In human development, certain genes act as master switches, ensuring that we are born with similar attributes (one head, two lungs, 10 fingers) in nearly all circumstances. Such genes tend to be highly reliable and resistant to environmental factors. Related
But the gene responsible for activating male development is surprisingly unstable, leaving the pathway to male sexuality fraught with inconsistency, a study finds.
The SRY gene on the Y chromosome sets off the growth of male sex organs in human embryos (all of which start out essentially female). To study the gene, researchers at Case Western Reserve University looked at families in which daughters inherited a Y chromosome, a rare occurrence in which SRY fails to fire, leaving a genetically male embryo to develop as a sterile female.
They found that SRY is highly vulnerable to environmental factors, allowing the slightest interruption to significantly alter male sexual development. That leads to a wide divergence of testosterone-related male attributes (among them muscle mass, aggression and genitalia development) from one man to another, according to the study, which was published in The Proceedings of the National Academy of Sciences.

Y-ping? that’s Y.
SorRY the president is a pansy, his SRY was broken.
Que es mas macho?
So how far will the homos and their supporters have to stretch this to “prove” homos are “born that way”?
When I was going thru puberty, my jeans were very sensitive to certain environmental factors...........
The next step is to develop a ‘cure’............
LOL! Ya got me...
The question is. How far will they go to deny their mother’s habits during pregnancy may have selected them from the genepool. They have been voted off the evolutionary island.
It’s not, in fact, genetic. It’s environmental.
The question isn’t ‘born that way’ so much as ‘made that way in the womb’.
In much the same way that DES babies are ‘made that way in the womb’ and thalidomide babies are ‘made that way in the womb’.
Well, prenatal testing becoming the cassus belli against fetuses, I’m sure someone will develop a test to determine what the state of a particular infants SRY gene is in and use that result to determine whether to continue the pregnancy...or not.
I just wonder.
We know that exposure to certain microbes (and the resultant development of troublesome antibodies) during pregnancy can be a bad bad thing...
What if exposure to some common virus or microbe at a particularly sensitive developmental stage can do this...
Like influenza exposure in 2nd trimester and later development of schizo.
I believe this is a combination factor of birth defects, as described, and social and criminal factors when growing up.
NYT = junk science
The Times reported this...it was a study in a scientific journal. The Times is dreadful, but this is straight reporting of a study. It is not junk science. Your comment was a junk comment, though.
