How long does it take for clomid to increase sperm count?

Elizabeth
My husband started taking clomid a month ago and I just started meds for our insemination next week. Is 6 weeks on clomid enough time to see his numbers improve? And what if it didn't even work? Or worse, made his numbers decrease? Anyone have advice on how else we can elevate his numbers for a successful <a href="https://glowing.com/glow-fertility-program">iui</a> if clomid failed? Our doc keeps suggesting that <a href="https://glowing.com/glow-fertility-program">ivf</a> gives us the best chance when low sperm count is the issue, but with all that it entails (and the money), I really want this <a href="https://glowing.com/glow-fertility-program">iui</a> to work. Any tips or advice welcome :)
