Seminal plasma proteins prolong the viability of rainbow trout (Oncorynchus mykiss) spermatozoa.
Rainbow trout (Oncorhynchus mykiss) spermatozoa were incubated in artificial sperm motility inhibiting saline solution (SMIS), in SMIS containing seminal plasma proteins or in pure seminal plasma. In SMIS containing the total seminal plasma protein fraction or the <50 kDa protein fraction or in pure seminal plasma, significantly higher motility rates and swimming velocities could be activated than in SMIS without seminal plasma proteins and in SMIS containing the >50 kDa protein fraction. These preliminary results indicated that seminal plasma proteins have physiological functions in prolongation and stabilization of sperm viability when using sperm motility as viability index.
