Question about birthweights

(12 posts)(7 voices)
  1. We have a donor selected...she's 7 inches taller than me (I'm 5/3"). However DH's family consists of pretty tall people. His mom is 5'10".
    My question is: DH was a big baby (8 lbs. 12 oz.). If we tx 2 and I end up with twins, could this be a disaster if perhaps donor's birthweight was also in the bigger category.
    OR...does any of that even matter? I mean, maybe my MIL just had a really plentiful diet when she was p/g... lol.
    I just wonder if this is something to consider. Don't want to have a terrible time trying to carry two longer/bigger babies.

    Thanks,

  2. Monica, my sister is pg right now -37 weeks- with her husband's sperm and DE. she's 4'11" and the babies in his family were very big 10 lbs or so. she is having a ton of anxiety b/c they keep ultrasounding and predicting gloom and doom and threatening c sections. she's also rather miserable. there is clearly a genetic piece to how big the baby gets.

    if you're that small and worried about baby size, why are you considering transferring 2? i really pushed my sister to go with an eSEt and she's pretty happy she did.

  3. Monica... You're in luck! I just had this conversation with my Peri yesterday at my 16w sono. I'm pg with donor embie, and our donors' physical features are similar to ours... Donor DH is 5'11", and Donor DW is 5'2". Their 2 full term babies were 7-1/2lbs. I was 9lbs. 7ozs. My sister is currently pg and a patient of my Peri, and she's 37w. She's going to have a 9-1/2lbs. baby! I asked my Peri whether the baby's weight will be determined by the genetics of the mother or the baby assuming I have a healthy diet? He said it'll be a combination of both. So... If I average out my genetics and our baby's genetics, then we'll still have a big baby at 8-1/2lbs.

    BTW... The birth weight of the baby doesn't always determine how tall or big the baby will grow up to be. Look at me... I'm 5'2" and petite. My sister is 5'4" and 8-1/2lbs. at birth. Also, the height of the mother doesn't determine the baby's weight either. My Mom was 5'1", and she only gained 25lbs. with me.
    In case of twins which I didn't ask my Peri, but I'd imagine their weight will adjust to its environment. I'm not a fan of twins. It just doesn't look fun not to mention the potential health risks to the baby, but my RE, OB and Peri have told me that my body will adjust and accomodate the pg.

    I forgot... He went on to mess with me and said that I could have a 12lb. baby and be just fine! He said my body would adjust to it. I told him that I didn't want a 12lbs. baby! I'd be HUUUUUUGE and look like I swallowed a giant basketball! NO Thank-you...

    The only reason we're looking at tx 2 is b/c I have to use heparin as I have immune issues. I not only have not so great eggs, but I have trouble with implantation too apparently. I just want to increase my odds. I've only recently started wondering if twins would be too much if my DH may produce bigger babies. I had 2 singles (DD and DS) with a previous marriage and both were 7 1/2 lbs. and caused me no trouble at all. However, we went with a donor that is quite a bit taller, so it made me wonder. Surely my body would adapt if twins were the outcome. ?

    We will probably just wait and see what we have at 5 day tx and if we will have some to freeze, just tx 1.

  5. devil's advocate here:

    how much does a FET cost at your clinic? plus meds? when we did DE, we weighed the difficulties associated with twins- including double the daycare, double the getting up at night, but also the very increased obstetric risks (and i'm 5'5" with past history of carrying a nearly 10 pounder w/o any complications)- and decided it was worth the $3200 to do two eSETs and avoid risking the twins. we were lucky enough to have success on the fresh eSET and again on a frozen eSET two years later.

    just to mull over

    also, have a friend who talked to our RE about increasing her odds and transferring 2, and he offered her a discount on the second cycle, if needed, so that she could do an eSET.

  6. Ok, thanks. this definately gives me some things to think about! I really appreciate your thoughts.

  7. I am going through the same exact thoughts right now. My DH is 6'1" and I am 5'1". The donor for our first two children was about 5'1" as well. My babies (singletons) were 4 lbs 10 oz and 5 lbs 14 oz. So pretty small. I only gained 17 lbs and 24 lbs with those.

    I just did another DE cycle with a new donor who is 5'7". The donor was a good match on every other level and my husband wanted the height. Needless to say, if we are successful, the child is destined to be larger / taller than our first two children. Given the height of both the donor and my husband, I am concerned about carrying even one larger baby let alone, two (though my husband was only in the 6.5 lb range at birth). However, I just transferred two good looking blasts. I simply didn't want to lose months, take more meds, and deal with a FET which is much more likely to be the case with eSET. If I get pg with twins, I will just be extremely careful about diet and exercise in order to manage the pregnancy.

  8. Can I ask what's eSET? I have one DE child and only want one more and also don't want to risk multiples and can't bring myself to do Selective Reduction.
    Thanks,

  9. It's a single embryo transfer. I don't know what the little "e" is. Maybe elective Single Embryo Tx?

  10. yes, e for elective to differentiate from someone who transfers one embryo because they only had one available (my last FET was a SET but I only had one frozen so nothing elective about it!). It's useful to have that distinction for research purposes.

    That makes perfect sense. Thanks for the explanation!

  12. I would be more concerned about coping with twins after the birth than the actual pregnancy. I think that maternal environment and genetics play a big roll in fetal size. Its protective for the mother not to make babies that are too big for her also, twins tend to be smaller than singletons.
