"Seminal plasma of humans contains a complex range of organic and inorganic constituents. They include metal and salt ions, sugars, lipids, steroid hormones, enzymes, prostaglandin hormones, amino acids and basic amines."

And this is from another website regarding a portion of substances found in human semen:
â?¢ ascorbic acid (vitamin C, for tissue maintenance)
â?¢ blood-group antigens (from immune system)
â?¢ calcium (mineral)
â?¢ chlorine (oxidizing agent)
â?¢ cholesterol (steroid alcohol present in body fluids)
â?¢ choline (base, part of the vitamin B complex)
â?¢ citric acid (occurs during cellular metabolism)
â?¢ creatine (nitrogenous substance found in muscle)
â?¢ deoxyribonucleic acid (DNA)
â?¢ fructose (sugar used for energy)
â?¢ glutathione (peptide amino acid)
â?¢ hyaluronidase (enzyme)
â?¢ inositol (sugar found in muscles)
â?¢ lactic acid (byproduct of muscle use)
â?¢ magnesium (mineral)
â?¢ nitrogen (gas found in all living tissue)
â?¢ phosporus (mineral)
â?¢ potassium (mineral)
â?¢ purine (compound of uric acid)
â?¢ pyrimidine (organic base)
â?¢ pyruvic acid (formed from either glucose or glycogen)
â?¢ sodium (salt)
â?¢ sorbitol (body alcohol)
â?¢ spermidine (catalytic enzyme)
â?¢ spermine (ammonia compound found in sperm)
â?¢ urea (from urine)
â?¢ uric acid (from urine)
â?¢ vitamin B12 (for proper function of nervous system and metabolism)
â?¢ zinc (mineral)

So, it does have proteins (and if they aren't proteins, they are beneficial things)
