A project aimed at developing a semen preservation method for artificial insemination in dairy cattle—drawing on insights into mammalian sperm motility mechanisms from the research group led by Professor Masayuki Shimada at the Graduate School of Integrated Sciences for Life, Hiroshima University—has secured a three-year grant of approximately 1.8 million US dollars (approximately 260 million yen as of October 2025) from the Gates Foundation.

In connection with this achievement, a press briefing was held on Thursday, November 27, 2025, at the TKP Shimbashi Conference Center. A video recording of the briefing has been released as part of this press release report. We invite you to view it.
