Documented and anecdotal effects of certain pharmaceutical agents used to enhance semen quality in the dog

Prostaglandin F2α, gonadotropin releasing hormone, cabergoline and various nutriceuticals have all been recommended by reproductive practitioners to improve sperm motility and morphology and to increase sperm numbers in the ejaculate of the dog. Increasing sperm quantity and quality in the canine ejaculate would benefit all assisted reproductive techniques used in this species. The purpose of this manuscript is to review the documented and anecdotal effects of certain pharmaceuticals used to enhance semen quality in the dog.
