I quickly purchased 230 dollars worth of bitcoin since I was aware of the transaction fee I was going to incur would leave me with 219 dollars worth of bitcoin to spend, enough for four NKNW tubes in my mind. What I didn't realize is that there was another 10 dollar fee coinmama was charging me to purchase and transfer my coinbit currency to my wallet. Nevertheless, I paid it and continued on. There was a notice on coinmamas website that claimed the transfer could take as long as 48 hours, however, my experience was far less than 48 hours, it only took 3. After my wallet was filled with a fraction of a bitcoin, yes my 219 dollars was worth a fraction of 1 bitcoin.
The second theory is similar and is known as "evolutionary neuroandrogenic (ENA) theory of male aggression".   Testosterone and other androgens have evolved to masculinize a brain in order to be competitive even to the point of risking harm to the person and others. By doing so, individuals with masculinized brains as a result of pre-natal and adult life testosterone and androgens enhance their resource acquiring abilities in order to survive, attract and copulate with mates as much as possible.  The masculinization of the brain is not just mediated by testosterone levels at the adult stage, but also testosterone exposure in the womb as a fetus. Higher pre-natal testosterone indicated by a low digit ratio as well as adult testosterone levels increased risk of fouls or aggression among male players in a soccer game.  Studies have also found higher pre-natal testosterone or lower digit ratio to be correlated with higher aggression in males.     
Erectile dysfunction is not uncommon after radical prostatectomy and men who undergo ADT in addition to this are likely to show further decline in their ability to engage in penetrative intercourse, as well as their desire to do so.  A study looking at the differences of using GnRH-A (and androgen suppressant) or an orchiectomy report differences in sexual interest, the experience of erections, and the prevalence of participating in sexual activity. Men reporting no sexual interest increased from % to % after orchiectomy, and from % to % after GnRH-A; men who experienced no erections increased from % to %; and men who did not report engaging in sexual activity increased from % to % after orchiectomy and % to %.  This study suggests that the GnRH-A and orchiectomy had similar effects on sexual functioning. A vicious cycle whereby lowering testosterone levels leads to decreased sexual activity, which in turn cause both free and total testosterone levels to decline even further.  This demonstrates the importance of androgens for maintaining sexual structures and functions.
