Why Doctors Don't Want You to Have Twins
With IVF treatments, twins have basically become the new norm—46 percent of IVF births are multiples, mostly twins. But now fertility experts want to change that. The new goal: single births, even when using IVF. Why? Twins have a much higher risk of being preemies and having serious health problems that could potentially last a lifetime.
The most recent info from the Center for Disease Control and Prevention states that 37 percent of IVF babies, who are multiples, are born premature, while only 3 percent of babies born without fertility treatments are twins, and of those about 12 percent are preterm.
Many women who've struggled to have kids are excited to have twins—even asking their physicians for twins—because they may not have the money for multiple IVF treatments (each round can cost up to $20k!), or they would love to have two kids at once, and never have to go through pregnancy again! But doctors fear that couples are making a rash decision without really knowing the increased medical risks for babies and moms (risk of gestational diabetes and preeclampsia are higher).
The American Society of Reproductive Medicine's recent guidelines state that women should be counseled on the risks of multiple births and embryo transfers and that this discussion should be noted in their medical records. According to the guidelines, "for women with reasonable medical odds of success, those under 35 should be offered single embryo transfer and no more than two at a time." They are open to more embryos being implanted, if the woman is over 35.
According to Valley News, with stronger screening of embryos, success rates for single embryos could be nearly as good as when two or more are used, say experts. The new techniques include maturing the embryos a few days longer, improving viability and allowing cells to be sampled for chromosome screening. Embryos can be frozen to allow test results to come back and more precisely time the transfer to the womb.
Taking these steps with single embryos results in fewer miscarriages and tubal pregnancies, healthier babies with fewer genetic defects and lower hospital bills from birth complications, many fertility specialists say.
I'm really torn on this subject, because I don't think any of us want more Octomoms running around out there, or kids with health problems. But—and it's a big but—all of the women I've known who've had IVF (and I should note that all of them have been over 35), have had twins, and are beyond thrilled with their decision to have multiple embryos implanted. Many of them did have complicated births—including extended bed rest, spotting, C-sections, and breathing problems in the children that caused them to stay in NICU for weeks, up to months after their births.
All of that said, as far as I know every single one of them is a happy, healthy kid with no lingering medical issues (at least so far—fingers crossed!). And even though the pregnancies and births were more complicated, required more doctor visits, and now they have twice the expenses with two little ones running around at the same time, the parents' love for their two cuties made all of that initial anxiety worth it for them, and they would never, ever want to have traded that experience in for a single birth.
