I have a bridge you would be interested in buying. It's pretty. And cheap
Give the gall a break ... the idea of a virgin birth worked wonders for one major world religion.
Now, about that bridge ...
Meanwhile, I'm not sure that there is neurophysiological evidence for very much at all. Brain science is still developing.
WE have one article, for example, by a duo, one of whom is the aptly named 'Dick Swaab' that claims that even paedophilia is determined in-utero.

Another 2015 chapter, by a Randi Ettner, concludes that,
"The etiology of gender identity, typical and atypical, presently remains unknown. However, the mounting evidence for a biological basis is compelling. No doubt the next decade will bring new data that elucidates the complexities of identity formation and amplifies understanding of the transsexual phenomenon".
A 2017 paper by Bramble et al notes that
"Evidence provided from the rodent model has laid the groundwork for our understanding of how in utero hormonal milieu and chromosomal composition influence brain development and contribute to generating observed sex differences. Unfortunately, similar research in humans in adequate depth is lacking from a biological standpoint. Investigating sex differences in human brain structure and cognitive development is challenging because humans are a socially influenced species, making it difficult to tease apart the effects of environmental influences from biological contributions."
In other words - there is little evidence and the jury is out.
