So exogenous T can actually help those things? Im getting mixed messages because peak on your site, as a con of T you have listed decreased oxytocin. Am I reading that right?
Well, I'm sure it's much more complex than this, but if you listen to the Paul Zaks video above - I'm not a video guy but this was well worth it imo - he states that
1. Oxytocin helps us bond and allows us to feel empathy for one another and is key hormone holding the social fabric together.
2. As testosterone goes up, oxytocin goes down.
3. High testosterone men for this reason tend to be less empathetic and more willing to punish others.
So the decreased oxytocin could happen from a man who went to pretty high testosterone levels in his HRT. As far as I know, no one has formally studied that though, so it's all theorectical at this point.
Now a low testosterone man has so many brain issues per my link above that worrying about oxytocin is really beside the point. A guy with classic low testosterone symptoms will be suffering from a variety of the following: fatigue, mental fog, decreased forms of memory, decreased visual/spatial, anxiety, depression, etc. It's hard for him to be empathetic cuzz he's so dang miserable!
