Nope estrogen and testosterone are in direct opposition so success is at best partial: limited moobs and partial fertility. Testicles make testosterone and testosterone gets in the way of breasts. IIRC there was a Russian athlete who went from a small chest (B cup maybe?) to F cups simply from retiring, as heavy exercise tends to come with elevated testosterone. Estrogen reduces LH and FSH which decrease testicle activity. In fact estrogen, prolactin and testosterone are the main ways LH and FSH production is down-regulated. Estrogen and prolactin in particular.

Here's a good writeup on how it all works:

Maca may increase DHEA a little which may increase other hormones in the testicles (or ovaries in women), but only if you have functioning LH or FSH. So "Oh I'll use a major NBE herb and I'll just use some minor fertility herb to compensate" is a dangerous assumption that's bound to fail. The proper way to go about it would be 2,000 mg 100:1 tongkat ali extract to block estrogen and prolactin in the hypothalamus. Like PM this is a major herb, not some weak sauce. You may need less to start to avoid excessively sore rapidly enlarging testicles and a huge testosterone spike leading to sore upper legs. But then the high testosterone limits how much moobs can enlarge. It's not "add a bit of this then add a bit of that", there are a lot of negative limiting factors that determine sexual function as much or more than the positive factors.

I once found a study suggesting 500 mg PM could be reversible, but maybe not 1,000 mg PM within the limited timespan of the study. Most males tend to use 2,000 mg PM. You'll have to search the forums for precisely how well reverting worked for others. But IIRC it's ok at first and then the deeper you go in the harder it gets to ever go back.

So it's like fire and water. You can find them together in special circumstances but it doesn't work well and it's not the norm.
