HDX Cell Bank has launched WHO standard semen analysis and sperm DNA fragmentation index (DFI) tests as a corporate health checkup option. Utilizing a home collection method, it eliminates the need for clinic visits, promoting awareness of male reproductive health.

Amid international reports pointing out the decline in male sperm function, HDX Cell Bank Co., Ltd. (Headquarters: Tokyo, CEO: Toru Mukai) has launched WHO standard semen analysis and sperm DNA fragmentation index (DFI) tests as corporate health checkup options. Utilizing a home-based method with specialized collection and transport equipment, the tests can be conducted without the need for a clinic visit, drawing attention as a new initiative to visualize male reproductive function.

Background In recent years, the decline in male sperm function has been pointed out globally. On the other hand, in Japan, opportunities to understand one's own reproductive function are limited, and issues related to pregnancy and childbirth often only become apparent after entering the stage of fertility treatment. Furthermore, while women's awareness and options regarding reproductive health are advancing due to the spread of Femtech and egg freezing, the visualization on the male side is insufficient, creating an information gap between men and women. Against this background, there is a demand for foundational infrastructure that allows both men and women to jointly consider preparations for pregnancy and childbirth.
