Sex steps up brain growth, study suggests

Sex apparently can help the brain grow, according to new findings in rats.

Sexually active rodents also seemed less anxious than virgins, Princeton scientists discovered.

Past findings had shown that stressful, unpleasant events could stifle brain cell growth in adults. To see if pleasant albeit stressful experiences could have the opposite effect, researchers studied the effects of sex in rats.

Scientists played matchmaker by giving adult male rats access to sexually receptive females either once daily for two weeks or just once in two weeks. They also measured blood levels of stress hormones known as glucocorticoids, which researchers suspected might lie behind the detrimental effects that unpleasant experiences have on the brain.

When compared with male virgins, both groups of sexually active rats had cell proliferation, or an increase in the number of neurons, in the hippocampus, a part of the brain linked with memory whose cells are especially sensitive to unpleasant experiences. The rats that had more sex also had adult brain cells grow, as well as a rise in the number of connections between brain cells.

However, the rodents that only saw females once in two weeks had elevated levels of stress hormones, while the rats that had regular access showed no increase in the hormones. Sexually experienced rodents also proved less anxious than virgins, in that they were quicker to chomp down on food in unfamiliar environs.

These findings suggest that while stress hormones can be detrimental to the brain, these effects can be overridden if whatever experiences triggered them were pleasant.

    To DNO

    While we understand that you have to cater to different readers, some of the material and photos being presented lately are bordering on inappropriate for the general readership and is instead pandering to certain persons based on several of the comments made. While with television, a parent can control what a child watches, it is more difficult to do so with the internet especially when a site is not expected to carry certain material. Maybe you need to introduce Pay-per-view for the visitors who need to read certain rated material. See a snapshot of the Laws of Dominica which pertain to indecent or obscene material.

    Let’s remember the children who have not been exposed to adult behaviour yet and allow them to learn it the correct way instead of hitting them over their heads with it. Also, let’s not forget that there are perverts out there looking for material to develop their bents.

    Now I see why my brain is just not growing anymore. By now I should have had a Phd, but I don’t have one. The same rats, mankind’s biggest enemy, they have got the answers for us for healthy living. We might not like them, but we resort to them for answers.

      Do people like you still exist in this world? Shocking! For your information the same teenager you are talking about whats appropriate for him or her is able to teach you some back flips when it comes to sexual activities, no maybe about that i am sure. Dont be ignorrant. We live in a world where it is better to talk openly than to keep on hiding like your great grand mother did. Grow up and come to grips with reality this is not a joking world, this is life unscripted. Do yourself a favour sit in your kids classroom without a teacher in there and you would be quite supprise with what you can learn from them.

        u people needs Jesus,

        there is a difference in Educating a child and influencing a child,let me explain
        u tell a child don’t eat candy it will help give tooth decay:this is educate there as
        u tell that very child dont eat candy it will help tooth decay BUT u know what baby it is good cause it helps give u beautiful skin.

        so u a the ignorant person,u confused that child tortally,u left that child to wonder.
        u all might just been messed up already and think u know how to raise kids.

    This is so ridiculous and using rats to compare with human beings. So much for science and researchers. :twisted: What are they also teaching the younger generation?
    I would think that people who indulge in a lot of sex are the most stupid of all. :lol: How happy are they? How happy does it make them and permanently so if that is all they can do and think about.
    Some years ago when purchasing a card I came across a card as stated:

    “I say, men who always think about sex are hard of hearing.”
    This could pertain to some women as well. :lol:

    It appears sex rules the world. The more they get is the more they want spurred on by Satan, turning “Love and making love” into a mere action with no purpose behind it, just for the sake of doing it. What next after that and how does one feel after that type of making love, eh!
    People love sex more than they love God as some will not attend Church, pray and perform good works, Works of Mercy in Jesus’ Name. Sex is their god and an addiction and having different partners.
    They may very well have a mental problem as the psychiatrist stated on a previous article.
    Consider one of the messages of the Mother of God, the Ever Blessed Virgin Mary to a visionary which is a message for us all: “Many souls go to Hell for sins of the flesh.”
    Sex within marriage is considered “making love – with the one they love and married.” Everything should be done in moderation – not overdone. Therefore, moderation is the key word and action.

    Guess there are stories and then the reality of it……because when we know better we do better…..It is clear that those scientists got PAYED!!!! truth or lie…..as we all know they are the ones who spends money developing diseases……and spend a little more to find a cure…

    Guess they think we should all behave like those brain washed rat…..but they should come better than that…..

    The ones that are too smart they use them as lab rats!!!! and tickle their brains, and those that are a less smart, so they say ….should have sex more frequently?????

    guess they can’t be talking to us Dominican….we are all smart..and LOVE SEX we are way ahead of them……

    Let us be human……..that’s what we are….

    Well pa pa, if that is true God save our nation. Many husbands leave their wives and are running woman out there, having sex and more sex and at the end they turning paro. You all not seeing them? The wives looking so nice and they like misery and people still feeling sorry for them. Something is wrong somewhere. The marriage bed is undefiled. Sin is a reproach to a nation. Adulterers will not see the Kingdom of God. Please people, do not let scientist destroy you. Everything can be found in Gods word. These are the days like the days of Noah. This is from the devil

      i’m sorry, but i missed the part in the article where they tell kids to go have sex.
      i swear they used the word adult more than once in it. the ppl that saying no sex before marriage and christian christian, i know for a fact that is mostly them children that in church every Sunday and in Bible school that more sneaking around having sex, or they behind the church with guys smoking or kissing, even having sex behind the church. i know of enough girls that christian, their fathers are pastors and they got pregnant while going to school or they wyla. had a cousin went to church every sunday even on the week day and she was sneaking around behind her mother back with a boy when she was 15. no mater what u can’t stop teens from having sex, they have to make the choice to not do it.

      Maybe I am missing something because I just can’t find what you are talking about anywhere in the news item. Nowhere did it suggest that our children should have sex to aid brain cell growth my friend.

        Congrats Freud for being so smart..yet I must say your brain is too small to comprehend the message.Instead you comment on the size of the letters.Is this your notion of using proper grammar?

    April 25, 2011

    God made sex, so it must be good. Itis at we do with it that can be bad.

    Having a nymphomaniac or a pervert for a partner can drive you insane.

    I hope young people dont think that they have found the secret to life in this article because sex, though it can be good where the person is mature and ready for it, where the person is immature and unready it can destroy their life literally and figuratively

      Brain growth does not equal intelligence..Think of it as a someone who does body building but can never fight because they didn’t learn how to use the muscles in combat. Whereas someone who only studies martial arts and has an average body will kick *&$
