Boy/girl twins any idea whats going on?

Super interesting stuff gals! While I'll defer to the experts on this one, I was of the impression that IF you are going to pop out two eggs it will happen within a 12-24hr period and is pot luck whether its from the different ovaries, but I believed it was more than likely from the same one....but I'll go and check that out again and am happy to be corrected! Also, just because you have the ability to hyperovulate does not mean it will happen every cycle. Conversely, it may happen more often than you realise and one egg gets fertilised and the other does not therefore resulting in a singleton pregnancy.

But the idea of B/G twins while swaying is certainly interesting. I think Atomic's theory is incredibly sound. I also think that some things are just beyond our control!

Maybe B/G twins are caused by a greater time lapse between the two eggs being ovulated and B/B G/G are a closer gap in time?

No, they're not necessarily but they can be. They can be released up to 24 hours apart - unusual, but it can happen. That's kinda what I suspect, because it may be the follicular fluid and the egg's temperature that attracts the sperm to the egg at first, and only once the sperm gets up close to the egg, can it "sense" the egg's presence.

Yes, that is absolutely possible. 15-20 eggs develop in BOTH ovaries every month and most times only one makes it to maturity. Both scenarios can happen - one ovary can release two eggs or both ovaries can release one egg, or in the case of higher order multiples, even more than one or two eggs.

I think there are a lot of diff. scenarios that could lead to a clump of sperm hanging out together reaching one egg and then only two or three making it to the other egg. (It takes more than one sperm to fertilize the egg.) The dynamics of the female reproductive tract are always changing, like the water in a ****** carrying debris, and it seems logical to assume there would be places where sperm would pool and other places where it would flow more freely.

Great response ladies,this makes more sense to me now with the theories you mention.I was thinking about this subject because my mother is a fraternal twin GG and i know this is more common than BG.I wish I could get some gg twins!

Well you have a really good chance for twins since your mom is a faternal twin and you have multiple pregnancies, hope you get a set of beautiful twin girls :)

I have two friends expecting twins at the moment - one lady has 3 boys and is expecting BB twins and one lady has a boy and a girl and is expecting GG twins. There's obviously something in the air - good luck!

Well i always wondered about my grandmother if she had the hyperovulate gene or if it was the fact that she was dealing with reproductive cancer,nobody is sure what kind exactly. She was sick from the time she had my mom and her twin,they oppened her up to see what was happening i suppose and the feeling was according to family that just made it spread faster,she passed when my mom was 3.I always wondered if ovarian cancer or such could cause hyperovulation possibly.

Zanacal nice job on the weightloss! awesome job lady!!

Thank you :D

I'm sorry to read about your grandmother, so very sad x
