Equine Spermatozoa at Optimum Physiological State Are Selected by Chemotaxis Toward Progesterone

The success of assisted reproduction techniques depends in part on sperm quality, which influences not only fertilization but also embryo development and implantation. In our laboratory, we designed the Sperm Selection Assay (SSA) based on chemotaxis towards progesterone, which selects human sperm at optimum physiological state (capacitated, with low levels of DNA fragmentation and reactive oxygen species). The aim of this study was to define the experimental conditions to apply the SSA in unsexed and sexed equine sperm samples.
