Fiancé insisting on donating sperm against my wishes

241 replies

He won’t back down. I have said multiple times that I don’t support this, we already have a lovely child together and for medical reasons I cannot/won’t risk carrying another baby myself. He keeps asking me to put myself as risk by having another child and because I won’t he has decided to donate sperm.

With DNA ancestry testing, anonymity is no longer possible, and our child could end up with half siblings all over the world. The donor children may get in contact with our family in the future, seems like emotional turmoil waiting to happen and a massive shock for our own child. He’s already started the process and is putting his foot down. It’s causing huge arguments. He said he is determined to carry on as it is his life goal to have lots of children and won’t stop this process.

He had an affair which I found out when our baby was a few weeks old which was devastating and is another reason why I refuse to have another child with him as I don’t want to put myself in a vulnerable position again. We have worked hard together to rebuild trust for me to forgive him after the affair betrayal and now this insistence on sperm donation has made me feel depressed and worthless. Like my opinion doesn’t matter in the slightest…

He wants another child and this isn’t an option for you. Looks like there’s nowhere to go sadly.

Thank you so much for all your replies, I have read them all. Really grateful for the support and clarity on what feels like a very weird situation that I’m ashamed to bring up in conversation IRL.

To answer a couple of questions - no we are absolutely not getting married.

I have no idea if this whole donation thing is to cover up a potential child that pops up down the line from an affair. I suspect not, as mentioned by a PP dates wouldn’t work.

All the references to Elon and ‘What in the Elon Musk is going on here?’ Really made me laugh. Thank you for making me smile in this stupidly shitty situation.

This in spades. ^ I am furious on your behalf @Shitehound He sounds like an utter arsehole. OMG, your post has angered me so much. 😠You deserve soooooo much better. What an absolute tool wanting to donate sperm 'to make more babies!' He is very unlikely to meet them, unless they try and trace him in 18-20 years. Is he gonna play daddy then is he? 🙄

WTAF have I just read? Please don't stay with this man OP. He does not love and respect you. ❤

Same, I really feel pissed off on behalf of the op x

Your opinion doesnt matter to him.

Sorry OP, please dont marry him

Owl55 · 16/08/2025 14:37

Are you sure he hasn’t got someone else pregnant and will pretend it was a sperm donation not an affair??

He can donate sperm, you can’t stop him, but you can walk away and refuse to be with him. I couldn’t be with someone who donated sperm, I think it’s ethically and morally wrong and I wouldn’t like the idea of random children turning up in future.

For some people its there only chance of having a child following unavoidable medical treatment.

Hopefully in 20 years time he has a long queue of young people trying to contact him and demanding lot of attention and, who knows, the odd £1000,000!!

This is what went wrong with sperms donation. Must've put off a lot of prospective donors who are merely trying to help others if they then can be tracked down and made demands of

Sperm donation can lead to another person, that person has a right to know where they come from.

Not enough thought was given to that when sperm donation started to be a thing.

And I think most donors see/saw this as easy money, I don't for one minute think it was altruism.

Didn't think they got paid tbh

I'm sure it was a quick and easy way for students to make a bit of cash back in the day - I don't know if it's still the case though.

What a twat

MsSmartShoes · 28/08/2025 22:47

Leave him now! Thank your lucky stars you were you warned before you married him. Move on, don’t look back.

mumofoneAloneandwell · 31/03/2026 18:07

What was the outcome op @Shitehound - hope you left his arse? xx

Bimblebombles · 31/03/2026 18:40

I would say from what you've shared already that the likelihood is he will cheat again in the future - self obsessed, intent on procreating, already had one affair, puts you at the bottom of the priority list.

Protect yourself from him and part ways.

hepsitemiz · 03/04/2026 19:00

I’m sorry OP, but he sounds like some perverted misogynist from the manosphere. You have my deepest sympathy. I hope you are able to extricate yourself and your baby very soon xxx

Diamond7272 · 03/04/2026 19:30

He sounds plain creepy.

Not on normal court exercise I presume.
