DILUTION OF SEMEN

Introduction

• The purpose of diluting semen is to extend its volume so that many females can be bred from a single ejaculate.
• Fluids used for diluting also prolong the life of sperm, provide energy to the sperm and one of the ingredients acts as a so called ‘buffer’.
• The purpose of the buffer is to keep the fluid at the degree of alkalinity necessary to preserve the life of the sperm.
• Such extenders are used to preserve its fertilizing capacities throughout the various procedural stages necessary prior to its proper introduction into the female reproductive tracts at estrus.
• Dilution and preservation of semen is carried out with suitable media, which are non-toxic and provide nutrients for the maintenance of spermatozoa along with egg yolk.
