The single best combo to help guys with low sperm count is an HCG + rFSH combo. Follistim, Bravelle and Gonal F are some of the names rFSH is prescribed as but it is very expensive which is why people always first try Clomid to see if they have any luck with that. You can directly stimulate sperm production with rFSH and it will work 9/10 times to get you to normal range, unless your sertoli cells do not function normally, but it can take time since sperm cells take over 2 months to mature. Ask your doc about it...
