Transrectal ultrasonography is a technology used in cattle reproductive management as a means of gestation diagnosis and estrous cycle monitoring. Likewise, it has application in the management, diagnosis and treatment of both reproductive processes and in reproductive biotechnology programs. The objective of the work was to carry out a bibliographic review on the reproductive processes in cows and the ultrasonography use. A bibliographic review was carried out including publications from 2022 and previous years. Criteria that support the development achieved in the use of ultrasound were considered, based on the logical analysis of the consulted bibliography. The keywords used were ultrasonography, ultrasound, cattle, bovine reproduction, transrectal palpation, estrous cycle, follicular dynamics, ovarian function, Doppler, corpus luteum functionality, early pregnancy diagnosis, embryonic death. Transrectal ultrasonography has increased our knowledge and understanding of bovine reproductive physiology. Technological advances have allowed its use in the reproductive management of cattle to increase. Ultrasonography is a revolutionary advance in research that has influenced the efficiency of cow reproductive management.
