Better language skills with regular sex
Those who had sex at least once a week did better on some of these tests. In particular, they had higher language skills than the sexually inactive participants. The more active participants were also better at drawing a complex picture and tracing a clock face from memory. However, sexual activity apparently had no influence on memory and attention. "It is possible that greater frequency of sexual activity is related to better cognitive abilities," explains research team leader Hayley Wright. The researchers now want to find out the biological cause of the connection they found. For example, they want to find out whether hormones such as dopamine and oxytocin, which are released during the sexual act, somehow affect brain function.
I have presented this study to you because I am sure you have already read or will read about it. I myself find the work interesting, but not sufficiently conclusive. Firstly, the number of 83 study participants is very small. Moreover, the age range (50-83) should not be spread quite so widely. Secondly, I think the method of determining sex frequency by questionnaire alone is too prone to error. For various reasons, some study participants are likely to under- or exaggerate on this question - at least not necessarily tell the truth. And third, in my opinion, the study does not prove at all what is cause and what is effect. Does regular sex really lead to more fluency, as the authors conclude? Or, on the contrary, does someone who is more linguistically fluent subsequently have sex more regularly? Or are the frequency of sex and fluency two independent factors caused by a third factor, for example a fulfilling social or married life, physical health, etc.? I assume that scientists are also aware of these problems and that more extensive studies will therefore follow. Until then, I think the statement: "Sex is good for the brain" is probable, but not yet sufficiently proven. On the other hand, if not for the brain, sex is certainly good for other things.
