Our company endorses April Dream, an initiative to make April 1st a day for announcing dreams. This press release is a dream of "HDX Cell Bank Inc."
HDX Cell Bank Inc. (Headquarters: Shinjuku-ku, Tokyo / Representative: Toru Mukai) will hold the world's smallest competition, "SPERM RACING JAPAN GRAND PRIX 2026," in Tokyo this autumn.
This event is a new initiative aimed at opening up reproductive health (sexual and reproductive health) to society by observing and visualizing sperm movement in real-time on a silicon micro-course and turning it into a competition.
Sperm racing garnered significant attention when it was held in the United States last year. We will uniquely evolve this movement in Japan and present it to society as entertainment.
This initiative will make the theme of reproductive health more accessible and create opportunities for open discussion. At the same time, we support the life design of the younger generation by providing infrastructure that "preserves future options."
■ Background
While reproductive health is an important theme in an individual's life planning, opportunities for open discussion remain limited. Additionally, while preventive sperm freezing is beginning to attract attention as a means of preserving future options, it is still only chosen by a limited number of people.
However, this trend has certainly begun. Our company will transform this into a "new normal."
