Comparing urine levels of oxytocin and a related hormone called vasopressin in biological and adoptive children who lived in Russian and Romanian orphanages, researchers found that oxytocin rose in biological children after having contact with their mothers. The study, published in 2005 in the journal Proceedings of the National Academy of Sciences, showed that oxytocin levels remained static in the adoptive children in the same situation, suggesting a physiological basis for why some adoptive children have difficulty forming secure relationships.

Abstract
Trust pervades human societies. Trust is indispensable in friendship, love, families and organizations, and plays a key role in economic exchange and politics. In the absence of trust among trading partners, market transactions break down. In the absence of trust in a country's institutions and leaders, political legitimacy breaks down. Much recent evidence indicates that trust contributes to economic, political and social success. Little is known, however, about the biological basis of trust among humans. Here we show that intranasal administration of oxytocin, a neuropeptide that plays a key role in social attachment and affiliation in non-human mammals, causes a substantial increase in trust among humans, thereby greatly increasing the benefits from social interactions. We also show that the effect of oxytocin on trust is not due to a general increase in the readiness to bear risks. On the contrary, oxytocin specifically affects an individual's willingness to accept social risks arising through interpersonal interactions. These results concur with animal research suggesting an essential role for oxytocin as a biological basis of prosocial approach behaviour.

Abstract
Autism is a developmental disorder characterized by three core symptom domains: speech and communication abnormalities, social functioning impairments and repetitive behaviours and restricted interests. Oxytocin (OXT) is a nine-amino-acid peptide that is synthesized in the paraventricular and supraoptic nucleus of the hypothalamus and released into the bloodstream by axon terminals in the posterior pituitary where it plays an important role in facilitating uterine contractions during parturition and in milk let-down. In addition, OXT and the structurally similar peptide arginine vasopressin (AVP) are released within the brain where they play a key role in regulating affiliative behaviours, including sexual behaviour, mother-infant and adult-adult pair-bond formation and social memory/recognition. Finally, OXT has been implicated in repetitive behaviours and stress reactivity. Given that OXT is involved in the regulation of repetitive and affiliative behaviours, and that these are key features of autism, it is believed that OXT may play a role in autism and that OXT may be an effective treatment for these two core symptom domains. In this chapter we review evidence to date supporting a relationship between OXT and autism; we then discuss research looking at the functional role of OXT in autism, as well as a pilot study investigating the therapeutic efficacy of OXT in treating core autism symptom domains. Finally, we conclude with a discussion of directions for future research.

MALE ANORGASMIA TREATED WITH OXYTOCIN
ABSTRACT
Introduction. This is a case report on male anorgasmia that was successfully treated with oxytocin. Oxytocin is increased during arousal and peaks during orgasm. More recently, a study on humans published in Nature has shown its value in social bonding, increasing trust, and enhancing the sense of well-being.
Aim. To test the effectiveness of administering oxytocin in a case of treatment-resistant anorgasmia.
Methods. The patient underwent a biopsychosocial evaluation by a psychiatrist trained in sexual medicine and sex therapy for male orgasmic disorder, acquired type. Medical conditions, effect of substances, and psychological issues were ruled out. The patient was properly consented to using oxytocin as an off-label trial. Oxytocin was administered using a nasal spray intracoitally because of its ultra-short half-life.
Results. Oxytocin was effective in restoring ejaculation.
