Japanese celebrity "Messenger Kuroda" has openly discussed his experiences with fertility treatment in a rare move for the traditionally private Japanese society. Kuroda's decision to address this personal matter publicly is seen as an attempt to dismantle societal stigmas attached to infertility and the usage of infertility treatments. The time and venue of the discussion have not been explicitly mentioned in the headline.

In Japan, personal matters are often kept private, especially life challenges such as infertility. An open discussion by a public figure about their own experience can play a significant role in Japan's societal norms, potentially helping to change public attitudes towards infertility and its treatment. It also raises awareness of the emotional and physical challenges associated with infertility, and can help individuals and couples dealing with similar issues feel less alone.

In the US or EU, infertility is less of a societal stigma, with many public figures and celebrities openly discussing their struggles and treatment journeys. These frank discussions have prompted societal shifts in understanding and accepting infertility as a medical issue, not a personal failure.
