Anyway, our IRL infertile friends who see the good doctor in Omaha have the husband taking something called "maca" (root extract) - a Peruvian herb - which Dr. H is recommending to improve motility. That's not its "label" use, but apparently there has been some success with it.
So here's the good news: I went to our friendly local Vitamin Shoppe this evening (where I got my Fo Ti root and Guarena - thanks Cathy! They seem to be working, or something is working), and they had FOUR DIFFERENT BRANDS of Maca. So this stuff is definitely available. I would guess GNC and suchlike places have it too.
So there you have it: if the guys just wanna hang around poolside instead of doing their required laps, for $10 or $12, no prescription, you can get yourself 60-100 of some Peruvian magic pills that may, or may not, do anything about it.
(I am positive at least one blogger I read has struggled with motility issues that haven't responded to the treatments they've tried, so I hope this information gets where it needs to go!)
