Biological Sex and Sexual Orientation: Nature vs. Nuture

The topic is on Biological sex and sexual orientation: Nature or Nurture?
The paper should talk about how different factors (biological or social) can effect sexual orientation. Some questions to consider answering include:
Which hormones are implicated in sexual development and how are they implicated? Discuss cases of sexual development beyond the common dichotomous lens of male/female. What are the physical and behavioral outcomes of variations in biological sex? Is sexual orientation biologically determined or learned? What is the evidence?
We are required to address the neurobiological underpinnings.

I have attached a guideline with more information and included a couple of references to be used in the paper to defend the theory. Not all the references need to be used, only the ones that help provide information for the topic. There should be at least minimum of 10 references used though.
