The news revolves around a Japanese man who, at the age of 29, unexpectedly discovers he was born using donated sperm. This revelation surprises him and provokes mixed feelings.

In Japan, donor anonymity is a standard practice for sperm donors, yet there's an ongoing debate concerning its implications on the psychosocial development and identity of donor-conceived children. People tend to empathize with the man's situation, while acknowledging the necessity and the complexity of donor anonymity policies.

In contrast, countries like the US and EU have varied approaches towards sperm donation. Some protect the donor's anonymity, whilst others like Sweden and UK, enable children to learn the identity of their donor when they come of age. It's a complex issue, managing the interests of donors, parents, and donor-conceived individuals.
