but if homosexuality isn't caused by any genes, what causes it actually? If procreation is he main objective of any living thing, why is there an exception from this rule? Because gay people clearly cannot procreate (naturally)
What causes this unnatural variation in testosterone during pregnancy? There are many factors that could cause this. I'm not sure what, but I'm sure research has been conducted. Teratogens are everywhere (teratogens are substances or environmental agents which cause the development of abnormal cell masses during fetal growth). Could it be some sort of teratogen that alters the mothers hormonal level? Sure.
i do not believe that gay people exist for a purpose. I believe we all come out the same as babies. You do not know if your going to be gay when you get older. Its just the way some people are. They either want to be intrested in girls/guys or their same gender. Some homosexuals pick to be the way they are because the same gender know how to do it better & they understand their feeling and stuff & some gay people just have hatred towards the opposite gender.
Cool, so you're saying that people choose to be homosexual? I believe in this to an extent because being picked on as a young person and being called gay can really influence a teenager to re-evaluate his/her sexuality. However, the research I mentioned in my first post makes sense too.
