Definition / general
  • Although immunohistochemistry often detects lactoferrin (Ann Pathol 2004;24:236), amyloid apparently derives from semenogelin I, the major secretory product of the seminal vesicles (J Lab Clin Med 2005;145:187)
  • Semenogelin I and II are mainly responsible for immediate gel formation of freshly ejaculated semen, and are degraded by the proteolytic action of prostate specific antigen/PSA (J Androl 1996;17:17)
