Reishi seems to have inhibiting effect on 5-alpha-reductase (study):
Red reishi, commonly known as LingZhi in Chinese, is a mushroom thought to have many health benefits. In a research study exploring the anti-androgenic effects of 20 species of mushrooms, reishi mushrooms had the strongest action in inhibiting testosterone (3). That study found that reishi mushrooms significantly reduced levels of 5-alpha reductase, preventing conversion of testosterone into the more potent DHT. High levels of DHT are a risk factor for conditions such as benign prostatatic hypertrophy (BPH), acne, and baldness.
So, reishi is a multitalent.

In-vitro 5ar inhibition is different from in-vivo 5ar inhibition. Most “natural” supplements that inhibit 5ar in-vitro do not work in-vivo.
Some older study: Anti-androgenic activities of Ganoderma lucidum (Reishi)
In this paper, we have demonstrated the in vitro and in vivo anti-androgenic activity of Ganoderma lucidum for the first time.
@Virilius, thank you for your point. Will notice it for future analysis.
