The relationship between sperm quality in cool-shipped semen and embryo recovery rate in horses. Academic Article uri icon


  • The relationship between the quality of cool-shipped stallion semen and fertility has not been adequately described. This study evaluated sperm quality of cool-shipped semen from 459 ejaculates (N=130 stallions) that were used for insemination of 196 embryo donor mares (n=496 estrous cycles). Embryo recovery rate (ERR; %) increased, as all sperm measures (e.g., motility, viability, DNA quality, morphology, concentration, and total number) increased. Threshold values are reported for each sperm quality measure (e.g., total sperm motility65%) that separate two ERR groups (e.g., average: 50% ERR; high: 65% ERR).
