try using HCG (human chorionic gonadotropin). A hormone that mimics LH (luetinizing hormone) in the body. LH stimulates testosterone production by the testicles and also stimulates sperm and semen production. You can get it on the internet--but do not use for more than 4 weeks, then a "drug holiday". Also L-arginine and L-lysine, both are amino acids, as well as zinc.
