Pleasure Meets Parenthood: Japan’s Underground Sperm Donor Creates Babies in Legal Grey Zone

Hajime’s private sperm service has led to 7 pregnancies and 4 births—exposing Japan’s fertility loopholes

19 August 2025, New Delhi

In Japan’s fertility deadlock, where single women and queer couples are denied hope, one man is offering it — through sex and sperm.

Known by the pseudonym Hajime , he offers women two choices: sex (natural insemination) or artificial insemination. His unconventional service has already resulted in seven pregnancies and four births, thrusting him into the spotlight of Japan’s fertility debate.

Trust Through Tests — And Sex

Unlike anonymous sperm banks, Hajime openly posts his monthly health check results (around 11,700 yen per test) and even his university diploma to reassure clients. “Transparency builds trust,” he says — a rare kind of honesty in an underground market often shrouded in secrecy.

Who Seeks Him Out?

His clients are mostly lesbian couples and single women—groups barred from accessing sperm donations in Japan’s clinics, which cater almost exclusively to married heterosexual couples.

With official artificial insemination by donor (AID) procedures plummeting in recent years, more women are turning to private arrangements like Hajime’s.

Babies in a Grey Zone

Japan has no law banning private sperm donation, but the practice floats in a legal grey zone. Without regulation, issues of health, paternity, and children’s rights loom large. Critics warn of risks, while clients see only hope.

Sex as Solution

For Hajime, his work isn’t scandal — it’s service. By offering sex or insemination, he fills a void Japan’s fertility system refuses to acknowledge.

And as long as laws lag behind, one man’s “sex-or-insemination” mission is quietly creating families — outside the system, but very much in the open.
