It used to be that older couples going through IVF fertility treatments would routinely end up with twins or triplets. It was an odds game. If you transferred more embryos, it was believed you’d have a greater chance at pregnancy. But a new study through the Colorado Center for Reproductive medicine shows that’s no longer necessary. The study shows that single embryo transfer, along with chromosomal screening, can be just as successful for women over 35 as it is for younger women. “This is just a very exciting advance I think, to enhance not only the success rates of what we do, but most important the safety of what we do,” said Dr. Eric Surrey, Medical Director for the Colorado Center for Reproductive Medicine. He says the risk to a mom and baby increases 7 fold with multiple births. “There’s a much greater risk of miscarriage, of preterm birth, preterm labor, any complication that goes on in pregnancy,” Dr Surrey said. The goal is to have healthy moms and healthy babies.
Single embryo transfers, with the screenings, worked for the Krummen family of Denver. Unable to get pregnant on their own, Kaylyn and Paul had two children through IVF. They had two healthy embryos, and transferred them one at a time, so there was no risk of having twins. “We were open to the idea, but it’s a lot safer for the mom, and the baby just to have one baby during pregnancy,” Kaylyn said. Now raising two little boys, she is very happy with her decision.
