Research Abstract	Characteristic analyses of seminal gel in ejaculated boar semen were analysed. The gel could be dissolved in both conditions of severe acidic and alkaline conditions, whereas it is stable around neutral conditions. Chemotaxis of polymorphonuclear leukocytes for seminal gel was not observed. Preparation of sperm capsule by mixing frozen-dried seminal gel with boar semen or washed sperm allowed survival and release of sperm from the capsule. Chemical analyses of seminal gel demonstrated that the gel is o-glycan-rich. Analyses of sugar chains and peptides showed that seminal gel contains specific sugar chains and protein. These information may have possibilities to contribute in wide fields including biomedical area.
