/u/MisterYouAreSoDumb, what do you think about this claim: "The crude extract from the root of Polygala Tenuifolia Willd could immobilize and kill 100% spermatozoa within 20 s in vitro". I'm skeptical to use your Polygala 20:1 now.

In Vitro
So it kills sperm in a test tube when exposed directly to them. Being exposed to the air kills sperm, but you still breath, right? Your sperm are not going to be directly exposed to crude extracts of polygala unless you inject it directly into your scrotum. There is NO evidence that polygala affects sperm in any way IN VIVO. That's all that matters. It has zero bearing on oral usage of polygala.
