The sperm quality supplied by producers is an urgent problem in the field of livestock breeding. Therefore, monitoring the health of male producers and sperm quality is of great priority. The study aimed to assess the reproductive performance of bulls using laboratory, clinical, morphological, ultrasound and reflexological techniques. A total of 17 heads of Kazakh-white-headed, Holstein-Frieze and Simmental breeds were studied. The quality of sperm was evaluated by the laboratory, clinical, morphological, ultrasound and reflexological diagnostic methods were used to determine the physiological state of the genitals. The results revealed that 11 (65%) bulls were included with high and good reproductive bulls and 6 (35%) with reduced reproductive abilities. The reliability of the measuring method for the morphological development of the scrotum and ultrasound coincides with the data of sperm quality by 66.6% and studying sexual reflexes on a point scale by 50%. When assessing the male reproductive performance, measuring the morphological development of the testes, studying sexual reflexes on a point scale and ultrasound examination of the testes and their appendages are recommended.
