Jennifer Ouellette finds it throughout history:
In ancient China, most gemstones were said to be drops of divine semen that had hardened after fertilizing the earth. For instance, jade was believed to be the dried semen of celestial dragons. (Note to self: never wear jade again.) In Chi Kung and other forms of Chinese medicine, "jing" is sexual energy, which can also denote "essence" or "spirit.” That’s why masturbation isn’t advised among Chi Kung practitioners: it’s a form of energy suicide. … In ancient Rome, the orchid was believed to derive from the semen of copulating satyrs, just because its twin bulbs reminded the Romans of testicles.
