Hormones and Genes Control the Loyalty Degree of Love
6/28/2013 12:51:32 PM
Yerkes National Primate Research Center of Emory University, Larry young in the prairie vole's brain research found that hormones and genes control the loyalty degree of love.
Young said that only 5% of mammal lifelong monogamy, prairie voles are among them.
Found that women’s hormone decided to partner loyalty is oxytocin, human female and female prairie voles would secrete the hormones before and after childbirth. Scientists inhibit the oxytocin receptor, female prairie voles began to "find new love". For men, the same role is vasopressin.
In addition, the scientists found that a few "flower heart" prairie vole they carry a gene variant, the same situation also occurred in the human male.
The Swedish biologist Hasse·Walum said, the men carry the gene variant whose love loyalty is relatively low, have more marital problems. He thought that the small difference is remarkable.
According to the study report in the Proceedings of the National Academy of Sciences of the United States, a gene influenced brain activity may prompt men no marriage, derailed in marriage, and even divorce. Men having this gene are harder to give commitment, even if marriage, they are easy to make his wife feeling unfortunate.
These flower heart men, what kind of external characteristics do they have? How should we identify such men? Let's take a look at it:
A Swedish Karolinska Institute biologist Hasse· Walum studied 552 pairs of twins, trying to learn more about the regulation of related gene which a body to the brain vasopressin (antidiuretic hormone) . The answer is obvious, in the men carrying two of this gene variant, about a third had occurred severe emotional crisis in the past 1 years, the number were twice than men without the gene mutation.
There was a team test blood samples from these men, carefully analysis gene "vasopressin receptor 1 a". The gene affects the hypothalamus produces hormones vasopressin receptor. A study found that the gene variant type 334 alleles are associated with male of establishing close relationships with a partner.
The truth is, there are two copies of the allele man compared with no or only one man, whose marriage crisis chance were twice as last year. There is one or two copies of the allele of men compared with the men without it, the former wives’ marital satisfaction were lower. Without this allele men, 20% of marriage crisis, there are two copies of the allele man of 34% year-on-year. At least having one copy of this allele, the men of 30% unmarried, 17% year-on-year without the gene.
Of course, there are plenty of possibilities which lead to a person feeling problems, as there are numerous factors to force your adult height, it is more than just genes. But can not be ignored is the fact that, if your parents are tall, you are born with such a gene, then you will be more easily than parents very short men yo grow taller.
Maybe someone will ask: even if he carries two gene variants, how can we know? Yes, we can't change. But now we can know is that: the more he carries the gene variant, the less he vasopressin secretion.
What usefulness is vasopressin? Vasopressin, it also called antidiuretic hormone, is one of neurological pituitary hormone. It made mammals blood pressure elevatory through capillaries and arterioles contraction. And promote kidney water reabsorption (mammals) and absorbing moisture from skin and bladder membrane (amphibians). Vasopressin may regulate water inflow of cell. Vasopressin can also stimulate the capillaries, make it shrink. As the name shown, “vaso” is the meaning of "blood vessels", “pressin” is the meaning of "pressure", vasopressin produced in the pituitary, secreted into the circulation system. At the same time used in the treatment one of cardiac nerve pituitary hormones. Antidiuretic effects are mediated by cyclic AMP change the permeability of membrane, but the details have not been understood yet, and show a little activity of oxytocin. Vasopressin and oxytocin, were all extracted by V.du Vigneaud etc, refined, structure comfirm and chemical synthesis in 1953. With a circular section of the peptides are consisted of nine amino acid residues.
Now, look at this sentence: "It made mammals blood pressure elevatory through capillaries and arterioles contraction."
On the one hand, it causes the vasoconstriction of mammals, blood pressure elevatory, have anti-diuretic effect, promote water reabsorption of the kidney. On the other hand, it inhibits flower heart.
So someone did such a study, content was only word: “tell me your pee times.” The investigation aimed at two kinds of people. One was the men changed one sexual partner in the past three years or not changed, hereinafter referred to as the devoted man; Another kind of men who changed five more sexual partners in the past three years, hereinafter referred to as flower heart man. The result of the survey was shocking! Urine more than 10 times every day in flower heart male was forty percent of the flower heart group! This shows the physical phenomena and flower heart of the strong positive correlation.
Look at the chart in this horror, you know, in terms of probability, you'd better avoid the men who urinate often extremely. Have a saying in our ancestor that flower heart male is kidney failure because of making more women always run toilet. But, in fact, their internal vasopressin namely antidiuretic hormone is an acute lack of which makes them who have to always run toilet. However, the view of ancestor is the same with the answer of scientific research.
It is important to note that forty percent of the flower heart male show such symptoms, is not to say that flower heart male recognition rate is only 40%. In fact, when we put the spotlight on urination times in more than 10 times compared with two columns and then we can know the ratio of men that showed the sign. We can find that, one hundred male pee times in more than 10 times every day, about 90 people are flower heart males, 10 are exclusively males. That is to say, urinate more than 10 times a day, the possibility of the men changed five partners in three years up to 90%. Temporarily is not especially obvious gap compared urinating in different times.
In view of the role of vasopressin, and an untested ideas likewise, high blood pressure male is not flower heart, but with a lot of people for their own blood pressure is not very clear, I don't research into the problem again.
However, the findings cannot be applied to all individuals, but at the beginning of the relationship, you can look at the frequency of his urine. If you date, he always went to the bathroom frequently, so you should remain on high alert.

LOL, this an interesting study.. But it is not valid in the case of judging individuals... Because anngiven man might on a medication thqt increass or decreses his urine flow.. Or he might be dehydrated because he is sweating profusely all the time in hot steamy Southern China, he might have a condition like diabetes wherein his kidneys are clearing out extra sugar or whatever else decreses your trips the water closet... Without going through the long list of environmental or othe health factors to rule everything else out, you just cant know if this poor guys frequent. Athroom trips are because hes inherently a flower heat or not. Statistics are valid when looking at sizable populations... Never forget that your guy, who has fallen in love woth you and wants to be with you always has the chance of being that one in 10 who isnt.. And if you are. Counting him out by counting his pee frequency, lol, you are doing both of you a huge diservice.
Environmental factors can break OR make the relationship just as quickly.. If your guy is a frequent peer/flower heart maybe it just means you need to spend a little extra effort to see that hes happy and content with you.. As corolation must never be confused with causation.. Maybe these guys with more lovers over a 3 year period are more sensitive to some other factor. Possibly they need more sex or more of some other behavioral stimulant..
Personally i can see a bunch of chinese women all with little clickers in their pockets now trying to count the times we go to the bathroom, instead of focusing on the conversatuon or being into the moment. That can certainly harm a dates outcome.
What if the hotpot from last night is just causing him to make more tripa the bathroom than normal but its for a wholy different purpose than you were thinking? This poor guy could be in real gastrointestinal stress and your labeling him a cheater, whenyou should be finding him some stomach medicine.
The actual outcome of this study is going to be a mass marketed, to women, powdered and ingestible form of vassopressin... Women in droves will begin buying it by the kilo and start sprinkling it into their mens food, drinks, blowing into their noses when they sleep.. Sprinkling onto their girlie parts before sex... And soon we will have a mystrerious epidemic of hypertension among foreign males with Chinese wives and girl friends, numerous heart attacks will follow... And nobody will understand what is the cause.. But once the statistics are analyzed it will undoubtably point to "patients were ten times more likely to be in a relationship with a Chinese partner so therefore Chinese women cause high bloodpressure and should be avoided at all costs!!!
Yes studies like this are interesting but reading into them to deeply only leads to eugenics and dna profiling or crazy behavior like judging men based on secret pee counting.
... Sorry i was going to write more but I have to run to the WC...

What about men who sometimes pee a lot, and sometimes don't? I find if I drink a lot, I pee a lot, all other things being equal.

The samples are less than 100 people. You know, let the flower heart male themselves turnout that is not too easy. Sample capacity is not enough , the conclusion is not rigorous, put it on the blog, for have a learning reference.

Last blog all men were frisky chimpanzees...this blog they are vole rats urine! Next it will be slugs and snails and puppy-dog tails!
By the way...you shouldn´t be too harsh on vasodilators - Viagra is one!
Maybe the reason your partner is heading to the bathroom is to pop one of these little blue pills! And maybe that isn´t such a bad thing!!!

A man who hasn´t changed partners in the last 3 years may not be devoted...just lazy! Or have some conviction to stay together for the children, for social status, not to upset their parents,etc.
Is a man who shows no affection to their partner a ´devoted man´?

@TimG yes Tim, i guess thats true for me too... Hmmm come to think of it I bet if we did a study wed find that WOMEN who drink a lot ( and therefore likely pee a lot as well ) are more promiscuous and likely to have more partners in a given time period too.
Maybe we should all start counting womens trips to the bathrooms to know who to go speak to when they announce last call... Because, you know, with all that peeing she might need a gentleman to give her a lift home.
