Does being exposed to confrontation/danger on a daily basis naturally increase testosterone levels?

Perhaps it's not the question you are really trying to ask, but the implication would be women and children who have lived with threatening partners or parents for large portions of their lives would then have extremely high levels of testosterone. Not sure that pans out.  

Testosterone isn't the stress hormone, cortisol is, and some studies indicated constantly elevated cortisol suppresses testosterone.  Probably more of a balance between the two and whichever has control will determine whether you fight or fly.
