In the last decade, different insemination techniques, which permit the use of lower sperm numbers, have evolved in several species, primarily livestock. Low-dose insemination is preferred for several reasons:(1) The emerging use of sex-sorted sperm in various species due to the todate limited sorting efficiency and the harvest of sperm with poorer quality, (2) The increased efficiency of the use of males with the consequent reduction of fixed costs and reduction of the female population, (3) The acceleration of genetic progress by frequent use of higher indexing sires (4) The increase in the availability of semen from males in high demand,(5) The use of low-quality semen from genetically valuable males, or (6) The use of epididymal spermatozoa, usually only available in limited numbers after a terminal semen collection. Insemination of sperm in low numbers requires semen deposition close to the site of fertilization at an optimal time relative to ovulation.،
