Abstract

Sexual differentiation is the early life process by which the brain is prepared for male or female typical behaviors, and is directed by sex chromosomes, hormones and early life experiences. We have recently found that innate immune cells residing in the brain, including microglia and mast cells, are more numerous in the male than female rat brain. Neuroimmune cells are also key participants in the sexual differentiation process, specifically organizing the synaptic development of the preoptic area and leading to male-typical sexualbehavior in adulthood. Mast cells are known for their roles in allergic responses, thus in this study we sought to determine if exposure to an allergic response of the pregnant female in utero would alter the sexual differentiation of the preoptic area of offspring and resulting sociosexual behavior in later life. Pregnant rats were sensitized to ovalbumin (OVA), bred, and challenged intranasally with OVA on gestational day 15, which produced robust allergic inflammation, as measured by elevated immunoglobulin E. Offspring of these challenged mother rats were assessed relative to control rats in the early neonatal period for mast cell and microglia activation within their brains, downstream dendritic spine patterning on POA neurons, or grown to adulthood to assess behavior and dendritic spines. In utero exposure to allergic inflammation increased mast cell and microglia activation in the neonatal brain, and led to masculinization of dendritic spine density in the female POA. In adulthood, OVA-exposed females showed an increase in male-typical mounting behavior relative to control females. In contrast, OVA-exposed males showed evidence of dysmasculinization, including reduced microglia activation, reduced neonatal dendritic spine density, decreased male-typical copulatory behavior, and decreased olfactory preference for female-typical cues. Together these studies show that early life allergic events may contribute to natural variations in both male and female sexual behavior, potentially via underlying effects on brain-resident mast cells.

I would say yes, it’s likely. But sexual differentiation is not something to be concerned about.

If it was a similar study but with regards to expressing socio and psychopathic tendencies instead, then there would be need to be very concerned.

@nevim, please google the original poster. 

Like this kind of shite?

I think these people just exist for our amusement :D.

THEY are the freaks of nature!

 

And to think, while I was innocently trying to point out where -any-study-such-as-that should hold our concern, I was probably (clearly), unbeknownst to me, speaking about the actual OP ‘PERSON’ and ‘THEIR’ tendencies... lets absolutely NOT give any personal pronouns here :)

Homophobia, or any phobia towards a persons sexual orientation (not preference!!), is a lack of understanding and appreciation of what sexual orientation is.

Sexual orientation is never something that you, as an individual, choose. So when you find yourself attracted to someone, not standard or appropriate, you have to deal, not only with your own confusion, but with the intolerance of your peers.

The biggest misconception there is about alternative sexual attractions, is that it's a choice.

IT'S NOT A CHOICE! It never was!
