One man is taking “be fruitful and multiply” to a whole new level.

Rob Albon has devoted his life to supporting a controversial effort by the world’s richest person, Elon Musk.

Albon, who lives in a modest home in England, has nowhere near the wealth or name-recognition of the tech billionaire, but he has thoroughly outperformed Musk in their shared goal: to combat rapidly declining birth rates by repopulating the Earth with their children..

While Musk’s 14 kids have scandalized many, Albon says he has fathered a whopping 190 children.

“I’m the poor man’s Elon Musk,” Albon, 54, told the Daily Mail.

“Like Musk, I’m a very creative person. I feel I have to give back to the world, and this is my way: to be productive,” the prolific “Sperminator” explained. “It’s something I feel I should accomplish. I have some responsibility to my ancestors and their descendants. Filial piety is what it’s called. I’m doing it for posterity.”

Albon has developed a unique strategy of fathering his kids; as a private sperm donor, he publicizes his services on a Facebook page. He is one of the many unregulated sperm donors who practice natural insemination — regular penetrative sex — or partial intercourse, which entails penetrating at the last second for insemination.

Despite not being a practice done at any legal sperm donation sites, Albon argues that insemination through sex is best, claiming without proof that fresh semen and certain sex positions are more likely to get a woman pregnant.

Albon’s favorite perk of the job: enjoying his work.

“Of course, I like sex. It’s a creative thing,” he confessed to the Daily Mail.

“The women enjoy it, too. Some of them have told me.”

Since he moved to the UK from the United States in 2020, Albon has fathered around 40 kids. The majority are back in the U.S. or Argentina, where he previously worked as a translator.

While he is reportedly in touch with around 60 of his sperm donation kids and sees one of them a week, he has become estranged from his two children from his 30-year marriage with his ex-wife — because of his sexual hobby.

Albon’s “sperm donation” was exposed in February when a Welsh judge publicized his name in a judgment to warn women about his practices. Charging women $133 per session plus expenses, he went by the alias Joe Donor.

He sued a lesbian couple in 2023 for parental rights, demanding that his name be put on the birth certificate of a baby produced from a sperm donation.

Deputy High Court Judge Jonathan Furness KC blasted the father of nearly 200 as having “a complete absence of sensitivity or empathy” — a claim Albon has rejected.

“It’s ridiculous,” he said. “The judge is definitely wrong. A child has the right to an accurate birth record. My name should have been on the birth certificate, but another person’s name was on it, and she had no right to be there.”

Albon added that as a private sperm donor, he has the right to remain anonymous.

“He said he was naming me to protect women from me, but it drew me to the attention of more people who wanted my help,” Albon continued.

Despite his insistence that he wants to be on the birth certificate for his children, Albon is on the run from an arrest warrant in Wisconsin for six counts of not paying child support, the Daily Mail reported.

After the court ruling, he began scaling back on his sperm donation activities, relegating his services to creating siblings of his other children.
