“…Females were subjected to a standard breeding soundness examination, including reproductive health history, physical examination, transrectal ultrasonography of the reproductive system, and vaginal examination. Transrectal ultrasonography was performed using a 7.5 MHz linear transducer mounted on a PVC handle at intervals of 3 days for 2 weeks as described by the authors (18). A vaginal examination was performed with a sigmoidoscope.…”

Alpacas have a high incidence of congenital reproductive tract abnormalities, including ovarian hypoplasia/dysgenesis. Diagnosis of this condition is often challenging. The present study describes the clinical, ultrasonographic, and histologic features of ovarian hypoplasia/dysgenesis syndrome in 5 female alpacas. Additionally, serum AMH levels were compared between female alpacas diagnosed with ovarian hypoplasia/dysgenesis and a group of reproductively sound females (n = 11). The syndrome was suspected based on the presence of an infantile uterus and lack of ovaries by ultrasonography and laparoscopy. All females had normal female karyotype (n = 74 XX), but one presented a minute chromosome. The ovaries from these cases showed 3 main histological classifications: hypoplasia (n = 2), dysgenesis (n = 2), and dysplasia (n = 1). Serum AMH levels in affected females were significantly lower (P < 0.05) than those of reproductively sound control females. In conclusion, Serum AMH level may be helpful in the rapid diagnosis of ovarian hypoplasia/dysgenesis syndrome in alpacas. Furthermore, this syndrome in alpacas presents a variety of histological features. Different mechanisms may be involved in the derangement of ovarian differentiation. Further studies are needed to elucidate the causes of the syndrome.
