Fiancé insisting on donating sperm against my wishes

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 keeps asking me to put myself at risk “

That one line alone is enough to leave him. You can’t control what he does but you can control what you do. Role model to your child that we don’t settle for mediocrity.

What an utterly awful human being your fiancé is. Please don’t marry him, just run very fast in the opposite direction. He doesn’t love you. He doesn’t even like you. This is not a relationship it’s a nasty vindictive game to him.

This. It smacks of 'punishment' to you for refusing him another child. That's really bloody awful.

PeonyPatch · 14/08/2025 06:35

Why are you still with him?

StrandedInJune · 14/08/2025 06:36

My brother donated and I have always felt unhappy about it, especially since having children and since he has had children with his wife. To think that I have nieces and nephews out there who could turn up, who my children could end up dating without realising they are first cousins really unsettles me. I also think of my mother who is their full grandmother. And what of his children with his wife? They could have hundreds of half brothers and sisters somewhere in the world. These are his children! I don’t know how men reconcile this. I would be traumatised to think my own children were out there somewhere and to not even know how many and where. So… OP YANBU. There are so many implications of this and men who do this without consideration for their families are totally selfish and inconsiderate. If my husband did this it would be over for me.

I'm hugely in favour of sperm donation given it gave me my two kids (though I didn't feel comfortable donating my spare eggs which made me feel a bit hypocritical but also highlights its a super personal choice) - but this is weird and concerning. Prioritising donating sperm to anonymous recipients over the concerns of the mother of your existing child is completely cuckoo. Sperm donation is a generous thing to do when altruistically motivated - but off-putting when it comes from the "I want to spread my seed" mentality. I also agree with the other poster who said that under UK rules the likelihood that your child end up with loads of "diblings" (donor half siblings) is pretty low so I wouldn't worry too much about that - its the motivations here that are more worrying.

Obviously the fact that he cheated on you whilst you were pregnant the first time and he seems to be bullying you about additional children is even worse. I'd sit back and evaluate what you really need out of the relationship and if you will ever be able to get it from him.

Rocknrollstar · 14/08/2025 06:41

And you are going to marry him?

ThisOldThang · 14/08/2025 06:42

Our children were born due to the generosity of an egg donor. I don't consider sperm donation to be an inherently bad thing.

This is a very weird situation, though. There is already a child in existence that will be impacted by any future donor children. His motivation seems very odd - was it said in jest? If he's serious, I don't think this is a healthy relationship.

Thank you for all your replies. Just quietly sobbing with reading all your lovely, and accurate comments. I know in my heart this is the final nail in the coffin. He actually yelled at me earlier because I asked ‘Why can’t you put me first?’ He’s also a complete workaholic and I’m really lonely. Would rather be a single mum than carry on like this.

Our child is primary school age. I earn ok money. It will be tight but you are all right I need to end this, he really doesn’t give a fuck about me. Thank you

I'm glad you can see what you need to do, because you really do need to end the relationship. He'll destroy you mentally, otherwise, eventually.
Sending you lots of strength to get through this! You deserve a happier life.

Why oh why do we have so many threads in mumsnet where woman are with such horrible men? Is being single really worse than being with someone who has zero respect for you?
OP- he is treating you as a vessel to provide a child and not as a partner. Please leave him.

I agree, it’s depressing. As someone who had to divorce my abusive ex after having a child together, I think honestly it’s for one thing simply because so many men ARE horrible, and in particular they are horrible to the women in their lives sadly. I never understood Germaine Greer saying that “women have very little idea how much men hate them” when I was younger, but I really do now. I genuinely now feel there is a large minority of men out there who would happily rape women left right and centre if society completely broke down tomorrow resulting in it being easy to achieve without fear of reprisal or consequence.

I do know it’s not all men and thankfully I have an absolutely amazing father for example. But domestic abuse isn’t happening in a vacuum. Men are in general physically superior to us, and we still live in a patriarchal society. Yes, the bar should be much higher for men in general. But I don’t know how we achieve that and certainly it will take time to dismantle the patriarchy completely. I’m trying to do my bit in raising a son who has deep respect for women and girls.

I also think that due to the patriarchy, many women are and certainly were in the past, socially conditioned to be people-pleasers, kind, caring and hospitable people who need to avoid showing anger, or any emotion or behaviour that could come under societal misogynistic concepts and tropes such as “the nag”, “the bitter shrew” etc, and in particular to put a partner’s needs and wants ahead of their own. And also that marriage is the pinnacle of achievement for a woman (I do think we’re making progress on that one but concepts like being “left on the shelf” as a “spinster” still linger, as well as the much higher frequency of young women being asked when they’re going to marry and have children compared to young men in the same settings etc. I definitely felt significant social pressure in my social circle to marry in my early 20s or be considered by mid-20s to be really risking a lifetime as a spinster etc. Which yes, I saw as a terrible fate at the time in a way I don’t necessarily nowadays.

I also think we don’t do a good enough job of educating young women in recognising domestic abuse and conversely a healthy relationship, boundary-setting etc, and we also aren’t doing a good enough job in raising young men to do better for the next generation.

This is simply the result of all of this and part of VAWG. And even if we aren’t talking about actual abuse, the rest of generally crappy behaviour in men is just the tail end of that showing.

I guess it’s also important to point out that abusive men don’t tend to show their full colours right away. Of course it’s hard to understand why OP is in this sort of relationship from the outside. But he may have started out appearing to be Mr Right and a dream come true in every way. When I married my ex, he said all the right things about women etc, treated his mother really well, my family had no concerns. Somehow we went from that to his telling our marriage counsellor (before I’d fully woken up to the reality of it being an abusive relationship) that “the problem is, that she is a feminist”. The female counsellor was like “Ummm and why is that a problem exactly?!” 🤣

cosietea · 14/08/2025 06:52

It’s giving sexual predatory vibes. At the very least he’s see’s women as baby factories
Walk away today, take back control and don’t back down. Make your decision, stick with. Your child will be worse off staying in this situation

RampantIvy · 14/08/2025 06:57

I also think we don’t do a good enough job of educating young women in recognising domestic abuse and conversely a healthy relationship, boundary-setting etc, and we also aren’t doing a good enough job in raising young men to do better for the next generation.

I agree. This is so depressingly evident on far too many threads I read on MN from women in abusive relationships.

JustPinkFinch · 14/08/2025 06:59

This man is not going to be your all-life partner. Everything you have said makes that clear. Please cut your losses now, don't drag it out.

MalcolmMoo · 14/08/2025 07:08

In isolation I’d say YABU because he can donate sperm if he wants and that’s his choice BUT given his motivation for it being he wants lots of children and that he’s doing it to spite you because you can’t have any more because of medical reasons etc. and the fact he sounds like an a*hole with the affair Yanbu! Personally I’d be looking to leave him I could not stay with someone like this

Divorce op.

He's determined to procreate loads of children but has zero interest in actually parenting them? And will do it at the expense of the child who he is actually supposed to be parenting?

This sounds like some sort of weird ego rub or kink to be honest and yes I'd leave over this if he was determined to pursue it.

How absolutely traumatic for you as well, first the horror of realising he's had an affair when you are at your most vulnerable and dependent on him (I had the same experience- it's utterly devastating) and knowing you were forced to complete your family earlier than you'd expected to as a direct result of his behaviour (same here it is definitely a form of grief) for him to then decide he's going to do this.

I'm sorry op but that's a massive re-traumatising betrayal and you're absolutely correct to have the fears you have both for the impact on your child and your family.

He seems absolutely self- focused and like he has no ability to prioritise his family so I'd be quietly making plans to leave.

There's something feels very insidious about this that I can't put my finger on that sits very uneasy. I would seek legal advice, and support of a few friends who you know can keep their mouths shut and leave when he doesn't expect it.

How old is your child and do you have access to your own money?

How can you divorce someone you are not married to?

Mintytoothpaste1 · 13/08/2025 22:28

God he sounds absolutely awful. Really, really awful.

This. Twat with a capital T. Urgh.

TimeForATerf · 14/08/2025 07:15

If, this is true, why on earth are you with him? Ridiculous.

400rider · 14/08/2025 07:25

Oh dear. I feel for your dilemma. He already sounds very much thoughtless about others, not just you or your child but the impact of the surrogate child and his reaction if it does (or doesn’t) make contact in the future.

Financially he is responsible for your child and that must get cleared up soon.
If he does get accepted for his whim of populating the world you can only hope any hopefuls will turn his ‘package’ down and his efforts will be down the drain- so to speak.

Walk away, because you are clearly unhappy with this man

tara66 · 14/08/2025 07:32

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!!

Iceandfire92 · 14/08/2025 07:34

I think you should leave him regardless of whether he decides to persue this. I suspect his desire to sire multiple children doesn't derive from wanting to help women become mums, I believe it is far more nefarious and he has a breeding fetish. What an odious man! I imagine he is the type to iterate about his legacy being passed on despite being painfully average.

It is evident that he views you as nothing more than breeding stock; you are now no good to him as you are quite rightly refusing to have any more. This speaks volumes about how he views women.

ChaToilLeam · 14/08/2025 07:38

He sounds awful on so many levels.

AuntyDepressant · 14/08/2025 07:44

Well putting aside everything else - if we were talking about donating eggs everyone on here would be saying 'your body your decision' and 'it's nothing to do with him.'

MrsMitford3 · 14/08/2025 07:49

It seems to me he is scattering sperm far and wide in case any "children" find him he can say its is innocent-whilst cheating on you. This way if he gets anyone else pregnant by cheating on you he has a ready made cover story,
completely revolting.
You deserve better.

Imbusytodaysorry · 14/08/2025 07:50

Mintytoothpaste1 · 13/08/2025 22:28

God he sounds absolutely awful. Really, really awful.

I agree!
op you need to leave him. Gebuinley you do .

Spreading his sperm around one way or another is all that matters to him .
It’s really weird!

JamPotJenny · 14/08/2025 07:52

What have I read? I’m so sorry OP. I hope you’re ok 🩵

InterestedDad37 · 14/08/2025 08:02

The end result is the same - he wants into a container, and the sperms might help others conceive, where they haven't been able to before, for whatever reason.
Doing it altruistically seems OK. Doing it for egotistical reasons is just weird and creepy.
(I've never done it (man here 👋) and had a vasectomy 21 years ago anyway when (ex) partner and I didn't want any more kids).
