The self-proclaimed “miracle maker” who plans to father up to 2500 children has been labelled as potentially dangerous and a risk to women’s health, after wrapping up his sperm donation tour down under.

Known only as ‘Joe Donor’, the international sperm donor arrived in Australia in January with a mission to get as many women pregnant as possible.

Meeting with Joe in the midst of his crusade, 60 Minutes reporter Liz Hayes called time on his behaviour, criticising his methods and his seeming lack of regard for the health of the women he impregnates.

“You are risking women's lives by your very deliberate actions,” Hayes fired.

“You are not helping anyone. You liken yourself to some doctor on call for desperate women.”

Joe Donor – who doesn’t use his real name and identity – has fathered children across the United States, South America and Australia. So far he estimates that more than 800 attempted inseminations have resulted in more than 100 children.

“I’m basically only having sex to get women pregnant. I’m not chasing rainbows or fantasies,” he told Liz Hayes.

While Joe offers his sperm to women for artificial use – at no cost other than reimbursement of his expenses, he claims that natural insemination and unprotected sexual intercourse is a more “effective” way of getting pregnant. Joe says that half his clients opt to use the natural method.

Joe’s scheme is unconventional at best, and dangerous at worst.

Family and fertility expert and lawyer, Stephen Page, is outraged, saying Joe is putting vulnerable women and their potential children at serious risk.

“He's really playing the role of God, and he shouldn't be playing the role of God towards desperate women and their kids,” Page told Hayes.

“I just think he's mad, and dangerous, and these women shouldn't be going anywhere near him.”

But what has eyebrows raised is Joe’s somewhat dismissive attitude towards women’s health and proper medical checks.

“Some people they want to do a background check, a drug test. And I’m like you know you’re not giving me the keys to the nuclear missiles – we’re just making a baby,” said Joe.

Joe Donor believes that medical checks and screenings for sexually transmitted infections are all part of a conspiracy by IVF clinics to make money.

And while he says he gets tested once a year for STI’s, the rate at which he has unprotected sex could be putting all the women he sees at risk of any number of sexually communicable illnesses.

“If he's having sex a number of times a year, and it's unprotected, and in the process he's not getting checked, what do you reckon?” Page told Hayes.

“Sooner or later, the odds are he may well have HIV and transmits that to someone else. What a disaster.”

For Melbourne woman Sharney, Joe Donor offered an opportunity she felt she couldn’t refuse.

Sharney and her partner desperately want a child but initially felt they could neither afford the cost nor the waiting period at an IVF clinic.

In steps Joe Donor, who after meeting Sharney for less than an hour provides her with a syringe of his “super-sperm”.

Sharney, who opted for artificial insemination from Joe Donor, said she had assumed Joe had all the necessary medical checks – but was provided with no proof.

“It was paramount that he was healthy. That he had all of his medical checks, as in I wouldn't be put into danger,” she told Hayes.

“We honestly thought that being so open and public, that he would have to be [checked].”

But after her insemination failed to result in a pregnancy, Sharney and her partner began to have second thoughts about Joe and his methods.

“What is he getting out of this? I’m honestly not really sure, it’s really strange.”

Sharney and her partner have since decided to seek help to extend her family at a fertility clinic.

Liz Hayes was unrelenting in her questions of Joe Donor, putting to him the severe potential consequences and risks of his behaviour.

“You’re putting women’s health at risk,” Hayes said.

“The real risk is that a woman will die a spinster without a child,” Joe said.

“The real risk is that you’re totally deluded,” Hayes fires back.
