Meet the men offering their sperm to strangers online – but only if they can do ‘natural insemination’

‘She got pregnant the second time we had sex. Her husband was in the house when we did it,’ says Terry*, who donates his sperm through natural insemination… also known as unprotected sex.

Terry, 39, had met the couple when they responded to his Craigslist ad entitled: ‘Looking to impregnate a MILF.’

Expanding on this, Terry wrote: ‘Man wanting to find a hot married MILF to let me cream-pie and impregnate her. Love the idea of f***ing a married wife with the goal of getting her pregnant. I can travel to you & just want to dump all my cum in your pussy and leave, no strings attached. I’m ddf [drugs and disease free] and you should be too.’



The couple, who were in their mid-30s, told Terry they’d been trying to conceive, but hadn’t had any luck. Tests suggested the issues were on the husband’s side, which was where Terry came in.


Terry tells Metro.co.uk: ‘I was hoping for a bit more fun, but it worked too well!’

This isn’t the only time Terry’s delivered the goods. Six months previously, he impregnated a woman in a lesbian relationship, whose partner believed the sperm was inserted artificially.

Terry says the woman had never had sex with a man before, but her response to his ad was ‘one of those where they really want a child and they’re willing to go through with everything else that comes with that’.

Six weeks later Terry received a text confirming the woman was pregnant.

‘I texted her back but she didn’t reply and the number’s disconnected now,’ says Terry. Terry, who had no intention of contributing financially and never wanted any involvement in the child’s life, adds: ‘I feel a bit short-changed by the radio silence.’

Despite his disappointment, Terry hasn’t lost his stride. ‘Sex is enjoyable — bareback sex even more so,’ he tells us. ‘And if you add the heightened risk of pregnancy when no contraception is used, it really takes it to the next level.’

Tim’s Craigslist ad is entitled: ‘Feel me come inside you.’ It describes ‘filling you with warmth, wetness and cream’ and refers to leaving respondents ‘full of semen.’

He’s had a response from a lesbian/bi couple who want to conceive, and he’s currently considering it.

‘I’m talking to them,’ says Tim, ‘but there’s a legal complication about sperm donorship which is that if you just donate it, that’s fine, but, as I understand it, if you deliver it the natural way, in law you are the father and liable for child support. I’m getting further legal advice before taking it all the way.’

Having initially interviewed Terry and Tim while researching a feature for Londonist, I went on to speak to a dozen more would-be natural inseminators in the course of an undercover investigation for Cosmopolitan. Out of all the men whose ads I answer, Tim turns out to be the only one who has thought about the consequences.



‘Fertile woman wanted for breeding,’ says one ad, posted by a 57-year-old in Surrey, who explains, ‘I’m in a relationship but the desire to breed is taking over.’

A 44-year-old divorcee says: ‘I’m happy to come and frequently have sex til you get pregnant.’

And perhaps in an effort to capitalise on Brexit, one guy asks, ‘Do you want a British baby? Any tourists in London wanting to get impregnated by a British male? Willing to meet you several times while you are in town until we reach our goal.’

These are just a few of the ads I browsed before responding and meeting up with several guys in person. Putting myself in the shoes of a woman viewing this as an option, here are some of the questions I asked:

Would they be willing to contribute financially towards the baby? Perhaps they’d buy the odd birthday present or pair of shoes?

‘Well I’ve been setting my mind on going to live in China,’ says Gary, who is in his early 30s. ‘I was looking to help people who was ok bringing up the child. Sorry, trying not to sound harsh.’

‘The odd present, I guess – not thought of contributing,’ says a 41-year-old whose ad announces, ‘I am turned on by making a stranger pregnant. I would love to unload my seed in a woman any age or size.’

‘You can claim money from the government. They pay you £120 a week,’ says a 28-year-old from Essex whose ad promises to ‘f*** you every day till your pregnant, any looks or weight I will give you my cum… I done this a few times and there a lot off happy mums, just to say once we done the deed we never meet again.’ (sic)


‘I’m a father of three, I can’t afford any more,’ says Steve, whose wife of 15 years is unaware that he’s offering to get other women pregnant.

But where do they stand legally? Elizabeth Hicks, Head of Family Asset Protection at law firm BCLP says that if the man is proved to be the father, then he has financial responsibility for the child – even if he’s stated that he wouldn’t want to contribute.

Hicks tells Metro.co.uk: ‘the court looks at what’s in the best interests of the child – and the child’s welfare is paramount.’

Would they be want to be involved in the child’s life?

‘Never thought about it, but I’ll defo supply the sperm for you,’ says a 41-year-old, who repeatedly offers to give me his load.

‘This is something we can work out and discuss,’ says Kevin, 42, whose ad says he’s married. Is this something he’ll be telling his wife about? ‘For the time being it is probably best being discreet,’ he says.

‘No ongoing involvement thereafter,’ says a 48-year-old from East London, echoing his ad which states, ‘prepared to help you achieve your goal without any ties for the future.’

Have they fathered kids before – and if not, how do they know their swimmers are fully functioning?

‘I don’t have my own kids but I helped a couple with my sperm. We had a great time,’ says Carl, a 28-year-old I’ve met in Costa Coffee, who looks at me like he might kiss me.

‘I’ve got an old f*** buddy pregnant, so yes it works,’ says my favourite 41-year-old. And does he see the child? ‘She didn’t want me to, so no.’


‘I have two kids and I’ve helped with three pregnancies, so I’m very fertile,’ says Greg, a 40-year-old divorcé who I’ve met in another coffee shop. He shows me pictures of his kids, while looking at my breasts.

Would they be willing to have their name on the birth certificate?

Aside from Carl, who wants me to be his girlfriend, the answer is pretty much no.

But can these natural inseminators legally keep their names off the birth certificate, if the mother wants to include it?

Hicks says: ‘The birth certificate is a record of who the parents are, so if the man is proved to be the father, I don’t think there’s anything he can do.

‘Even if he said, “don’t put my name on it,” and they’d agreed on that, if he’s the father, that’s tough luck to him.’

Would they give me their sperm for artificial insemination, instead of us having sex?

‘I’m not open to AI – natural insemination is what I prefer,’ says a separated 55-year-old whose ad invites prospective mothers to ‘run away to Spain to breed in the sun.’

‘Just looking for a sexual meet really, with the added result of helping someone get pregnant,’ clarifies a 29-year-old from Herts who includes a dick pic in his Craigslist ad.

‘It would be more reliable if I insert it during sex,’ says the 41-year-old, who suggests the following compromise: ‘How about we meet, and if we get on I put my seed in you, or if you choose, I go to the loo, wank in a syringe, and you can put it in you?’

‘I love the idea of helping a woman to be pregnant,’ says Greg. Great! Surely Greg will consider artificial insemination? Er, no. Why’s that then, Greg? ‘Because I love sex!’ So it’s not all about the babies? ‘Two birds, one stone!’

For any men considering fathering extra-marital babies via natural insemination, I’ll leave you with a word of warning from Hicks.

She says: ‘I’ve had male clients who, when they’ve been married, have gone off, had unprotected sex, and a child has been born. Their partner has then left them, and they find themselves having to deal not only with their divorce, but also a claim from the woman they had unprotected sex with.

‘That one moment of madness has potential ramifications for the rest of their lives.’
