The Science Of Sex 4

Many people talk about saving themselves for marriage, which I think is a great thing.  Whereas traditionally, sex has always been thought of as something that feels good, researchers are shedding light on some of the more positive aspects of sex (albeit with less than substantial evidence).  What do you think of these particular findings?  Do you agree or disagree, or has this given you some “aha” moments?

  1. For a country where you can purchase porn and used schoolgirl underwear from vending machines, Japan is no stranger to sexual promiscuity.  However, recent survey by Japan’s health ministry found that one-third of all marriages in Japan are sexless (have not had sex with their spouse for over one year).  A survey by the University of Chicago in 2006 found that Japanese respondents were the least sexually satisfied of people from 29 countries, which echoed another survey conducted by condom manufacturer Durex in 2005 that on average, Japanese have intercourse 45 times a year, compared to the international average of 103 times.  The possible reasons include having sex only to conceive, men are getting sexually please outside the home, awkwardness of having sex when their children and their parents are one door down, and because Japanese men are too stressed out from work.  What would be interesting is whether these same women were sexually active prior to marriage.
  2. Last week’s edition talked about some negative aspects to certain forms of intimacy.  This week, we will talk about some of the positives.  One of the most credible studies done by Queens University in Belfast tracked the mortality of approximately 1,000 middle-aged men over the course of a decade.  In the findings published in 1997’s British Medical Journal, it reported that men with the highest frequency of orgasms enjoyed a death rate half that of those who have a lesser frequency of orgasms.  In the follow-up to the study in 2001, it was revealed that men who had sex three or more times a week reduced their risk of heart attack or stroke by half. It’s interesting that these research studies were conducted on men only.  Is it because they do more work in the sack, or is it because only few women experience orgasms?  In any event, I would appreciate some research for women, please.
  3. Who needs flu shots when you can just have sex?  Wilkes University in Pennsylvania conducted a research that reported having sex once or twice a week show 30% higher levels of an antibody called immunoglobulin A, which is the first line of defense against colds and flu.  It binds to bacteria that invade the body, and activates the immune system to destroy it.  Interestingly enough, those who have sex three times or more have a reverse effect, lowering the level of immunoglobulin A.  The reason for this reverse effect is unclear.
