A 38-year-old office worker in Japan is offering an unconventional form of sperm donation by sleeping with women to help them conceive
The man, known only by his alias Hajime, also provides a no-sex insemination option.
According to South China Morning Post, his unusual journey began five years ago when an infertile university friend made a desperate plea.
"My university friend told me he lacked sperm and could not have children with his wife, and then he asked me to sleep with her and get her pregnant," Hajime told Kansai TV.
Although initially shocked, Hajime agreed. After the child was born the following year, he saw his friend's gratitude and joy, which inspired him to anonymously offer his services on social media.
To build trust, he regularly uploads his monthly infectious disease test results, which cost around 11,700 yen (RM335) each time
He also shares his university diploma online to prove his integrity.
Hajime offers his services for free, only requesting a minimal payment to cover travel expenses. He has reportedly helped seven women conceive, with four having already given birth.
While he expected most of his clients to be infertile couples, Hajime found that the majority are female same-sex partners and single women who want children but not marriage
His service offers an alternative, as Japan has legal restrictions on fertility treatments for unmarried women and same-sex couples.
The practice itself operates in a legal grey area and is not explicitly prohibited, with no laws explicitly governing private sperm donation.
Despite the controversy, Hajime says his motivation is not financial.
"When I see clients get pregnant and give birth, I feel deeply satisfied, like I have made a contribution to society," he said.
