Odds of two spontanious sets

We got pregnate with our twins while on birth control We have a beautiful set of faternal b/g twins. we are thinking that we want at lease one more baby befor we are done, so i was wondering how many people who had a spontanious set of twins ended up with a second set of spontanious twins.
I would def be up for having another set, we already have two of everything

 

I think that I've heard somewhere that once you have a set, your chances for another quadruple. Plus, if you're older, your chances are higher. Also, with more pregnancies your chances increase. We are planning on more, too. Twins are a lot of work, but I'd do it again in a heartbeat.

 

We have spontaneous identicals. It's my understanding that the same odds that apply to fraternal twinning don't apply to Ids. Anyone know more about this? My grandmother was a fraternal twin though, so it makes me wonder...

We had always planned on two kids, but I could see having one more (two more would be kinda pushing it for us . Would love to know if anyone has information about the odds of conceiving another set after spontaneous IDs.

Sorry! Realize this does not in any way answer YOUR question .

 

I think the odds of having a repeat set of fraternal twins id 1 in 5, or a 20% chance with each subsequent pregnancy. HTH.

Since ID twins are spontaneous, the odds of you conceiving a second set of ID twins is 1 in 250, which is the same as the odds you had to conceive your first set. I hope this makes sense, HTH!

 

My last pg were twins (I m/c'd one twin) as a result of clomid - I thought! I asked my doctor about our chances of another set using clomid again and he did say they went up. So we didn't use any fertility drugs and here I am 36 weeks pg with twins. I have no idea were all these twins came from, we have absolutely no multiples in our families. I have also heard the chances of multiples increases with age, number of pgs, and past multiple pgs.

That's what I've heard too - but I also heard that it can be more likely to have twins after ID twins - just because your body has already had two - it is fooled into thinking that that's what it is supposed to do??? Anyone else heard this?

 

Interesting! My first pg was ID twins (lost to TTTS). I was told I had no more of a chance of spont twins again as any other woman. Now I have frat twins from IVF. I was told now I have a better chance of spont frat twins due to my age - OLD But man ooh man, many of you with 2 sets of twins really throw all the explanations for chances off the charts

I've read something similar to that -- some scientists think that many more sets of twins are conceived than born or even known about because the mother's body sees a twin pregnancy as abnormal and either miscarries both or reabsorbs one (vanishing twin syndrome). The theory then is that the body of a mom who has had a successful twin pregnancy recognizes twins as normal, and will be more likely to retain (that's not quite the word I want) a twin pregnancy. I don't think that this tendency has a huge impact of the likelihood of repeat twins after IDs, though.

My doc told me I had a 1 in 50 chance. Is it actually higher then that?

I heard its a 50/50 shot. When the time is right, I'll be eating a ton of yams and go on b/c for a few months to try for a second set.

 

We get this question asked a lot. There are many factors to consider, but to put an average number out there, I would say that any woman who spontaneously gives birth to fraternal twins has a 1 in 15 to 20 chance of having fraternal twins again in a subsequent pregnancy (four times greater chance than natural odds).

The odds of having identical twins would be the same standard 1 in 250 chance; I've never read anything concrete on the chance that you'd be more likely to have fraternal twins increases. Perhaps you'd be less susceptible to a vanishing twin, but even that would be difficult to substantiate. We think our 17-month-old started out as a twin due to an empty second sac at his first ultrasound.

 

After 3 boys, I want a girl. However, DH (not me) is scared to death that we'll end up with triplet boys if we try for a girl. Doctors guestimate that 1 out of every 6 pregnancies is a twin pregnancy, but that not all of them make it past the 12 week pt. Given that our bodies think its normal to have 2 at once, I think there's a good shot at having another set. I keep telling my DH that we've done it once, we can do it again.

Do yams increases your chances of conceiving twins???

I'd LOVE to have another set with my next pregnancy! They are such a blessing!

 

I *think* that yams increase your fertility.... and just a little tidbit --- more spontaneous twins are conceived in July. (That's what I heard anyway!)
