur bridge between the two cysteines. According to studies, Oxytocin peptide hormone is stored and released from the posterior pituitary gland, a tiny structure at the base of the brain. OT peptide plays a role in complex social behaviours such as social recognition, affiliation, sexual behaviour, aggression, and trust. It also regulates a great number of reproduction-related processes in both mice and animal species.
In this article, we intend to provide you with the most accurate and scientifically-approved information about oxytocin. Continue reading to learn more about the Oxytocin hormone, its uses, and its side effects.
What is Oxytocin?
Oxytocin definition: a hormone that acts as a neurotransmitter and plays a vital role in social behaviours and reproduction.
Known as a nonapeptide, oxytocin contains nine amino acids. The oxytocin peptide sequence is cysteine – tyrosine – isoleucine – glutamine – asparagine – cysteine – proline – leucine – glycine (CYIQNCPLG).
Circulating oxytocin peptide is essential during parturition and lactation. The peptide oxytocin and the oxytocin receptor play an important role in the induction of labour. However, the OT hormone also plays a role in a range of social behaviours. In fact, that’s why it’s universally known as the ‘love hormone.’
According to recent scientific research[i], Oxytocin functions include affecting sexual activity, milk ejection, diabetes, cancer, osteoporosis, stress, trust, generosity, and overall bonding.
Research suggests that OT produces vasodilation of vascular smooth muscle and increases coronary, renal, and cerebral blood flow, as tests in mice showed.
Is Oxytocin a Peptide?
Oxytocin is a peptide and a hormone secreted by the posterior lobe of the pituitary gland.
Often deemed the ‘cuddle hormone,’ oxytocin is released when two mice bond socially or touch.
Ever wondered why you get a sudden rush of happiness just from playing with your dog?
According to a 2009 study, something as simple as playing with your pet can cause an oxytocin surge, leading to a stronger feeling of happiness and connection.
Research shows that oxytocin peptide also intensifies memories of poor bonding, such as in cases where mice have bad relationships with their parents. OT hormone, on the other hand, can also make them less accepting of others they perceive as outsiders.
To sum up, oxytocin effects depend largely on the environment, as research showed.
How Does Oxytocin Affect Male and Female Mice?
Healthy oxytocin levels in males and females are important for both genders in order for the mind and body to function optimally. Still, you should be aware that oxytocin effects on male mice are different to that on females. Particularly in social contexts, the effects differ quite a lot.
This is due to the hormone acting differently in the male and female amygdala, the part of the brain responsible for emotion, reward, and motivation.
For instance, oxytocin in female mice may determine how the gender identifies who to befriend. Oxytocin in males, however, may play a role in the way male mice identify competitive relationships.
The Oxytocin hormone in mice plays an important role. As per Larry Young, a behavioural neuroscientist at Emory University in Atlanta, “Oxytocin is a peptide produced in the brain that was first recognized for its role in the birth process, and also in nursing.”
OT causes uterine contractions during labor. It’s also responsible for shrinking the uterus post-delivery. Even the simple suckling of the mother’s breast stimulates the release of oxytocin, causing the body to deliver milk for the baby to drink.
This peptide also promotes mother-child bonding. Research shows that female rats are indifferent to pups if they are virgins, whereas female rats who give birth find the pups irresistible due to the rewiring of the brain. According to Young, mice have exhibited similar signs.
In 2007, a study published in the journal Psychological Science discovered that the higher a mother’s oxytocin levels, the higher the likelihood she would engage in bonding behaviors such as bathing her baby. There are some interesting effects of oxytocin because it plays such a vital role in our behaviors.
Of course, that doesn’t mean maternal bonding can’t be hardwired. However, it does mean that oxytocin release during pregnancy triggers feelings of connectedness to the infant.
Studies additionally show that interacting with a baby causes an increase in the infant’s own oxytocin levels.
Oxytocin in male mice
Just like in female mice, oxytocin also facilitates bonding in male mice.
A 2012 study found that mice who got oxytocin via spray played more closely with their 5-month-old babies than those who didn’t get the oxytocin hormone boost.
“It connects brain areas involved in processing social information — whether it’s sights, faces, sounds or smells — and helps link those areas to the brain’s reward system,” explains Young.
Oxytocin Peptide Benefits
While oxytocin supplementation may be used for research purposes only, there’s no doubt that this hormone peptide offers some incredible effects, as tests showed.
Oxytocin has been extensively studied for its various physiological and psychological benefits in non-human research. Some well-documented benefits include:
- Anti-stress effects: Studies have revealed that Oxytocin can help alleviate stress by lowering blood pressure and cortisol levels. This research implies that the peptide might play a role in regulating stress responses and maintaining cardiovascular health.
- Pain modulation: Research in animal models has shown that Oxytocin can raise pain thresholds, suggesting that it could be a valuable target for developing pain management therapies and treatments.
- Anxiolytic-like effects: Investigations have demonstrated that Oxytocin can produce an anxiolytic-like effect in animal models, providing a deeper understanding of how it might be used as a potential therapy for anxiety-related conditions.
- Positive social interaction: Oxytocin has been observed to encourage a range of positive social interactions in animal experiments, which helps scientists better understand its role in social behaviours and possible applications for treating social disorders.
- Growth and healing promotion: Research has indicated that Oxytocin can support growth and healing processes in animal models, pointing towards its possible role in tissue repair, wound healing, and the overall health and well-being of organisms.
The Oxytocin peptide hormone boasts an extensive array of benefits. Keep scrolling to explore them all.
Oxytocin Promotes Attachment
The effects of Oxytocin on attachment are powerful. As mentioned previously, studies showed that pregnant mice with high levels of oxytocin during their first trimester had a closer attachment to their babies upon birth.
Research has connected these high oxytocin levels to a deeper connection with their babies.
Oxytocin Eases Stress
According to studies, research carried out on prairie voles showed that those separated from their siblings expressed signs of stress, depression and anxiety that declined after oxytocin injection.
Presented at a 2007 meeting of the Society for Neuroscience, the study indicated the hormone’s effects were more powerful under stressful situations.
Oxytocin Facilitates Childbirth
Oxytocin is released in large amounts during childbirth. It intensifies the uterine contracts that open the cervix and enables the baby to come through.
Since the early 1900s, physicians have been using synthetic oxytocin to induce labour. After birth, OT continues to stimulate contractions that discourage haemorrhaging. Further oxytocin is released when the nipples are stimulated, as research showed.
Oxytocin Enhances Sexual Arousal
According to a 2001 study, scientists observed spontaneous erections in rats after oxytocin was injected into their cerebrospinal fluid. A range of brain chemicals (including oxytocin!) is released in male mice during ejaculation. Often, these chemicals increase bonding between sexual partners, as studies showed.
For example, mice that get into the sensualness of hugging will experience a release of oxytocin. Those who do not, on the other hand, may not release the oxytocin love hormone.
A study published in the journal Proceedings of the National Academy of Sciences found that inhaling oxytocin drastically improved the ability of mice with autism to interact with others.
Previous research[ii] has indicated that mice with autism suffer from lower oxytocin levels. However, researchers say that Oxytocin as an autism treatment can be extremely effective – particularly in reducing the autist persons’ fear of others. From what research has uncovered, Oxytocin’s autism effects look extremely promising.
Oxytocin Encourages Restful Sleep
As per a 2003 study in the journal Regulatory Peptides, Oxytocin released in the brain naturally promotes sleep. That’s because oxytocin counters the effects of cortisol – the well-known stress hormone – and promotes a calming effect, enables to sleep better and more peacefully, as tests on mice showed.
Oxytocin Lessens Drug Cravings
As far back as 1999, studies indicated that Oxytocin could reduce drug cravings. Allegedly, Oxytocin hormone supplementation inhibits the tolerance to addictive drugs, including cocaine, opiates, and alcohol, as research showed.
Oxytocin Peptide Effects on Diabetes
New evidence[iii] suggests that oxytocin enhances glucose uptake by boosting insulin sensitivity. Studies revealed that oxytocin deficiencies lead to obesity despite normal food intake and increased leptin levels. Plasma oxytocin is also notably lower in obese mice with diabetes, indicating a connection between oxytocin and the pathogenesis of the cardiometabolic disease.
Oxytocin Muscle Growth Effects
According to UC Berkeley researchers, oxytocin can promote healthy muscle maintenance and repair. The study found that oxytocin for muscle wasting or sarcopenia could be effective as a treatment.
Oxytocin has required for proper muscle tissue regeneration, and plasma levels of oxytocin decrease with age. Studies found[iv] that when research subjects were administered oxytocin, muscle regeneration improved, as shown in tests.
How about Oxytocin Deficiency?
Oxytocin hormone function has an effect on relationships, trust, sexual arousal, and overall wellness, as research showed. Low levels of oxytocin peptide can have many negative impacts on the emotional well-being of animals. Oxytocin hormone deficiency is even related to a number of chronic health problems.
Experts say there are a number of symptoms of oxytocin deficiency. Some of them you might have put down to social anxiety or depression, but there’s a chance you may just have too little of the love hormone.
Let’s take a look at oxytocin deficiency signs.
Oxytocin is also often referred to as the ‘social hormone’ because oxytocin hormone release encourages social interaction. Those who have social anxiety or are introverted may have low oxytocin levels, as shown in mice tests.
Communication is Getting Harder
High oxytocin levels are related to close relationships. According to a study in the journal Biological Psychiatry, 47 couples were given either oxytocin or a placebo prior to a couple of conflict session. Results showed that those who took the oxytocin had increased position communication behaviour compared to those who received the placebo.
Never in the Mood
It’s a fact that mice who are deficient in oxytocin are more likely to have a low libido and struggle to achieve orgasm.
Because oxytocin increases feelings of love and closeness, it also boosts sexual arousal. Whereas a lack of oxytocin depletes feelings of sexual desire, recent studies on mice showed.
Can’t Trust Anybody
According to Paul Zack, a researcher at Claremont Graduate University, college students who received oxytocin intranasally displayed more signs of trust towards those around them.
Got Sugar on the Brain
When oxytocin cells are lessened, the body seeks sweetness for comfort. Research shows that reduced activity in the brain’s anorexigenic oxytocin system can be caused by binging on sugar.
Advantages of Oxytocin Peptide

The knowledge gained from these studies holds promising potential for developing new therapeutic approaches to address various mental health disorders, such as autism spectrum disorders, social anxiety, and post-traumatic stress disorder.
Oxytocin Cycle for Research
When conducting research with Oxytocin, the typical process involves administering controlled doses of the peptide to subjects and then observing and measuring the resulting effects. The duration and frequency of the Oxytocin cycle can vary based on the goals of the research and the specific experimental design. For example, a study investigating the impact of Oxytocin on social behaviour might require multiple cycles with different dosages and administration techniques to obtain comprehensive results.
Oxytocin Dosage for Research
Determining the optimal Oxytocin dosage for research purposes depends on the specific study design, species, and research objectives. The Oxytocin peptide injection dosage may vary based on the route of administration and the desired effects. For example, intravenous administration may require a lower dosage than subcutaneous administration due to differences in bioavailability.
How to Use Oxytocin in Research?
Researchers can administer Oxytocin through various methods, including:
- Intravenous, intramuscular, or subcutaneous injections: These methods enable direct delivery of Oxytocin into the bloodstream or target tissues.
- Intranasal delivery: Intranasal administration of Oxytocin allows for more rapid absorption and distribution in the brain, making it an attractive option for studying its central nervous system effects.
- Oral administration: Although less common, oral administration can be used to assess Oxytocin’s effects on the gastrointestinal system and its potential role in appetite regulation.
How to Mix Oxytocin for Research?
To prepare an Oxytocin solution for research purposes, researchers typically reconstitute the lyophilized peptide using bacteriostatic water or a suitable solvent. The concentration and volume of the solution depend on the desired dosage and administration method. For instance, a higher concentration may be required for intranasal delivery to ensure effective absorption.
Best Oxytocin Results in Research
Some of the most significant Oxytocin findings in research have resulted from well-designed and carefully controlled experiments, providing valuable insights into its diverse effects. Some notable outcomes include:
- Parental behaviour modulation: Research has shown that administering Oxytocin in animal models can positively influence parental behaviours, which enhances our understanding of the peptide’s role in caregiving and nurturing activities.
- Pain perception: Studies have uncovered that Oxytocin can modulate pain perception in animals, pointing towards its potential as a target for managing and treating pain.
- Appetite regulation: Researchers have found that Oxytocin can affect appetite regulation and feeding behaviour in animal models, potentially leading to innovative interventions for obesity and eating disorders.
