This was an interesting paper
I have heard of men on androgen ablation as primary therapy using estrogen patches to alleviate symptoms of androgen ablation, but not as a concurrent therapy with a therapeutic dose. I have heard of men using patches (or DES) as their primary therapy, but not in conjunction with androgen ablation.
Has anyone heard of concurrent use?
It makes sense in that combining other therapies seems to provide an enhanced effect. I would be surprised if this hasn't been tried before?
