Examination of the stallion's reproductive tract involves assessments of external and internal anatomy. External examinations are performed by visual inspection, palpation, or ultrasonography and include the scrotum, testes, epididymides, penis, and prepuce. Internal examinations may be performed by rectal palpation, transrectal ultrasonography, or endoscopy and include the accessory sex glands, pelvic urethra, and inguinal rings. A fertile stallion must produce, transport, store, and deliver viable spermatozoa to the mare. The physiologic processes involved include neuroendocrine control, spermatogenesis, sperm maturation, semen delivery, and fertilization.
对公马生殖道的检查包括对其外部和内部解剖结构的评估。外部检查通过视诊、触诊或超声检查进行，包括阴囊、睾丸、附睾、阴茎和包皮。内部检查可通过直肠触诊、经直肠超声检查或内窥镜检查进行，包括附属性腺、盆腔尿道和腹股沟环。一匹具有生育能力的公马必须产生、运输、储存并向母马输送有活力的精子。所涉及的生理过程包括神经内分泌控制、精子发生、精子成熟、精液输送和受精。
