I posted the following somewhere, but i don’t think it was in this thread. please forgive me if I did.
A recent study done in the UK appears to establish some interesting things about pheremones; barely perceptible or even imperceptible chemical signals people emit and to which members of the opposite sex are receptive. Among the findings were:
-Ovulating women are more attractive to men than non-ovulating women. But the attraction is mutually selective. Ovulating women prefer, during that time, men who are more different from themselves in physiognomy. Both tend, at such times, to choose members of the opposite sex whose DNA and immune systems are complementary, not terribly similar.
-The respective pheremones of men and women normally lead to immune system complementariness in their choices of mates; that is, genetic differences that, acting in concert, bolster the immune systems in their children and minimize the chances of genetic defects.
-Contraceptives alter the normal pheremone signals, so that women on contraceptives are attracted to men to whom they would not be attracted if they were not on contraceptives, and whose DNA and immune systems are close to their own, with the same strengths and defects.
-The same is true of men. Their pheremone perceptions are “off” with women using contraceptives, and they are attracted to women who they would not be attracted to if they were not taking contraceptives, and who have immune systems and DNA much like their own.
-As a result, women on contraceptives have an enhanced likelihood of choosing “Mr. Wrong” instead of Mr. Right. Men have an enhanced likelihood of choosing “Ms Wrong”, and the chances of their children having immunological disorders or birth defects is increased if they conceive a child. Their chances of later disillusionment with their chosen mates is greatly increased.
-After sufficient time using contraceptives, even after women stop taking them, their systems do not ordinarily “reset” to normal.
So, does this affect the 40% rate?** Is it possible that the sexes make a lot of mistakes in their relationships and attractions because of contraceptives; mistakes that lead to less marriage, more divorce, possibly more abortions and, simply, bad choices in mating and family formation all the way around?**It seems possible. It also seems possible that some of the maladies that seem to be on the rise (like asthma, for instance, which is an immune disorder) are caused by contraceptive use; not directly, but by people choosing mates with the same immune system defects, thus enhancing them in their children. Oh, and another UK study strongly supports the proposition that the autism rate among people with highly similar DNA is much higher than among the population at large.
