Apocrine glands also produce cytokine,<ref>Ahmed AA, Nordlind K, Schultzberd M, Liden S. Immunohisto chemical localization of IL-1 alpha-, IL-1 beta-, IL-6- and TNF-alpha-like immunoreactivities in human apocrine glands Arch</ref>which is a very important nonantibody protein that generates immune response when in contact with specific agents.Plasma cells which increase in number in response to pathogens levels, secrete immunoglobulin.<ref>Flower PJ, Ladds PW, Thomas AD, Watson DL.

It is also very important to note that [[Langerhans cells]] that are present in the foreskin produce ''Langerin'', a substance that has been proven to kill the HI-virus human immunodefiency viris (HIV) on contact.<ref> de Witte L, Nabatov A, Pion M, ''et al''. [http://www.cirp.org/news/healthday2007-03-05/ Langerin is a natural barrier to HIV-1 transmission by Langerhans cells]. ''Nat Med'' 2007 Mar;13(3):367-71.</ref>

In infancy, simple sugars in breast milk, like antibacterial oligosaccharides, are acquired from the mother's milk and excreted in urine. University studies have shown that these substances cling to the mucosal lining of the inner foreskin and protect against urinary tract infections,<ref>Hanson LA, Karlsson B, Jalil F, ''et al''. Antiviral and antibacterial factors in human milk. In: Hanson LA, ed. ''Biology of Human Milk''. New York Raven Press; 1988. pp. 141-57</ref> as well as infections in other parts of the body.<ref>Coppa GV, Gabrielli O, Giorgi P, Catassi C, Montanari MP, Veraldo PE, Nichols BL. Preliminary study of breast feeding and bacterial adhesion to uroepithelial cells. ''Lancet'' 1990 Mar 10;335(8689):569-71.</ref> Babies excrete in their urine about 300-500 milligrams of oligosaccharides each day. These compounds prevent virulent strains of ''Escherichia coli '' from adhering to the mucosal lining of the entire urinary tract, including the foreskin and glans. For these reasons breast-milk is highly efficacious at preventing UTI.<ref>Gothefors L, Olling S, Winberg J. Breastfeeding and biological properties of faecal ''E. coli '' strains. ''Acta Paediatr Scand'' 1975 Nov;54(6):807-12.</ref> Rigorous study's studies have repeatedly demonstrated that breast feeding protects against urinary tract infections.<ref>Mårild S. Breastfeeding and Urinary Tract Infections. ''Lancet'' 1990;336:942.</ref> <ref>Pisacane A, ''et al''. Breastfeeding and urinary tract infection. ''The Lancet'', July 7, 1990, p50 </ref> <ref>Pisacane A, Graziano L, Mazzarella G, ''et al''. Breast-feeding and urinary tract infection. ''J Pediatr'' 1992;120:87-89.</ref>Researchers have shown that premature foreskin retraction can expose the penis to hospital strains of Escherichia coli and can result in UTI.<ref>Winberg J ''et al''. The Prepuceprepuce: A Mistake mistake of Naturenature? ''Lancet'' 1989, pp.598-99.</ref> Hence the protective function of the foreskin is in the child's best interest , especially during chemically treated diaper wearing years where feces mixed with urine can not only contaminate the permanently exposed urinary meatus but also the amputation wound from the circumcision surgery itself.
