i dont think it will make anything worse males can use bovine ovary too to grow breasts.

But males don't have a system in place that shuts off the body's own production of female hormones and down regulates everything in response to too having too high levels.

So if a male adds estrogen - bam - he grows boobs. If I add estrogen my body goes hey we got too much estrogen in here! slow down production so that we can maintain balance and avoid problems (like cancer).

It's not that simple.
