Estudio: descubren un parasito que aumenta la promiscuidad de las mujeres

"Infected men have lower IQs, achieve a lower level of education and have shorter attention spans. They are also more likely to break rules and take risks, be more independent, more anti-social, suspicious, jealous and morose, and are deemed less attractive to women.

"On the other hand, infected women tend to be more outgoing, friendly, more promiscuous, and are considered more attractive to men compared with non-infected controls....

Dr Boulter said the recent Czech Republic research was not conclusive, but was backed up by animal studies that found infection also changes the behaviour of mice.

The mice were more likely to take risks that increased their chance of being eaten by cats, which would allow the parasite to continue its life cycle. Rodents treated with drugs that killed the parasites reversed their behaviour, Dr Boulter said.
