A new study conducted by researchers at the University of Chicago suggests that a woman’s ability to reach orgasm is partly due to her genes.According to ABC Online, the team led by behavioural geneticist Dr Khytam Dawood asked more than 3000 female twins from the Australian Twin Registry how often they achieved orgasm in different situations.They included while masturbating, while having penetrative sex with a partner; or having sex with a partner involving other methods, like oral sex.The people in the study included genetically identical twins and non-identical twins, with the difference between the two shedding light on the contribution of genes versus environment on behaviour.The researchers found that when women try to reach orgasm through masturbation, 51 percent of their chance of success depended on their genes. But for other methods of reaching orgasm, environmental factors were more important than genetic factors.When they had penetrative sex, genes accounted for just 31 percent of their chance of success, and 37 percent when a women and her partner used other methods.
