[This is a fascinating topic. I had never heard of anything like this before, and it shows you how far the fantastic science of DNA is moving. At first I was not sure if this was a serious topic. But I checked out the 2 sources and this is definite science. I’ll be putting the 2 scientific sources below so you can check them out.
The idea that women somehow can obtain DNA from other sources and store that DNA in their own brains is incredible. Nature is fascinating beyond belief!
This is the first time I’ve come across this idea before. I have heard of something almost similar, but I can’t remember the word for it, so I’ll describe it. I have heard that apparently Russian/Soviet scientists discovered that if a woman has sex with a man of another race, that somehow it actually affects her body in some way and her body retains some kind of “memory” of it. I just can’t think of the term I was told. Perhaps some of you can drop some comments. The moment I see the word I’ll recognise it.
This entire topic of whether women can acquire DNA from sources other than their parents is fascinating. The strong suggestion below is that the only possible workable mechanism is sex. From these science articles that does seem like the most likely conclusion. But you never know what other twists exist in this. This would be a most fascinating topic to follow up on.
One explanation which I can’t make sense of is this term “unrecognized spontaneous abortion”. How can an abortion be unrecognised? Would this apply to a time very early in a woman’s pregnancy? I did a bit of digging and found this:
I found this: The study confirmed what many scientists have long suspected: The female body discards a large percentage of its fetuses in the first month or so after conception. Source: MOST MISCARRIAGES GO UNRECOGNIZED, STUDY SAYS – https://www.washingtonpost.com/archive/politics/1988/07/28/most-miscarriages-go-unrecognized-study-says/d06d3b92-bb2d-4162-8bd2-3b4b3909368d/?noredirect=on&utm_term=.9cf91401e99d
So it seems from the above that “unrecognised spontaneous abortion” may be much more common than we realise. So that appears to me to indicate (if I understand this correctly), that a woman could get DNA from a fetus she had, which aborted (knowingly or unknowingly). In the article published below, the (non-scientific) writer assumes that sex is the most common possible source of the DNA. It does appear to me as if there is a possibility that the writer below is correct in his/her assumptions that sex could be the most likely source of this DNA. Anyhow, the topic is fascinating and I look forward to getting more information/updates on this in the future. I’m very fascinated by DNA and how it works.
Here are the 2 scientific sources they got this information from:
o Male microchimerism in women without sons: quantitative assessment and correlation with pregnancy history (2005) – https://www.ncbi.nlm.nih.gov/m/pubmed/16084184/
o Male Microchimerism in the Human Female Brain (2012) – http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0045592
In the science article (above) from 2012 it says: “We report that 63% of the females (37 of 59) tested harbored male microchimerism in the brain. Male microchimerism was present in multiple brain regions. … In conclusion, male microchimerism is frequent and widely distributed in the human female brain.”
That is very fascinating. This seems to be quite common. But does this mean that every time a woman has unprotected sex that some of the male’s DNA can go into her brain? Perhaps not.
The first article above is from 2005. So I would think that by now there must be much more new information on this topic.
NB: A friend of mine told me that scientists often know things that can be quite shocking, and they keep it to themselves if they believe it could cause problems. He told me that he’d come across a reference that as far back as the 1940s, that scientists knew that 20% of the children of married women were fathered by a man the woman was NOT married to at the time. He said that the scientists kept this hushed up until the 1980s.
So I do wonder what information scientists have that would be of tremendous use to us? I suspect that with DNA and IQ and stuff like that, that scientists will be able to do all kinds of strange things that are almost beyond science fiction. Jan]
Women retain and carry living DNA from every man with whom they’ve made love with
Women retain and carry living DNA from every man with whom they have sexual intercourse, according to a new study by the University of Seattle and the Fred Hutchinson Cancer Research Center.
The study, which discovered the startling information by accident, was originally trying to determine if women who have been pregnant with a son might be more predisposed to certain neurological diseases that occur more frequently in males.
But as the scientists picked apart the female brain, the study began to veer wildly off course. As it turns out, the female brain is even more mysterious than we previously thought.
The study found that female brains often harbor “male microchimerism“, or in other words, the presence of male DNA that originated from another individual, and are genetically distinct from the cells that make up the rest of the woman.
According to the study: “63% of the females (37 of 59) tested harbored male microchimerism in the brain. Male microchimerism was present in multiple brain regions.”
So 63% of women carry male DNA cells that live in their brains. Obviously the researchers wanted to know where the male DNA came from.
Anyone care to guess? From the women’s fathers? No. Your father’s DNA combines with your mother’s to create your unique DNA. So where else could it come from?
Through the study the researchers assumed that the most likely answer was that all male DNA found living in the female brain came from a male pregnancy. That was the safe, politically correct assumption. But these researchers were living in denial.
Because when they autopsied the brains of women who had never even been pregnant, let alone with a male child, they STILL found male DNA cells prevalent in the female brain.
At this point the scientists didn’t know what the hell was going on. Confused, they did their best to hide the evidence until they could understand and explain it. They buried it in numerous sub studies and articles, but if you sift through them all you will find the damning statement, the one line that gives the game away and explains exactly where these male DNA cells come from.
“CONCLUSIONS: Male microchimerism was not infrequent in women without sons. Besides known pregnancies, other possible sources of male microchimerism include unrecognized spontaneous abortion, vanished male twin, an older brother transferred by the maternal circulation, or SEXUAL INTERCOURSE. Male microchimerism was significantly more frequent and levels were higher in women with induced abortion than in women with other pregnancy histories. Further studies are needed to determine specific origins of male microchimerism in women.“
So according to the scientists, the possible sources of the male DNA cells living in the women’s brains are:
- an abortion the woman didn’t know about
- a male twin that vanished
- an older brother transferred by the maternal circulation
- sexual intercourse
Considering the fact that 63% of women have male DNA cells residing in the recesses of their brain, which of the above possibilities do you think is the most likely origin of the male DNA?
The first three options apply to a very small percentage of women. They couldn’t possibly account for the 63% figure. The fourth option? It’s rather more common.
The answer is 4. Sex.
This has very important ramifications for women. Every male you absorb spermatazoa from becomes a living part of you for life. The women autopsied in this study were elderly. Some had been carrying the living male DNA inside them for well over 50 years.
Sperm is alive. It is living cells. When it is injected into you it swims and swims until it crashes headlong into a wall, and then it attaches and burrows into your flesh. If it’s in your mouth it swims and climbs into your nasal passages, inner ear, and behind your eyes. Then it digs in. It enters your blood stream and collects in your brain and spine.
Like something out of a scifi movie, it becomes a part of you and you can’t get rid of it.
We are only now beginning to understand the full power and ramifications of sexual intercourse.
