The research, which monitored over 100 women, showed no significant differences between groups in terms of complications or outcomes.
New human research suggests oxytocin influences feelings of well-being, sensitivity to advertising, trust, empathy, and reduces anxiety in stressed animals. Oxytocin is linked to happiness, resilient individuals are less likely to be depressed.
Researchers found that oxytocin selectively improves social cognitive abilities in less socially proficient individuals but has little effect on those who are more socially proficient. The study suggests oxytocin may hold potential for treating social deficits in people with disorders marked by deficits in social functioning.
Researchers found that oxytocin increases trust in reliable partners but not in potentially unreliable ones. Volunteers who received oxytocin nasal spray were more generous with computer and reliable partners than those who received a placebo.
