Coffee: Grounds for Debate, a title in the Philosophy for Everyone series, argues that coffee is a performance-enhancing drug for thinkers. “The appropriate analogy is that coffee and philosophy go together like foreplay and sex,” insist editors Scott F Parker and Michael W Austin. “You can have one without the other, but the latter is better with the former and the former often leads to the latter.” Philosopher Basam Romaya says: “With the use of coffee, critical thinking abilities are sharpened, attention to detail enhanced.” This is a venerable claim: in the 16th century, Sheik Abd-al-Kadir, an Arab scholar, said: “No one can understand the truth until he drinks of coffee’s frothy goodness.” […]

So what about impotence? That does seem to have been overstated. The Women’s Petition Against Coffee prompted a broadside from men who argued that it “makes the erection more Vigorous, the Ejaculation more full, adds spiritualescency to the Sperme”.

That said, some say coffee may harm the sperm while speeding it on its way, which makes a kind of sense.
