The sperms are cells, they have a specific structure, that consists of a head a neck and a long tail... but I think you mean what are the materials of semen.
Well, including the sperms, the other materials of semen are... fructose, prostaglandins,some lipids,few enzymes, and a little citric acid, a significant number of bicarbonate ions(hence alkaline ph), also, some amount of mucus.
What substances increase spermatogenesis, well, I don't know of any specific substance, (though certain medicines do exist), I suggest you consult a sexologist, for that question.
