The Role of Anti-Müllerian Hormone in Van Cats in Relation to Sex and Reproductive Status.

The present study aimed to evaluate anti-Müllerian hormone (AMH) concentrations in female and male Van cats. The study included six groups: prepubertal female cats, pubertal female cats, spayed female cats, prepubertal male cats, pubertal male cats and neutered male cats. A total of 42 Van cats were included in the study, with 7 cats in each group. Blood samples were collected from the cephalic vein of all animals, and AMH concentrations were measured from serum using the ELISA test. The highest AMH levels were observed in the prepubertal cats (p < 0.001). AMH concentrations were 14.33 ng/mL in prepubertal female cats and 31.91 ng/mL in prepubertal males (p < 0.001). In pubertal cats, AMH concentrations were 6.61 ng/mL in female cats and 10.27 ng/mL in males, with no significant difference between the sexes (p > 0.05). The lowest AMH levels were observed in neutered cats (p < 0.001). AMH concentrations were 0.109 ng/mL in spayed female cats and 0.096 ng/mL in neutered male cats, with no significant difference between the two groups (p > 0.05). In conclusion, the highest AMH concentrations were observed during the prepubertal period in both female cats and male cats. Furthermore, prepubertal males had significantly higher AMH levels than female cats. Measuring AMH concentrations in Van cats may help determine their reproductive status (prepubertal, pubertal or neutered).
