Alcohol makes women vulnerable, men are easy to adultery

Scientists have finally discovered why alcohol makes women soft, and men fall, betraying their wives or lovers, thanks to research in hamsters.

Researchers from Oregon Medical and Science University (USA) used hamsters to test the effects of alcohol on emotional relationships.

Hamsters are famous creatures of fidelity, often used in studies of cohesion and one-wife-monogamy in humans, because they mate for life. Unlike other animals, hamsters also like strong drinks like humans.

In the US team's experiment, hamsters were given vodka. Specifically, during the 24 hours, the male mice, which had never mated before, were allowed to stay together and drink alcohol. Next, individuals in all of these pairs were separated and captured with a new opposite sex.

The team then observed and analyzed the behavior of hamsters due to drunkenness. They found behavioral differences between males and females when they were no longer alert.

When alcohol acts on the brain, male mice become out of control, tending to be destructive. Meanwhile, the female yeast rats became more anxious and coveted leaning on the other shoulder.

Drunken male mice also show a preference for new sexual partners over the original females and tend to betray more. Meanwhile, unconscious children prefer their original partners over their new partners, and want more time to cuddle and caress with their old love. Interestingly, the opposite phenomenon happened to the collated hamster group, not to drink alcohol.

According to the team, nerve peptides associated with anxiety were influenced by alcohol, but in opposite ways in male and female mice. Males showed an increase in the density of these neurotransmitters in the amygdala, associated with reduced anxiety, while in females it was not.

Experts say that it is the reduction of anxiety that makes males more likely to hate the old and fall out of love. The opposite happened to the children.

The team concluded: "This is the first time we have demonstrated that drinking alcohol can have a direct impact on social ties , and that these effects occur in parallel with changes in nerve peptides.

That means, we can use hamsters to simulate not only human alcohol-related behavior, but also potential differences at the molecular level of those behaviors. More research is needed, but the separation between biological effects and social influences can lead to better treatments for alcoholism and personal conflicts from there. "
