poll: mode of conception, age and gender of twins

Someone I know was saying today that all the assisted pregnancies (clomid, IUI, IVF etc) that she knew of resulted in girl-girl twins. For some reason this annoyed me, partly because I fail to see the relevence of how a child was conceived once they're born (I know it can impact upon pregnancies) - it never really seems important once faced with the actual child. But then I thought maybe I could do a poll to see whether she's right.

I thought I'd also tag on a poll on a pet theory of mine that older parents - like DH and I - tend to have more girls.

Sorry this somehow seems to be underneath the actual poll, I'm not quite sure how to do it the other way.

 

Well.. we were Clomid and we ended up with boy/girl!

 

I just wanted to say I voted unassisted and under 35- as I was under 35 when the boys were born- but am 35 now....

I was assisted/over35 boy, boy.

 

I was unassisted, boy/girl, under 35... I was only 19 when they were born!

 

When I was pregnant before I found out what I was having, I read stats somewhere that said majority of twins are g/g. Not sure if its true or not and I can't remember where I read it. I just remember this because i thought "yeah, I'm destined to have girls."

 

I am currently 35 so I voted "over 35 - girl/girl", but I was 33 when I had the girls (11 days before I turned 34).

 

My babies are miracles of IVF...boy and girl...I was 36 when I conceived them.

 

INTERESTING...well...let me tell you what about all my "twin" buddies:
I was 20 when I got pregnant, unassisted, girl/girl, but interestingly enough I had a m/c a couple of months earlier and know another lady who also m/c and then got pregnant with twins soon after. Oh, and we haven't had testing done to determine ID or Frat

Next, lady I know was in her early to mid 20's when she got pregnant, assisted, girl/girl, of course frats

Next, 40 yrs old, unassisted, girl/girl, ID's

Next, 20 yrs old, unassisted, girl/girl, frats

Next, mid 20's, unassisted, boy/girl

Next, mid to late 20's, not sure if assisted, but I think so, girl/girl, id's

Next, 21, unassisted, girl/girl, not sure about id or frat

Gosh...I don't know if I know any boy/boy twins! WOW...I have noticed when I am out and run into other twin moms, they are ALMOST ALWAYS, girl/ girl

 

We have boy/girl they were concieved when I was 22 and we did not have assistance concieving.

 

I was assisted with girl/girl and over 35 although I was 34 when I actually got pg and 35 when I gave birth so I may have voted incorrectly.

 

In case you all didn't know I was crazy...I am! Why did I put twin in "quotations" Why?!?!? I meant to put "buddies" in them...like they don't really have twins. I am losing it...I AM!

Wow...the exact same thing for me!

 

I have two friends, over 35, both assisted, one with b/b (frats) and one with b/g. Can I vote for them?

 

B/G, unassisted, when I was 32!

 

I didnt expect that there would be more unassisted under 35 twins. I kinda thought the other way.

I didn't read all the responses, but I know that from my group of IF friends, there were more boys than girls, or just about even.

 

assisted over 35 boy/boy

I think it's interesting that both you and your friend had miscarriages and then twin pregnancies soon after. That's exactly what happened to me too. I miscarried at 9.5 weeks in July 2005 and got pregnant again around Thanksgiving, about 4 months later. How long between your miscarriage and twins? I had boy/boy twins, as did my mother - both of us unassisted at the age of 27. We think our boys are ID and I know my brothers were.

 

We didn't use any assistance and were under 35 and have g/g twins.

 

Boy/girl here, conceived at age 27... on Clomid

 

Interesting! We are under 35 and have assisted b/b ID's. Come to think of it, though, we dont' know any g/g twins. Oh, yes we do. One pair...I forgot. But, other than them, I only know several b/b twins.

 

Under 35 non assisted id girls for me.. most twins I meet around here are b/g

I m/c at 6.5 to 7 weeks (i found out I was pregnant and 3 days later m/c, so it was an early one) in March 2005 and found out I was pregnant June 23, 2005 (remember the day...it was my dad's bday)

I can't say whether I think mine are ID or Frat...I really get so many mixed opinions...some people think I'm crazy b/c I say I don't have any trouble telling them apart, and others think people who can't tell them apart are crazy. So...not sure what would go along with the twins after m/c theory.

 

Interestingly, I read that b/g is supposed to be the most common combination - and an earlier poll I did (I'll have to do a search ) seemed to prove it; however, not this one so far.

In our case, our b/g twins were conceived with IVF when I was 41.

Unassisted, I was 22 at conception, girl/girl

 

Unassisted at 25, girl/girl, unkown (ID/frat).

 

this is really interesting. non assisted b/g under 35.

 

I was unassisted/under 35/girl girl

 

I was 25 when I concieved unassisted with ID G/G.

 

Of the 4 women I know in person who had assisted twin pregnancies, 3 were B/G and 1 was B/B. I had spontaneous twins and they are G/G. So there, stupid friend of Lili's! :lol:

 

We were on Clomid and had b/b twins when I was 25.

 

IVF, under 35 (at the time -- I turned 35 the month after my twins were born), girl/girl twins.

My SIL, for what it's worth, also did IVF, she was 36, and she conceived boy/boy twins.

Among the "assisted" twins I know, I think it's pretty evenly split. That's a very small sample size, though.

Statistically, all other things being equal, 50% of twin sets should be b/g, with 25% each being b/b and g/g. And any theory about assisted vs. unassisted conceptions could really only apply to IVF, since that's the only type of assistance that means anything from the sperm's perspective!

ETA: Although I suppose you could speculate that the "assistance" has some effect on the woman's uterus which then affects whether boy embryos vs. girl ones survive long enough to be detected... I haven't read anything that suggests this, though.

Me too....1st time unprotected. I Have twin sisters...

Someone correct me if I am wrong, but I saw reference to someone having ID girls, but that she may have had assistance.
I was under the impressions that Infertilty Treatments did not produce ID, only Frats...is this true or am I totally out to lunch...

I have 4 friends with twins:

2 are non assisted b/b frats (close to or around 30, I think)
1 is assisted b/b frats (the mother who just past away) (23)
1 is non assisted g/b (24-ish)

 

I was on birth control and had been for seven years when I found out I was pregnant with my girls.
