Plain-English summary
Two American Paint Horses, a 3-year-old and a 7-year-old, were brought in for infertility issues during their pre-breeding exams. The veterinarian used ultrasound and physical exams to check their reproductive systems and found that one mare had a condition called uterus unicornis, meaning she only had one functional uterine horn. Unfortunately, this condition was confirmed after the mare passed away, revealing that the right uterine horn and oviduct were missing.

Abstract
Two American Paint Horses, a 3-year-old nulliparous mare and a 7-year-old primiparous mare, presented for recent infertility and a pre-breeding examination, respectively. Examination of the internal reproductive tract of both mares using transrectal palpation and ultrasonography revealed the presence of the cervix, uterine body, left uterine horn and bilateral ovaries. The right uterine horn could neither be palpated nor imaged. The clinical diagnosis of uterus unicornis in one mare was confirmed at necropsy, which revealed combined aplasia of the right uterine horn and oviduct.
