If you have two children of the same sex, are you statistically more likely to have a third child of the same sex??

my aunt had 4 m/c all girls and she has a healthy boy then she had another 2 m/c all girls. think she is unable to carry girls

Enid · 28/01/2006 21:42

hate that myth

surely it is a myth (unable to carry one sex)

hub2dee · 28/01/2006 21:50

Possibly that stat is skewed by sex-specific chromosomal abnormalities incompatible with life IYSWIM ?

tamum · 28/01/2006 21:55

Could be but I can't for the life of me think of something that would be lethal for females and not males. Maybe it will come to me.... I certainly don't think there's any evidence that people can "carry" one sex but not another, even in the animal world.

Enid · 28/01/2006 21:56

good

because it pissed me off when I had a m/c and people said it was because I couldnt carry boys

MerlinsBeard · 28/01/2006 21:56

not scientific at least that i know of but it helped her alot to think that x

tamum · 28/01/2006 22:02

No, I would have been pissed off by that too Enid. I think that in general what hub2dee said is probably at the root of these sayings though- if you had someone who was a carrier for an X linked disease that was lethal in males then you could get a bias, but even then 50% of male babies would be unaffected.

notasheep · 28/01/2006 22:02

50/50 chance i would imagine.
My sister has EIGHT children:
boy,girl,boy,girl,boy,girl,boy,boy.

Enid · 28/01/2006 22:03

yes I see

find it very unlikely that either dh or I are carrier for that though as lots of boys/girls in both our families

maybe this next one will be a boy and they can all feck off

Calista · 28/01/2006 22:03

I have 2 boys, conceived on exact day of ovulation both times ( have several v. clear indicators when I ovulate).

Has anyone read Dr. Shettles book 'Choose the sex of your baby'? Apparently research shows that some men have predominately male sperm or female sperm, eg. 80% female/male. And some womens' vaginal environment can be quite alkaline/acidic which favours one sex of sperm over the other.

I'll be trying the method of BD'ing several days before ovulation now I've got my 2 boys, to try for a girl 3rd time. Time will tell!

Enid · 28/01/2006 22:04

I think its all a load of crap

and completely random

tamum · 28/01/2006 22:05

Oh yes Enid, wildly unlikely, and absolutely no evidence that could be true as far as I can see. Chin up

Caroline5 · 28/01/2006 22:59

My Mum's side of the family seems to have a definite slant towards girls - I have 2 girls, my brother has 2 girls, my Mum is one of 2 girls, her father was one of 10 children (7 girls, 3 boys).

QE2 · 28/01/2006 23:05

Whilst I logically think it is a 50/50 chance each time you conceive, I have a fancy that I am more prone to having boys.

I have g/b/b/b/b and think we'll stop there as i just know it will be another boy. Not that i care, dh desperately wants a girl.

QE2 · 28/01/2006 23:06

On my dad's side of the family, out of a total of 11 of his grandkids, 8 are boys.

ShaysMummy · 28/01/2006 23:19

i think the same as dottydot. i used an ovulation kit (as i was too impatient!) so we did the biz the moment i ovulated. i had a boy. I am preg again but I wasnt watching the dates and the 14 day thing, i thought this time i'd just see what happened.
I am not hoping for either sex. if i have another boy that's dandy and a girl, just as dandy! i am secretly thinking maybe it's a girl but i have 2 bro's and dh has a bro.
mil swears because of this it will be a boy. as i said though, i think it depends on who gets there first!!

lucyhoneybee · 28/01/2006 23:43

No boys born in my family for 25 years.Then after 2 ds, I had a boy. both girls unplanned, boy planned; conceived day I ovulated.
therefore seems would be easier to "choose" boy than girl? next time i don't mind, would love one of whatever.. or one of each...

ShaysMummy · 28/01/2006 23:46

yeah i think you can sort of 'choose' a boy.

JanH · 29/01/2006 00:04

On my dad's side of the family there were 6 grandchildren, 3B in 1 family and 2B/1G in the other.

Of the 5B:
2 have no kids
1 has 3G and 1B
1 has 2G and 2B
1 has 1G
(and I have 2G and 2B)

so 5B and 1G produced 8G and 5B.

Does this help at all ?

expatinscotland · 29/01/2006 00:11

im one of two girls. my sister has two girls. i have two girls. coincidence entirely.

so statistically it is 50/50 but some peopel dohave a predispostion to have only one sex.

SoupDragon · 29/01/2006 12:55

Yes, and it's that which skews the statistics in general to make it more than a 50/50 chance of having a third the same.

Avalon · 29/01/2006 13:47

Girl, girl, m/c boy, girl here.

The m/c was a genetic thing though, not gender related (I had tests done).

workingmumnhs · 29/01/2006 16:21

DP and I are going to try for another child in the summer. He has had three girls (Two to other relationships) We would really like a boy. Have bought some books about it but not read them yet. Is it likely to work

juuule · 29/01/2006 16:36

We had boy, m/c, boy, girl, boy. At that point I was convinced that the m/c was a girl and it was good fortune that I had carried the girl to term.

However, we then had m/c, girl, m/c, m/c, girl, girl, girl, m/c, m/c, girl, m/c, m/c.

So b,b,g,b,g,g,g,g,g.

I do wonder if there is something that makes it more likely to have boy or girl. My mil had 5 boys and her 3 sisters all had boys. However, out of 19 grandchildren only 4 are boys.
