The article you quoted (which I have read) says nothing whatsoever about there being any connection of the brain to the testes. It says that they have similar proteins; it then says that this may be because there are some similarities in how they function; it then proceeds to say this is analogous to convergent evolution – giving the example of koalas and humans having similar fingerprints despite having had no genetic connection for 70 million years.
So no, that article does not in any way whatsoever back your wild guess that the similarity of the proteins means that the brain and testes are communicating with each other. If anything, it contradicts that guess.
If I can’t find a credible source for this I will concede. It might be a matter of how you interpret communicate. Both the brain and the testes send out chemicals that both will be exposed to. And they both respond to these chemicals so there would be a feedback loop, and if there is magic this is where it would happen.
Are you aware that every single organ in the body sends out chemicals that every other organ will be exposed to? I mean, okay, the teeth may not send out signals. But the bones, skin, heart, and other muscles do, and that’s pretty much the main point of most glands.
Eyes are also rather isolated from the rest of the body.
If you wanted to say, “hey, i noticed a bunch of interesting similarities between the brain and the testes”, you might have gotten a more welcoming reaction.
Indeed, the lens of the eye is encased in a shell to keep the lens proteins isolated. If the lens capsule tears, there’s an immediate inflammatory response.
The same thing happens with hair! The hair follicle isolates the hair protein. If the follicle bursts, the body reacts as if the hair is foreign material.
When I was about 19 styling our hair with hairdryers was the thing. One time I burned my scalp pretty bad and my hair started falling out. Within about a year it settled in to where it pretty much stayed for the next 30 years or so. It would grow about 1" then fall out. I wonder if my follicles were exploding?
Now that the “one box” often shows enough of a link to make it obvious why the link has been posted, we have softened our stance on posting “just a link”. But you are stretching it too far. You’ve posted a raw link, with no discussion, at least three times in this thread, and in every case, there isn’t enough information in your post for a reader to understand why you posted it, and what relevance it has to the thread.
Going forward, please indicate why you are posting a link, and give the other posters an idea of what they contain. For instance,
I think XYZ. This link
[link here]
say a and b and c, which support XYZ.
Or
I came upon this link
[link here]
and it says (three sentence summary of link) which I thought was really interesting. What do you think?
The evidence supports the occurrence of environmentally-induced paternal epigenetic inheritance that shapes the offspring phenotype in the absence of direct or indirect paternal care and clearly demonstrates that sperm epigenetics is one of the major actors mediating these paternal effects. However, in most animals, while sperm makes up only a small portion of the seminal fluid, males also have a complex mixture of proteins, peptides, different types of small noncoding RNAs, and cell-free DNA fragments in their ejaculate. These seminal fluid contents (Sfcs) are in close contact with the reproductive cells, tissues, organs, and other molecules of both males and females during reproduction. Moreover, their production and use are adjusted in response to environmental conditions, making them potential markers of environmentally- and developmentally-induced paternal effects on the next generation(s). Although there is some intriguing evidence for Sfc-mediated paternal effects, the underlying molecular mechanisms remain poorly defined. In this review, the current evidence regarding the links between seminal fluid and environmental paternal effects and the potential pathways and mechanisms that seminal fluid may follow in mediating paternal epigenetic inheritance are discussed.
Uh… Just blindly quoting an abstract really doesn’t cut it, either. You need to say why you are posting the thing, and what you think it means.
Here, I’m guessing you are taking this as evidence of your hypothesis that… I’m not sure what your hypothesis is, actually.
But i read that abstract to suggest that, for example, is the male is stressed and his ejaculate contains unusual amounts of stress hormones, that might influence the epigenetics of the resulting zygote. I’ve read some articles about the effects of famine on epigenetics, for example.
