Libido, Erection, and Ejaculatory Dysfunction in Stallions
Sue M. McDonnell, Ph.D.
Continuous access to mares and skillful handling are generally the best approaches to dealing with inadequate libido in stallions. Although the problem can occur in experienced stallions, it is more common in slow-starting novices. Erection dysfunction primarily occurs subsequent to traumatic injury of the penis, such as kick injuries or semen-collection accidents. Ejaculation dysfunction can result from neurologic and musculoskeletal or ejaculatory apparatus problems.
