INDEPENDENT NEWSPAPERS
A recent survey for online pharmacy ukmedix.com found 62 percent of men turn down sex more frequently than their female partner, with a third admitting they had lost their sex drive.
London - For men who roll over and nod off rather than engage in pillow talk, it’s the perfect excuse.
They really do need to sleep after sex because the male brain is designed to switch off at that point, scientists claim.
They scanned men’s brains before and during orgasm, and found that the cerebral cortex – or “thinking” area – shuts down.
Straight afterwards, two other areas, the cingulate cortex and amygdala, tell the rest of the brain to deactivate from sexual desire.
This is accompanied by a surge of chemicals such as oxytocin and serotonin, which can have a powerful sleep-inducing effect, according to the researchers.
Neuroscientist Serge Stoleru, who leads a group at the French medical research council Inserm, said: “These experiments give us the first hints as to what happens in the brain during orgasm. After men have an orgasm they usually experience a refractory period when they cannot be aroused.
“For women it seems to be different. They don’t seem to have such a strong refractory period and may be asking for more when their partners just want a rest.”
One of the chemicals they release is prolactin, which is linked to the feeling of sexual satisfaction. Previous research has found men who are deficient in prolactin are less tired afterwards.
Dr Stoleru, whose research is published in the journal Neuroscience and Biobehavioral Reviews, said: “The human brain is involved in all the successive steps of sexual behaviour.”
It may be a relief to some women to know there is a biological explanation for the roll-over-and-sleep effect.
Earlier this year psychologists at the University of Michigan in the US found women whose partners nod off are left feeling insecure and craving affection. - Daily Mail
