The news deals with the increasing acceptance and usage of donor sperm in Japan, particularly among men diagnosed with azoospermia (lack of sperm). The trend is fuelled by advancements in medical technology, supportive health policies and evolving societal norms regarding family planning. The focus is on the emotional and social aspects of these 'new dads' navigating through their unique parental journey.

In Japan, infertility treatments and artificial insemination are slowly gaining acceptance as solutions for couples with fertility issues. The stigma surrounding infertility is lessening, with more emphasis being placed on the importance of family creation, irrespective of biological connection. The health and happiness of the child is the foremost consideration.

In the US and EU, sperm donation and artificial insemination are more widely accepted, regulated, and both the donors and receiving families are protected by laws. The concept of ‘family’ is broader, with adoption and assisted reproduction methods being common.
