Weird that you pull the one quote but ignore the rest of that paragraph which is about how being the leading cause of infertility is exactly the kind of thing evolution normally fixes.

"It’s odd for there to be such an easily-removable design flaw in the human body; evolution tends to remove them. Since it strikes at advanced ages, BPH doesn’t make a big impact on a man’s ability to pass on his genes. But being the leading cause of male infertility sure does. Their explanation is that evolution hasn’t had much time to work on the problem; in animals the spermatic vein is horizontal, and doesn’t have or need one-way valves. It’s our standing upright that yields the problem; in evolutionary terms that’s a recent development."

Not only is it recent in terms of human history; back to my point, it is only in the last few centuries that men in gneral have reached ages that expose the posture shift as a flaw.
