The DNA of study subjects had been analyzed for MAOA gene variation and their self-reported happiness was scored by a widely used and validated scale.<\/p>\n<p>After controlling for various factors, ranging from age and education to income, the researchers found that women with the low-expression type of MAOA were significantly happier than others. Compared to women with no copies of the low-expression version of the MAOA gene, women with one copy scored higher on the happiness scale and those with two copies increased their score even more.<\/p>\n<p>While a substantial number of men carried a copy of the \u201chappy\u201d version of the MAOA gene, they reported no more happiness than those without it.<\/p>\n<p>So, why the genetic gender gap in feeling good?<\/p>\n<p>The researchers suspect the difference may be explained in part by the hormone testosterone, found in much smaller amounts in women than in men.\u00a0 Chen and his co-authors suggest that testosterone may cancel out the positive effect of MAOA on happiness in men.<\/p>\n<p>The potential benefit of MAOA in boys could wane as testosterone levels rise with puberty, Chen said. \u201cMaybe men are happier before adolescence because their testosterone levels are lower.\u201d<\/p>\n<p>Chen emphasizes that more research is needed to identify which specific genes influence resilience and subjective well-being, especially since studies of twins estimate genetic factors account for 35 to 50 percent of the variance in human happiness.<\/p>\n<p><strong>While happiness is not determined by a single gene, there is likely a set of genes that, along with life experiences, shape our individual happiness levels<\/strong>, Chen said. \u201cI think the time is right for more genetic studies that focus on well-being and happiness.\u201d<\/p>\n<p>\u201cCertainly it could be argued that how well-being is enhanced deserves at least as much attention as how (mental) disorders arise; however, such knowledge remains limited.\u201d<\/p>\n<p>The study by Chen and colleagues was supported by the National Institutes of Health and a USF proposal enhancement grant.<\/p>\n<p><strong>Article citation:<br \/>\n<\/strong>Henian Chen, Daniel S.
